Embodiment

Describe the technology being managed to the program executive capability of the program for performing one or more users.Extremely In some few embodiments, the program executive capability managed includes one group one that supplies user to be used to perform one or more programs Individual or multiple calculate nodes.In addition, this group calculate node related to user can be dynamically changed during use, can to manage user The amount of the program executive capability obtained from this group of calculate node.The modification of pair this group calculate node related to user is each Can have in embodiment various forms (for example, to change the quantity of calculate node in the group, for example, by dynamic addition and/ Or delete calculate node), and can trigger in a variety of ways in each embodiment (for example, dynamic based on being specified by user State instruction, the automatically determining of situation met, based on the service for providing this group of calculate node based on the predefined trigger of user Automation mechanized operation etc.).What the dynamic of the program executive capability included below on that can be obtained from one group of calculate node was changed Other details.In addition, at least some embodiments, these technologies can combine the multiple customers for representing the service or other use Family is used to perform the program execution service of multiple programs (" PES "), such as network access program execution service, and it is provided It is used to performing multiple calculate nodes of the program of long-distance user (for example, providing on one or more physical computing systems Multiple physical computing systems and/or virtual machine).Some or all of these technologies can also pass through program execution service system pipe The embodiment of reason device module and/or program execution service ability maintenance manager module is implemented automatically, and following article is in more detail Description.

As it was previously stated, in each embodiment, to one group of calculating section of one or more programs for performing user The dynamic modification that point is carried out can have various forms and can trigger in a variety of ways.As an example, this group of calculate node Program executive capability can measure at least partially through the quantity of the calculate node for a group part, and can pass through change The calculate node quantity of the group (for example, to improve program executive capability by increasing calculate node quantity, and passes through to change Calculate node quantity is reduced to reduce program executive capability).The modification of such calculate node quantity can be used for (such as) in the group Some or all of calculate nodes provide or can obtain same or like quantity computing resource (for example, amount of ram, hard drive space, CPU performs cycle, network bandwidth etc.) in the case of so that the given percentage change of calculate node quantity is corresponding to the group The same or similar percentage change of total computing resource and program executive capability.In other embodiments, the group calculates section Some or all of point can one or more important ways different (example in terms of the amount of its obtainable computing resource Such as, if configured using two or more different types of calculate nodes, if each calculate node is independently from other meters Operator node configuration etc.) or be otherwise in its offer program executive capability type in terms of it is different (for example, according to special With hardware, the type etc. of software program), but the program executive capability dynamic modification of the group can really be based at least partially on modification should The quantity of group calculate node, or other manner can be conversely based on (for example, being another by a type of calculate node configuration change Type), such as other places discuss in more detail.

In addition, at least some embodiments and situation, the program executive capability of one group of one or more calculate node The mode that can be differently configured from the quantity of calculate node is measured and changed, such as the one or more types provided based on the group Computing resource total amount (for example, amount of ram, hard drive space, CPU perform cycle, network bandwidth etc.).In addition, at least some In embodiment, it is contemplated that other factorses in the program executive capability for measuring and specifying one group of calculate node, more such as or Between the geographical position of all calculate nodes, some or all of calculate nodes correlation (for example, by it is at most maximum geographical away from From or at least minimal geographical separating distance, by most maximum network be delayed or at least minimal network delay separate, be separated into two Or more independent data center or the other calculate node set that will not simultaneously disable etc.), specialized hardware ability and/or soft Availability of part ability etc..Other details included below on measuring with designated program executive capability.

The PES or other systems being managed to one group of calculate node of one or more programs for performing user can Automatically determine how and when enter the dynamic modification of line program executive capability to the calculate node group in a variety of ways.For example, extremely In few some embodiments and situation, PES or other systems can carry out certain form of program executive capability in direct mode and repair Change, and the modification of other types of program executive capability can periodically carry out carrying out (for example, to prolong in an iterative fashion in other words Late and be aggregated in a period of time (such as from carry out it is one or many polymerization modification before) it is to be made through ask or with The multiple modification that other manner determines.If polymerizeing multiple program executive capability modification determination values within a period of time, on The information of polymerization modification determination value can be used in a variety of ways to improve the implementation of program executive capability modification.If for example, two The program executive capability modification of secondary determination corresponds to the modification of opposite types (for example, to increase and reduce calculate node quantity, increase Add and reduce and can use total internal memory etc.), then modification can be polymerize in a variety of ways twice, such as by chosen come partly or completely Cancel out each other entirely, or conversely by selecting the higher priority in pending modification twice come instead of another modification.In addition, If the program executive capability modification determined two or more times corresponds to similar or complementary types modification (for example, so that meter Operator node quantity increases specified amount, makes to can use total internal memory to increase specified amount etc. comprehensively comprehensively), then the modification of those determinations can be each Kind mode similarly polymerize (for example, to select the modification that the single for meeting some specified values determines, such as maximum is changed, most Small modifications, the modification with limit priority, the modification determined first, modification for finally determining etc.；To accumulate various determinations Change and use the modification amount of accumulation；Deng).It is included below regarding determining how with when make each class method executive capability and change Other details.

In addition, when PES or other systems perform the one of one or more programs group of calculate node dynamic to representing user When entering the modification of line program executive capability, PES or other systems can further carry out various operations so that specific program is performed into energy The causal law information of power modification or other attribution of responsibilities.Attribution of responsibility may include (such as) identification occurred in relevant time period Particular event, wherein each event can cause program executive capability dynamic to be changed, and by one in these events or More than one piece is attributed to some or all of program executive capability dynamic modification carried out during or after the period.For example, In at least some embodiments and situation, the modification of some program executive capability dynamic each can trigger (example by single particular event Such as, if this group of calculate node failure becomes unavailable in other words, automatic start provides replacement meter to system to the group immediately Operator node, at the same calculate node unavailability turn into directly cause system auto-action with provide substitute calculate node single thing Part).In at least some embodiments and situation, other program executive capability dynamic modifications are each attributable to multiple events Combination, each in these events each contribute to or potentially contribute to ability modification (if for example, multiple independent events each The calculate node quantity increase of the group is needed or indicated within a period of time, and these events are aggregated to terminate in the period The quantity of the single calculate nodes of Shi Zengjia, at the same each independent event turn into cause the follow-up auto-action of system to increase indirectly jointly Multiple events of calculate node quantity).

The attribution of responsibility for the specific program executive capability dynamic modification that pair calculate node group related to user is carried out with Can have special benefit in the case of lower, for example, for the modification of at least some program executive capability and to user charge when (for example, If PES or other systems be due to provide each calculate node of the group, each other measurements of program executive capability and/or The charging system charged based on other foundations to consumption user).In such cases, user can not only receive and check On changing the information of corresponding expense with specific program executive capability dynamic, and the responsibility related to checking can be received Attribution information, so that user is able to confirm that the reason for those program executive capability dynamic is changed and appropriateness.It is at least some this In class embodiment, attribution of responsibility information can be produced to be shown to user with people's readable format, allow the user to understand respectively Individual auto-action why by PES or other systems included in people's readable information come the explanation taken.In other embodiments In, can also various other modes (including the PES or other systems for passing through the other operations of automatic start) use such responsibility Attribution information.In addition, at least some embodiments, all kinds of inquiries that may be in response to receive at user or other sources come Produce and/or use attribution of responsibility information, these inquiry such as on identify which (multiple) event for cause one group one or The request of the reason for modification of specific program executive capability that multiple calculate node availabilities indicate or other changes and/or pass Which referred in (multiple) change in availability of (multiple) program executive capability modification or other calculate node groups by one or more Asked caused by the event shown.Attribution of responsibility information included below on determining and using the dynamic modification of program executive capability Other details.

In all cases, the technology for the dynamic modification of automatic management program executive capability can provide various benefits Place.For example, by polymerize it is multiple through asking or determining program executive capability dynamic modification to be considered, PES or its Perhaps, how its system carries out polymerization modification if can optimizing, and the change repeatedly of calculate node is minimized, and this can make progress The some or all of calculate nodes additionally changed are temporarily unavailable within a period of time.In addition, user can be predefined based on one group All kinds of triggers of the performance characteristics of calculate node, while when certain triggers are satisfied, optionally improve or reduce automatically Program executive capability is (for example, improve the program executive capability of one group of calculate node with passive (reactively), so as to meet to count The temporary increase of the calculated load of operator node group；Actively (proactively) improves or reduced the program of one group of calculate node Executive capability, so as to meet the anticipated demand that will appear from of other program executive capability and/or meet that existing program performs energy The anticipated demand that will appear from of power lacks, such as according to the weight on particular performance characteristics and/or instruction program executive capability The trend changed over time of the historical data of multiple use pattern；Deng).Or user can be wished the journey of one group of calculate node Sequence executive capability is maintained at specified level or its nearby (for example, calculate node specifies required constant), and can be to the group meter Operator node carries out various modifications so that available programs executive capability is maintained at into the specified level (for example, referring to that will deviate automatically Fixed the desired amount of actual calculate node quantity is recovered to specify aequum to this).Such as when each execution in this group of calculate node The different duplicates (for example, alternative form for use as total calculated load in the group) of identical program, and change calculate node Quantity to manage the workload handled by each calculate node when, such technology can be used, or perhaps these technologies are used Each calculate node in one group is not performed each in the case of the different duplicates of identical program (if for example, the group meter The different subsets of operator node each perform the duplicate of distinct program, such as so that some calculate nodes perform application server programs And other calculate nodes are made to perform related database server program；If some or all of these calculate nodes are such as Implement the different piece of single program in a distributed way；Deng).In addition, when to group addition additional calculations node when, PES or its Its system also optionally takes other actions at least some of situation, such as is prepared with providing added calculate node One or more programs are performed, or further trigger the execution of one or more programs automatically in the calculate node added.

As it was previously stated, related all kinds of tactile of user can predefine to dynamic changes multigroup calculate node program executive capability Device is sent out, and those triggers are subsequently used in the corresponding program executive capability automation dynamic for triggering the calculate node group of user Modification.As an example, definable specify calculate node specific aequum or one or more computing resources it is required total The trigger of amount, such as it can be used for corresponding calculate node group being automatically held in required calculate node quantity or required calculate provides Source total amount, or the opposite calculate node quantity or computing resource total amount (if meeting specified value) for being used for change and specifying.At it In its situation, definable specifies the calculate node quantity of one or more computing resources or the specific of total amount definitely or relatively to change Trigger, for example, if the performance characteristics of one or more instructions of calculate node group reach specified threshold or perhaps met Specified value, then its can be triggered (for example, being maintained in the specified range of set period；Particular tendency is represented, when such as specifying Specified variable quantity in section, or such as specific " acceleration (acceleration) " or rate of change；Conform or correspond to one kind Or a variety of designated modes (such as historical data of the reuse pattern from representation program executive capability)；Meet multiple performance Other combinations of the specified logic or value of characteristic, such as logical operator (AND, NOT, OR etc.) and/or with other can be used Mode is combined；Deng).In other embodiments and situation, predefined trigger can be according to being not belonging to calculate node group The information of performance characteristics be otherwise satisfied (for example, based on meeting one or more specified times (for certain trigger Part or all of the standard of device) current time；Based in the current calculating measured in a manner of different from performance characteristics The status information of the one or more programs performed in node group, such as by (such as) the arranged or perhaps known or phase The current calculated load for hoping the workload completed by one or more programs represent；Based on what is do not performed by current calculate node group The performance characteristics of one or more of the other configuration processor or other status informations, for example, if current calculate node group is held with other Line program interaction supports these programs in other words, so as to when the calculated load in other configuration processors increases or decreases, example Such as improve the program executive capability of current calculate node group；Deng).Such performance characteristics can be based on one in this group of calculate node Or multiple any measurable attributes or the other yardsticks corresponding with the operation of these nodes, including following nonexcludability is clear Individual event：The absolute or relative usage amount of one or more computing resources of single calculate node is (for example, used free memory Percentage amounts or cpu cycle utilization rate, the absolute magnitude of used network bandwidth etc.)；One kind of all this group of calculate nodes or The absolute or relatively total usage amount of a variety of computing resources；In response to absolute in the communication from outside computing system or relative prolong When (latency) or it is other delay (delay) amount；Calculate node is absolute or relative in one or more required actions are completed Failure amount；Deng.In addition, at least some embodiments and situation, trigger meets that situation not makes the trigger direct Specify and change the specific program executive capability occurred when being satisfied, but can be notified appointing system or module, and And the system or module can ask to carry out specific program executive capability modification (for example, unchanged predefined ability modification； Such as the ability modification being dynamically determined based on condition at that time in notice；Deng).In addition, in some embodiments, PES or Other systems can carry out various operations to monitor one group of calculate node, to determine some or institute of the trigger related to the group There are a performance characteristics, or otherwise can obtain the performance characteristics of such monitoring (for example, from monitoring the meter from another source The third party software of operator node, from calculate node perform with monitor the calculate node and optionally report monitoring information it is soft Part etc.).In addition, in some embodiments, PES or other systems can have draws when meeting the instruction trigger criteria of trigger The system of hair program executive capability dynamic modification defines trigger, or can otherwise be automatically determined with right under particular cases Calculate node group makes certain form of change.

When the trigger of definition specify one or more computing resources calculate node quantity or total amount it is specific definitely or Relative change, and automatically determined based on the present case of corresponding calculate node group to meet one or more of the trigger of definition During individual specified value, PES or other systems may automatically determine whether and the program executive capability how to be specified to trigger Modification.For example, certain form of designated program executive capability modification can be carried out immediately (for example, terminating using one or more meters The request of operator node, request of the trigger for implementing immediately etc. is specified based on user), and can be specified other types of At the end of the modification of program executive capability is deferred to the polymerization period, to be regarded as what is asked or perhaps determine during the period A part for more secondary program executive capability modification of polymerization.Similarly, for example, based on program executive capability dynamic modification type, Based on from user immediately or the explicit request etc. implemented of delay, it may be determined that repaiied by the program executive capability of user's dynamic requests Change (for example, via GUI, or the graphic user interface of PES or other systems；By via the API or PES of definition or its The user program of its systematic difference Program Interfaces；Deng) to carry out immediately and/or temporary delay and poly- in a similar way Close.In addition, when determining how the combination for more secondary program executive capability modification that management determines, it is in some cases, different Priority can modification correlations different from determination.It is if so, for example different from the trigger being satisfied preferential for assigning User's request that the dynamic of level (for example, higher or lower priority) is specified or other user instructions, assign different priorities (for example, for assigning higher priority compared with improving the request of program executive capability for the different types of modification through determination Reduction program executive capability request for) etc., such priority can be assessed in a variety of ways.It is included below on use User-defined trigger and the other details for determining performance characteristics.

In addition, at least some embodiments, multiple attributes based on following the trail of and using corresponding calculate node group, or Say it is based on controllable parameter each related to one or more calculate nodes in the group, PES or other systems can manage fixed Phase polymerize multiple through determining the modification of program executive capability repeatedly in other words.As an example, by the meter of calculate node group Operator node quantity is used as the yardstick corresponding with the program executive capability of the calculate node group, and PES or other systems can be directed to should Calculate node group and keep and using at least three kinds measurements that are mutually related, as described below：The required calculating section of calculate node group Point quantity, such as when starting the calculate node group, associated user can initially be set to it, and the quantity can be according to tactile Hair device meets that the user that situation and/or dynamic are specified is asked to change；The actual calculating of currently available calculate node in the group Number of nodes (for example, being determined by the continuously or repeatedly monitoring to this group of calculate node)；With currently available calculating in the group The calculate node quantity of the offical record of node (for example, as triggering one or many program executive capability to move for the last time State is determined when changing, and is optionally updated frequently by continuously or repeatedly monitoring).The calculate node group it is such more Individual attribute can be used in a variety of ways (such as) continuously or repeatedly measure actual quantity and thus update offical record quantity (for example, based on be monitored to this group of calculate node), and for periodically attempt by the quantity of nearest offical record update with Meet current desired quantity (for example, when considering how and whether will be to repeatedly polymerizeing through determining that modification is combined).

As it was previously stated, PES or other systems can further carry out specific program executive capability of the various operations could be made that The causal law information of dynamic modification or other attribution of responsibilities.For example, as it was previously stated, traceable perform with the program of calculate node group The corresponding event of request of ability dynamic modification, including the dynamic instruction specified of the user received and automatically determined expired The predefined trigger of foot, and the action taken automatically by PES or other systems in some embodiments is (for example, base In the monitoring of progress, for example, if determine that calculate node is frozen or perhaps is not useable for carrying out required activity, it is automatic to close The part that calculate node is used as to its current calculate node group is terminated in other words).Similarly, can similarly tracing computation section The actual change of the program executive capability of point group, such as change (example corresponding with the event of generation and/or other capacity variations Such as, the example that calculate node failure becomes unavailable in other words).As an example, various information concerning events can be stored up In the presence of in the first database table, and can will be on the various information storages of capacity variation or other change in availability in the second number According in the table of storehouse.If the relation between identification particular event and specific change in availability is (for example, particular event causes specific can use Property change immediately occur), then can by by identical close knot relevant identifier with its of the event and the change in availability Its information preserves to follow the trail of the knot of the corresponding pass between the event and change in availability together.Can be alone or in combination in multiple events Ground causes specific change in availability but causal law is not attributed in other situations of individual event, single close can be tied into correlated identities Stored together with according with each other information on the change in availability and those events, and can also with one Or the other information of a number of other change in availability preserves (if they can similarly be attributed to those alone or in combination together The multiple events of identical).Thus, for example if multiple events of given calculate node group occur during the single polymerization period simultaneously And one or more program executive capability changes occur to occur (for example, making during the identical polymerize the period or immediately after For a part for the Coordinating Activity carried out at the end of the polymerization period), and if those events are not directly attributed to Any one of one or more of capacity variations, then the combination of all these multiple events be all attributable to it is one or It is each in multiple capacity variations.Further detail below (including reference picture 2B) included below on this causal law attribution.

In addition, in a similar way, it is multiple it is such needed for, actual and formal attributes can be tracked and be used for and calculate node The corresponding one or more of the other controllable parameter of program executive capability of group, all formula weights as required first group, actual and positive Cpu cycle overall average utilization rate, required second group, network bandwidth overall average utilization rate of actual and positive formula weight etc..In addition, When following the trail of and using the multiple parameters corresponding with the program executive capability of calculate node group simultaneously, PES or other systems can Attempt to manage all parameters, such as to change calculate node group, so as to the cpu cycle overall average utilization rate needed for obtain simultaneously and Required network bandwidth overall average utilization rate.As another example, the multiple parameters of calculate node group may include in the group respectively The calculate node quantity and specified geographic location of individual calculate node are (for example, this group of calculate node between the first data center Between 15% and 20%, remaining this group of calculate node is located at one or more of the other data center), while PES or other systems System is attempted to manage calculate node quantity and the calculate node geographical position of the group simultaneously.It is included below on using multiple attributes come Follow the trail of and manage other details of one or more program executive capability parameters.

In addition, in each embodiment, family can be used to access calculate node in a variety of ways for PES or other systems.Example Such as, in some embodiments, at least some distribution in the calculate node that be able to will can be obtained at the PES for configuration processor To one or more users, so that those users can preferentially use so that each in those users can relative to other users Preferentially use those calculate nodes.In this embodiment, the preferential access of these users can be based on can be proprietary or exclusive Use each user of those calculate nodes (such as in a manner of similar to rental) of set period.In addition, in some implementations In scheme, for example, when calculate node is unassigned have the users of these calculate nodes using when and/or when being assigned calculate node User clearly make allocated calculate node can by other users in use, distribute to one or more users with proprietary or At least some in the calculate node preferentially used can be used as excessive program executive capability and used for other users sometimes.So, At least some program executive capability for distributing to first group of user represent it available for (such as on the basis of non-guaranteed) sometimes His user carrys out temporary transient configuration processor (for example, coming for other purposes if necessary to the program executive capability, such as one or more The preferential or reservation of other users uses, then the right to use of excessive program executive capability can be cancelled).In addition, at some In embodiment, PES may include on-demand computing node, it is received available for the dynamic for meeting user's configuration processor asks (for example, When those users ask, the future time in instruction, a period of time in the period in future in instruction etc. perform) so that can One or more programs indicated by the request are performed, with the proviso that the calculate node for being sufficient for the execution of request is being asked Time when (near or) can use (but not ensureing that the request can be met) when.In addition, in some embodiments, immediately (or It is predetermined) on-demand request that performs is satisfied and represents each user come after successfully triggering the execution of one or more programs, On-demand computing node can be ensured to be continuing with until some time in future, some time selected by such as each user, appointed Some somewhat prohibitive time of selection of land, (such as, it shall be guaranteed that PES will not the purposes of preemption for other purposes, but do not protect The calculate node of card configuration processor can fail).In some embodiments, based on variable program executive capability on demand is provided Operator node may differ from calculate node for providing proprietary program(me) executive capability and/or for providing excessive program executive capability Calculate node, so if being not used for providing some on demand in the calculate node of variable program executive capability, then exist In some embodiments, these nodes can be used for providing excessive program executive capability, and energy is performed until receiving variable program on demand Power is asked, and in other embodiments, these nodes may not be used to provide excessive program executive capability.In other implementations In scheme, the program executive capability of single type can be only provided, and/or other types of program executive capability can be provided.

Figure 1A is to show to performing the progress of the calculate node of the program of multiple users available for program executive capability is provided The network of the example of the program execution service of management.For the purpose of illustrating property, some examples and reality are the following described Scheme is applied, wherein providing and managing certain types of program executive capability in a specific way.In addition, in following examples and implementation In some in scheme, the program executive capability provided by one group of calculate node can be in a specific way (for example, be based on calculate node Quantity) measure, can in a specific way (for example, by needed for following the trail of, actual and formal attribute is relative to one or more journeys The purposes of sequence executive capability yardstick) manage, can by associated user in a variety of ways (for example, based on predefined trigger and/ Or the purposes of dynamic designated order) be controlled, it can modify in a specific way (for example, by being aggregated in a period of time It is determined that and delay the modification of at least some program executive capability, then carried out at the end of the period one or many corresponding poly- Modification is closed, such as to change the quantity of calculate node in one group) etc..The purpose that these examples are used for illustrating property is provided and is Simplified for purpose of brevity, and it should be understood that the technology of the present invention can be used in various other situations, and below only Describe some in these situations.

Exemplary data center 170 includes many physical host computing systems 175, physical computing systems 182, PES The PESCMM modules 160 of PESSM modules 180 and PES.In this example, host computing system 175 each provides multiple virtual Machine, and virtual machine (" VM ") manager component with those virtual machines of management is (for example, management program or other virtual machines prison Visual organ), such as shown by the host computing system 175a with multiple virtual machine 177a and VM manager components 179a.Its Its host computing system 175b can similarly include this class component, for simplicity, those other components be not shown herein, and And some or all of computing systems 182 are optionally same with one or more such virtual machines and/or VM manager components (not shown).Each in the virtual machine provided by host computing system can be used as different calculate nodes in PES, example Such as so that the first virtual machine calculate node on host computing system turns into a part for the first calculate node group of the first user, And the second virtual machine calculate node in the same host computing system is set to turn into the second calculate node group of second user A part.Or in other embodiments, some or all of physical host computing system at the data center Any virtual machine may not be provided, such as conversely perform one or more journeys directly as the final consumption user for representing PES The calculate node of sequence.In addition, in some embodiments, each computing system 175 and 182 can have different abilities, can With it is different it is used in connection with take, different types of user program can be supported (for example, the software image of various sizes of virtual machine Example, or there is different types of resource criterion and/or computing resource utilization rate, the I/O and memory of such as different mode are deposited Take and the program of network usage) etc..If so, then can according to one or more such factors to specific user and/or Its program is grouped (such as automatically), and these factors also act as selection computing system to perform the constraint bar of specific program Part and/or preference.Exemplary data center 170 also includes may include multiple interconnection device (not shown) (such as converters, side Edge router and core router) internal network 172, and be connected to internal network 172 computing system 175 and 182, PESCMM modules 160 and PESSM modules 180.Each host computing system 175 and other computing systems 182 can be with various sides Formula is set, including by being grouped in the frame of shared shared bottom plate or other connected mediums.It is also possible to use one Or multiple computing system (not shown) come it is each in execution module 160 and 180.

The PESSM modules 180 and PESCMM modules 160 of diagram implement it is at least some in the technology, to manage It is more fully described using computing system 175 and 182 come configuration processor in multigroup calculate node for providing, such as other places.When When selecting specific calculation node to perform one or more programs of user, in some embodiments, PESSM modules can pass through Interacted to out with other manager components of the execution of the program of VM manager components or the control selected calculate node Begin perform those programs, or can in selected calculate node direct configuration processor.Various calculating systems can be used in PES user System, such as computing system 190 or 192, or the computing system at place of one of other data centers 198 with PESSM modules 180 to carry out Interaction.

It is to be understood that Figure 1B data center is merely provided for illustrative purpose, and in other embodiments Program execution service can be otherwise provided and other softwares perform service.For example, data center 170 can be used on the contrary Outside one or more of the other computing system, the computing system at such as computing system 190,192 or data center 198 are come PESSM modules 180 and/or PESCMM modules 160 are provided.

Fig. 2A shows one group of example calculation section to providing the one or more programs for being used to perform example user The example for the technology that point is managed, the skill that can be such as implemented automatically by the embodiment of PESSM modules and/or PESCMM modules Art.Specifically, in this example, specific user (hereinafter referred to as user UUU and be not shown in fig. 2) has started to use one The multiple calculate nodes of group are come to represent the duplicate that the user each performs indicated program, such as use as calculate node is substituted The service received request provided by the configuration processor is handled (for example, to balance the service in the multiple of the whole group Calculated load in calculate node).As shown in timeline coordinate diagram 210, user has requested that offer calculates section in time T1 Point group, and specify initial required calculate node quantity 215a for 8 calculate nodes of the group.Information 250 is to each user The trigger instruction of definition, user specify in such as initial request to calculate node group.In addition, timeline coordinate diagram 205 Show on will be tracked for calculate node group and by the two of the performance characteristics whether being satisfied for determining trigger 250 The information of kind example types, the described information CPU overall average utilization rate 205a including calculate node group and calculating in this example The network bandwidth overall average utilization rate 205b of node group.

Event E1 during in response to the corresponding time T1 of the user received the request with starting offer calculate node group, Exemplary PES (not shown) starts the meter for initially including eight calculate nodes according to initial required calculate node quantity to user Operator node group.In addition, the calculate node quantity 225 of the offical record of calculate node group is similarly set to eight calculate nodes. However, as shown in timeline coordinate diagram 210, eight calculate nodes are not actually immediately available, since it is desired that one section Time provides these calculate nodes and it is can be used as a part for calculate node group, including makes journey by PES or user Sequence duplicate performs on each in these calculate nodes.Specifically, after the initial time after elapsed time T1, calculate The program executive capability of node group changes C1 255, and the change terminates in time T1 in whenabouts T2, and It is and corresponding with first four in available eight calculate nodes.Therefore, the actual calculate node for calculate node group is followed the trail of Quantity 220 increases to 4 in the time from 0.In addition, simultaneously or shortly after that, timeline coordinate diagram 205 shows, according to the group In can be started to follow the trail of CPU overall average utilization rate 205a and network bandwidth overall average utilization rate 205b with the operation of calculate node Performance characteristics.

In this example, PES (or other third party systems) is supervised in a manner of substantially continuous to this group of calculate node Survey so that carry out the information of retention property characteristic 205a and 205b and actual calculate node quantity 220 in a manner of newest.So And in this example, the dynamic modification of at least some of type periodically only is carried out to the calculate node quantity of calculate node group, such as To polymerize the modification through request of at least some of type during polymerization period 260, and with respectively required, actual and just Coordinating Activity is carried out at the end of the polymerization period between the calculate node quantity 215,220 and 225 of formula record.Therefore, first During polymerizeing period 260a, change 255 outside the calculate node quantity amount of calculate node group.For example, four calculating before making After the available change C1 of node, the follow-up change C2 that terminates in whenabouts T3 and the part that can be used as calculate node group Three additional calculations nodes it is corresponding.

However, in this example, such as hardware problem existing for the calculate node due to initially selecting (or conversely other In situation, because in time T1, only 7 calculate nodes can be used in calculate node group, wherein once the 8th calculate node with After can use, just its dynamic is added), the 8th calculate node of initial request can not can use in time.Therefore, event E2 is shown 265 occur after change C2 soon (during in whenabouts T4), wherein PES terminate the 8th calculate node originally (if Need) (if for example, it is frozen in an intermediate state), and start to provide the 8th replacement calculate node.Such as reference picture 2B is discussed in more detail, in this example, when PES has caused with adding the 8th initial calculate node corresponding time T1 Change C10a, but change C10a fails by having added and available reality the 8th calculate node is completed, therefore becomes Change C10a not embody in the actual calculate node quantity 220 of timeline coordinate diagram 210, also show in fig. 2 not otherwise Go out.On the contrary, in this example, event E2 is divided into simultaneously or nearly that simultaneous two different event E2a and E2b are not ( It is separately shown).Specifically, in this example, PES records and failed the 8th of correct initialization (such as in fixed time limit) Event E2a during the corresponding time T4 of individual calculate node, and change C10b (not shown) when PES triggers time T4 automatically To terminate the 8th initial calculate node for failing correctly to initialize.In addition, in this example, initial the 8th calculates section The actual termination that point occurs due to event E2a is considered as individual case E2b during time T4 in itself, and individual case E2b is automatic Trigger and the 8th replacement calculate node is provided immediately.So that result caused by the change of the first event can be considered as causing separately in itself Such the link event and respective change result of a kind of second event of change are between track of events and respective change result Various benefits can be provided in correlation, such as other places discuss in more detail.Then, opened according to event E2b in time T4 Begin, and the change C3 255 terminated in time T5 makes actual calculate node quantity be changed into eight from seven, because the 8th Substitute the part that calculate node can be used as calculate node group.

In eight calculate nodes by way of expectations after an operating polymerization period 260a part of calculate node group, Another change C4 255 occurs for whenabouts T7, actual calculate node quantity 220, and the change is become not in other words by failure One in available calculate node promotes.Corresponding event E3 265 at about occurs with change C4, and wherein PES is terminated can not With calculate node (if desired), and optionally automatically begin to provide to substitute calculate node.Specifically, with similar to before this The mode discussed for event E2, event E3 are divided into simultaneously or nearly simultaneous two different things in this example Part E3a and E3b (not separately shown).Therefore, PES records the calculate node phase with having become unavailable after testing in this example Event E3a during corresponding time T7, and PES triggers activity during time T7 to terminate unavailable calculate node, example automatically Such as change C4 directly to cause.In addition, in this example, the termination that unavailable calculate node occurs due to event E3a is in itself It is considered as automatic in whenabouts T7 to trigger to provide the individual case E3b of replacement calculate node immediately, but in other implementations In scheme and situation, substituting any this offer of calculate node will be merely deferred until at the end of period 260a is polymerize on the contrary The Coordinating Activity H1 of progress.Then, in this example, change C5 255 terminates in whenabouts T9, and the change is by actual meter Operator node quantity is recovered to eight, and this is directly caused by event E3b, because the replacement calculate node can be used as calculate node group A part.In this example, the calculate node quantity 225 of offical record is not updated temporarily with corresponding to change C4 and C5, Do not update with corresponding to previous change C1-C3, but in other embodiments, the calculate node quantity of offical record may be updated 225 to reflect some or all of such changes, such as continuously or repeatedly to keep the calculate node quantity 225 of offical record In the consistent state of the actual calculate node quantity 220 with being updated.In this example, when polymerizeing remaining of period 260a In the change of other calculate node capability availabilities or event do not occur, including all triggers 250 specified are not satisfied, and And the user instruction that dynamic is specified is not received.Therefore, in the time T11 at the end of the period 260a, it is contemplated that first group Coordinating Activity H1, but without any activity, because current desired, reality and the calculate node quantity 215 of offical record, 220 and 225 match at eight calculate nodes respectively.If do not carry out replacing unavailable calculate node during period 260a is polymerize Change C5 (as shown in the example), then after the polymerization period, the change on the contrary can be as the one of Coordinating Activity H1 Part is caused, to replace the unavailable calculate node at the time (for example, being asked during being incorporated in polymerization period 260a Or caused any other dynamic availability change).

However, during the second polymerization period 260b, there occurs other events.Specifically, event E5 265 is sent out first It is raw in whenabouts T16, so as to corresponding with automatically determining of making of PES, i.e., by improving CPU overall average utilization rates 205a is satisfied trigger TR-1 250a, as in timeline coordinate diagram 205 by CPU overall average utilization rate 205a lines First black ellipse illustrated in.For 12 through calculate node quantity 215c needed for the whole of request (or nothing By current desired calculate node quantity how, the required calculate node quantity that can ask to be updated is arranged to 12), touch Hair device TR-1's meets that situation has triggered the request that required calculate node quantity 215 is increased to 4 calculate nodes.Similarly, exist After other extra time, next event E6 265 occurs in whenabouts T18, so as to determining by carrying High network bandwidth overall average utilization rate 205b is corresponding be satisfied trigger TR-N 250c, in timeline coordinate diagram 205 By illustrated in the black ellipse on network bandwidth overall average utilization rate 205b lines.For ten all required calculating through request For number of nodes 215d (or regardless of current desired calculate node quantity, the required calculating that will be updated can be asked Number of nodes is arranged to ten), trigger TR-N's meets that situation has triggered required calculate node quantity 215 is increased into 2 meters The request of operator node.After by shorter extra time, event E4 265 occurs in whenabouts T19, wherein for 11 through for calculate node quantity 215b needed for the whole of request (or no matter current desired calculate node quantity such as What, the required calculate node quantity that can ask to be updated is arranged to 11), the user related to calculate node group provides The dynamic that required calculate node quantity 215 is increased to 3 calculate nodes specifies request.For example basis it can notice CPU overall averages Utilization rate 205a is the user that is increasing etc. of total calculated load in higher, calculate node group to make the request.

Finally, shortly before polymerization period 260b terminates, the extra C6 that changes occurs in whenabouts T20, the change One in this group of calculate node become unavailable in other words by failure promotes.Corresponding event E9 and change C6 is at about Occur, wherein PES terminates unavailable calculate node (if desired).In this example, but PES is not to immediately begin to offer to replace For calculate node, but decide to wait for starting (for example, root when the second group of Coordinating Activity H2 that will be carried out is in time T21 There is provided according to a small amount of time remaining before time T21, according to the such delay for substituting calculate node etc., the delay is to make The default-action for any calculate node that used time becomes unavailable) because will likely be reduced according to those Coordinating Activities The quantity of calculate node in calculate node group, and without the replacement calculate node.In other embodiments, PES is opposite Ground, which can immediately begin to provide, substitutes calculate node (for example, based on the replacement for not postponing unavailable calculate node under any circumstance； Based on not postponing the replacement of unavailable calculate node in this case (because required calculate node quantity is as Coordinating Activity H2's A part and may increase rather than reduce)；Based on do not postpone in this case unavailable calculate node replacement (due to it is other because Element, such as user are paid to eight calculate nodes before later time T3)；Deng).Specifically, with similar to The mode discussed previously for event E2 and E3, event E9 are divided into simultaneously or nearly simultaneous two different events E9a and E9b (not separately shown).Therefore, PES records relative with the calculate node become unavailable after testing in this example Event E9a during the time T20 answered, and PES triggers activity during time T20 to terminate unavailable calculate node, example automatically Such as change C6 directly to cause.In addition, in this example, the termination that unavailable calculate node occurs due to event E9a is in itself It is considered as individual case E9b during whenabouts T20, the event, which triggers to be used as substituting by the additional calculations node of the group, calculates section The request of point, such as so that required calculate node quantity 215 to be maintained to the requirement 215a of eight calculate nodes.In the example In, event E9b request is handled in a manner of similar to event E4-E6, the request is merely deferred until when when pre-polymerization The Coordinating Activity H2 carried out at the end of section 260b, but in other embodiments and situation, can immediately begin to substitute meter on the contrary This offer of operator node.In addition, in this example, do not updated in a manner of similar to being described previously for change C4 and C5 The calculate node quantity 225 of offical record is corresponding to change C6, but in other embodiments, to may be updated the meter of offical record Operator node quantity 225 is to reflect such change.

Therefore, at the end of the second polymerization period 260b, start Coordinating Activity H2, and can cause in this case to meter The dynamic modification of operator node group.Specifically, PES in this example will be various through request with event E4, E5, E6 and E9b The corresponding modification polymerization through request of required calculate node quantity 215b, 215c, 215d and 215a, and determine to eight elder generations Calculate node quantity 215a needed for preceding makes the dynamic quantity modification of polymerization, while the dynamic quantity modification polymerizeing is in this example Four additional calculations nodes (for example, based on using maximum in the quantity modification through request) are added, so as to corresponding to ten Two current desired calculate node quantity 215e updated.In other embodiments, otherwise can determine to polymerize Dynamic quantity modification, such as changed with the dynamic quantity of selective polymerization to keep previously necessary calculating according to event E9b Number of nodes 215a (for example, so as to cause to increase a calculate node from current actual calculate node quantity), with using thing Minimum value in the part E4-E6 modification of the quantity through request is (for example, so as to cause from current desired calculate node quantity increase Two calculate nodes), the average value changed with the quantity through request using event E4-E6 is (for example, so as to cause from current institute The calculate node quantity needed increases by three calculate nodes), the polymerizing value changed with the quantity through request using event E4-E6 (for example, so as to cause to increase by nine calculate nodes from current desired calculate node quantity), to be asked using event E4-E6 warp The limit priority for the quantity modification asked is (for example, so as to cause to increase by three calculating sections from current desired calculate node quantity Point, with the proviso that the trigger for example compared to event E5 and E6 meets situation, E4 user instruction is considered as with higher prior Level), with the modification or the modification of last time request asked for the first time in the modification of the quantity through request using event E4-E6 (for example, so as to cause to increase by four or three calculate nodes respectively from current desired calculate node quantity) etc..Use wherein Family command event compared to trigger meet event have in some embodiments and situation of higher priority (if for example, with Family instruction can cover any dynamic modification through request for meeting event from trigger all the time), PES can also prevent other triggerings Device meets that event occurred during the polymerization period after receiving user instruction event, such as (or exhausted to ignore in this example It is uncertain) occur meeting event for event E4 to receive any trigger after user instruction.In addition, in the example In, in Coordinating Activity H2, the currently practical and calculate node quantity of offical record 220 and 225 calculates section at seven and eight It is respectively different at point.Therefore, the part as Coordinating Activity H2, PES start to provide five additional calculations to calculate node group Node, seven current actual calculate node quantity are increased into 12 required calculate node quantity newly updated, and The calculate node quantity 225 of offical record is further updated to meet 12 required calculate node quantity newly updated.Therefore, In this example, the capability availability change of 5 calculate nodes is caused by the following manner indirectly：Replaced according to event E9b A calculate node becoming unavailable due to change C7, and increase with from gathering determined by event E4, E5 and E6 Close quantity and change 4 corresponding additional calculations nodes.

During third polymerization period 260c, other event and calculate node capability availability changes further occur.Tool Say, change C7 terminates in whenabouts T22, wherein currently available calculate node quantity adds five to altogether ten body Two calculate nodes, to reflect five additional calculations nodes that its availability starts in time T21, and actual calculate node Thus quantity 220 is updated.As shown in timeline coordinate diagram 205, CPU overall average utilization rate 205a and network bandwidth overall average profit Reduced with rate 205b changing after C7, wherein CPU overall averages utilization rate 205a declines rapidly.Specifically, in the example In, CPU overall average utilization rates 205a is finally brought down below 20% threshold value corresponding with trigger 250b specified value, from And cause event E8 that (including determine trigger TR-3250b be satisfied) occurs, as total by CPU in timeline coordinate diagram 205 Illustrated in second black ellipse on average utilization 205a lines.For ten through calculate node quantity needed for the whole of request For 215f (or regardless of current desired calculate node quantity, the required calculate node quantity that will be updated can be asked It is arranged to ten), trigger meets that situation has triggered the request that required calculate node quantity 215 is reduced to 2 calculate nodes.

Finally, before polymerization period 260c terminates, the extra C8 that changes occurs in whenabouts T28, and the change is by losing One in this group of calculate node that effect becomes unavailable in other words promotes.Corresponding event E10 is at about sent out with change C8 Raw, wherein PES terminates unavailable calculate node (if desired).In a manner of similar to for change C6, PES is in this example Selection is waited when the 3rd group of Coordinating Activity H3 is in time T31, rather than immediately begins to substitute unavailable calculate node (example Such as, because event E8 allows to or it is likely that in calculate node group hereafter the requirement of calculate node can be reduced), But in other embodiments, PES, which can immediately begin to provide on the contrary, substitutes calculate node, specifically, with similar to before this For the mode described in event E2, E3 and E9, event E10 is divided into simultaneously or nearly that simultaneous two not in this example Same event E10a and E10b (not separately shown).Therefore, in this example, PES is recorded and after testing become unavailable Event E10a during the corresponding time T28 of calculate node, and PES triggers activity during time T28 can not to terminate automatically With calculate node, such as directly to cause change C8.In addition, in this example, unavailable calculate node due to event E10a and The termination of generation is considered as individual case E10b during whenabouts T28 in itself, and the event triggers the additional calculations section of the group Point is used as the request for substituting calculate node, such as so that required calculate node quantity 215 to be maintained to the institute of 12 calculate nodes Need quantity 215e.In this example, event E10b request is handled in a manner of similar to event E9b, the request is delayed by Until by the Coordinating Activity H3 carried out at the end of pre-polymerization period 260c, but in other embodiments and situation, conversely Ground can immediately begin to substitute this offer of calculate node.In addition, in this example, not with similar to previously for change C4- Mode described in C6 updates the calculate node quantity 225 of offical record with corresponding to change C8, but in other embodiments, The calculate node quantity 225 of renewable offical record is to reflect such change.

Therefore, at the end of third polymerization period 260c, start Coordinating Activity H3, and calculate node group can be caused to occur Change.Specifically, PES is in this example by with having occurred and that the event during period 260b (is only thing in this example Part E8 and E10b) it is corresponding through request modification polymerization, and determine to 12 previously necessary calculate node quantity 215e The dynamic quantity modification of polymerization is made, the modification reduces two calculate nodes in this example, so as to corresponding to ten institutes The current desired calculate node quantity 215g of renewal.In addition, in Coordinating Activity H3, the currently practical and calculating section of offical record Point quantity 220 and 225 is respectively different at 11 and 12 calculate nodes.Therefore, the part as Coordinating Activity H3, PES triggers 12 current formal calculate node quantity according to the currently practical calculate node ability of 11 calculate nodes Change, to reach ten current desired actual calculate node quantity, so as to which one of existing calculate node is saved from calculating Removed in point group (for example, optionally to terminate in the calculating section removed after some or all of actions for completing to have started to Configuration processor on point, and so that the calculate node is available for other users to use in the future).Therefore, in this example, in the time The capability availability change for removing one of existing calculate node during T31 is caused by the following manner indirectly：Terminate on event E10b one group of calculate node, and request reduce 2 calculate nodes corresponding with event E8.Further renewal is formal by PES The calculate node quantity 225 of record is to meet ten required calculate node quantity newly updated.After time T31 soon, most Change C9 terminates in whenabouts T32 eventually, wherein currently available calculate node quantity reduces one to ten altogether meter Operator node, to be reflected in the calculate node for starting to remove from calculate node group during time T31, and actual calculate node quantity Thus 220 are updated, in other embodiments, when deciding to do the change, change C9 substantially can occur immediately Time T31, such as with the proviso that immediately by calculate node to be removed from calculate node group it is other activity in exit, or even The calculate node removed temporarily performs and available for when being worked on.

In addition, though shown in this example Coordinating Activity H1, H2 and H3 occurred at single time point, but it should reason Solving some or all of Coordinating Activities can actually occur in a period of time, and can also be other with continuing for some time Effect.For example, at least some embodiments, by the PES program executive capability to calculate node group triggered some or All changes can produce the temporary locking phase that may not allow at least some other types of events or change.This locking can be caused PES- instruction program executive capability change may include for example as Coordinating Activity a part come caused by program perform energy Power increases and/or reduces (for example, add new calculate node, remove existing calculate node etc.), and/or determines (example in response to PES Such as, calculate node failure, receive the trigger that user instruction, user specify meet situation etc.) and the program that triggers immediately is held Row capacity variation.Such locking can have various types of duration (for example, until the result specified or generation, such as directly It has been made available by the calculate node added；The duration specified, the calculate node such as added are made available by flat Equal or expeced time；Deng), and in some embodiments can be different according to the type of the PES changes triggered.Herein During class locks, event or the change of at least some of type may not be allowed, such as not in during the Lockout Duration The trigger that user specifies is satisfied (or meeting situation by ignoring any such trigger), and/or not in the locking Receive user instruction (or by ignoring any such user instruction) during duration.In addition, in some embodiments, with The related user of calculate node group can similarly specify the cooling phase to be operated with locking cooling phase similar mode, such as immediately Locking or the cooling phase that specified time amount at other times occurs on the contrary.Such as locking, during cooling, may not allow The event of at least some of type or change, such as the trigger to be specified not in cooling period user are satisfied and (or passed through Ignore any such trigger and meet situation).It is to be understood that in other embodiments, user and/or PES can be with other Mode controls the modification to calculate node group.

Therefore, so, PES operations are supplied to the program executive capability of user by one group of calculate node to manage, including with Various dynamic modifications are made to the calculate node group according to various situations.It is to be understood that the event shown in Fig. 2A and change It is merely provided for carrying out schematical purpose, and the PES actual event, change and other operations are in other embodiments It is possible different with situation.

Fig. 2 B are shown for causality information to be attributed into the calculate node number that reference picture 2A before this discussed automatically The example of the technology of amount dynamic modification, the technology that can be such as carried out automatically by the embodiment of PESSM modules.Specifically, scheme 2B shows two instance database list data structure of the storage with some corresponding information in information shown in Fig. 2A, wherein The exemplary meter that Fig. 2 B storage of example table 280 and Fig. 2A exemplary computing node group (being referred to as " the 1st group " in Fig. 2 B) occur Operator node capability availability changes relevant various information, and Fig. 2 B storage of example table 290 and Fig. 2A example calculation The relevant various information of (the 1st group) exemplary event occurred of node group.

Example table 280 include respectively correspond to one of the exemplary variations C1-C10 that reference picture 2A is discussed each row or Item 285a-285k, it illustrated therein is each column or row 280a-280x of each row.Specifically, in this example, each row is included only One identifier (" ID ") 280a, ID 280b that is applicable calculate node group corresponding with change, the class of program executive capability change The instruction 280d for the expected results that type 280c, program executive capability change, the various details 280e on change, the beginning of change (it is in this example base to end time 280f and 280g, the polymerization period 280h related to change in other words that changes The polymerization period mentioned by Coordinating Activity carried out at the end of the period is being polymerize), change-event close knot ID 280x and optionally Various other information.As an illustrative examples, row 285a corresponds to the 1st group of change C1, and change C1 corresponds to the 1st group Calculate node quantity change, the change be related to increase by 4 calculate nodes and during period H1 is polymerize in time T02 when Terminate.Other rows include similar information.

Example table 290 includes respectively correspond toing one of the exemplary event E1-E10 described in reference picture 2A each row or item 295a-295m, it illustrated therein is each column or row 290a-290x of each row.Specifically, in this example, each row includes unique Identifier (" ID ") 290a, ID 290b that is applicable calculate node corresponding with event, the type 290c of event, on event The information 290d in source, the time 290e of event, generation event or perhaps the polymerization period 290f related to event are (in the reality Example middle finger is based on the Coordinating Activity carried out at the end of the period polymerize), change-event close knot ID 290x and optionally various its Its information (for example, specific user related to the user instruction received).As an illustrative examples, row 295h corresponds to 1st group of event E4, event E4 correspond to the user instruction received during the time T19 during period H2 is polymerize, and this refers to Order asks the 1st group of required calculate node quantity to increase by 3 calculate nodes.Other rows include similar information.

In Fig. 2 B example, change-event of table 280 and 290 is closed knot id information 280x and 290x and reflected by attribution The causality information of relation between reflection change and event.Specifically, in this example, if in table 280 and 290 The hand-manipulating of needle knot id information 280x and 290x is closed to change-event and shared common value, then that reflects corresponding event and change Between the causality by attribution.As an example, as reference picture 2A is discussed before this, event E3b, which corresponds to, provides change For the replacement calculate node of disabled calculate node, the calculate node can be directly attributed to correspond to thus by calculate node Added to the change C5 of the group.Therefore, row 295e (corresponding to event E3b) and row 285g (corresponding to change C5) share jointly Close knot identifier.

On the contrary, the change C7 corresponding with five calculate nodes of addition started during Coordinating Activity H2 is without can It is directly attributed to the individual event of the change.Specifically, event E4, E5 and E6 each asks to enter the 1st group Mobile state modification, These are dynamically changed aggregated and are provided commonly for promoting to add four in five calculate nodes for change C7.Thus, OK The shared common pass knot identifiers of 295f-295h (corresponding to event E4-E6) and row 285i (corresponding to change C7).In addition, In Fig. 2A example, it is added as changing one of C7 five calculate nodes of a part as because change C6 becomes not The substitute node of available calculate node, start simultaneously at the replacement calculate node corresponding to event E9b.Therefore, row 295j is (corresponding In event E9b) and row 285i (correspond to change C7) also share identical and close knot identifier jointly.In other embodiments, If individually start to provide replacement in event E9b by providing four additional calculations nodes corresponding to event E4-E6 Calculate node, such as to replace unavailable calculate node immediately, then the respective change for substituting calculate node will be in the period The 260b and Coordinating Activity H2 thus carried out occurs before terminating, and by table 280 from event E9b and sharing different phases The extra change that knot identifier should be closed individually is shown.In addition, though five calculate nodes added for change C7 Shown in a manner of polymerization in the single file of table 280, but in other embodiments, each calculate node added can be Represented in the single row 285 of table 280, and if so, it, which each shares identical, closes knot identifier N7, pass knot mark Symbol N7 changes C7 unique row 285i currently for polymerization and shown.

In addition, in this example, change has been followed the trail of in table 280, these changes correspond not only to refer to based on dynamic subscriber The dynamic modification of the calculate node quantity for the user's trigger for making and/or being satisfied, the unexpected change also based on calculate node quantity Change (for example, being become unavailable in other words because calculate node fails).Such change is detected based on monitoring activity, and by It is shown as triggering the event (such as provide and substitute calculate node) additionally changed, but in other embodiments, can be otherwise It is handled, such as does not follow the trail of such change and/or the replacement activity that system starts is not considered as event.Although in addition, Change in table 280 and 290-event, which closes knot information, pair can not be directly attributed to one or more corresponding events (for example, drawing immediately Send out those change events) change and one or more corresponding events can be attributed to indirectly (for example, for example in the Coordinating Activity phase Between the event that condenses together and cause those to change jointly) change make a distinction, but in other embodiments, one can be entered Step tracking this type of information.

As it was previously stated, the attribution of responsibility changed the specific program executive capability dynamic of calculate node group can provide various benefits Place, including to related to calculate node group user's offer why the explanation that can be changed.May also be responsive in from user or its All kinds of inquiries received at its source produce and/or using such attribution of responsibility information, these inquiries such as on identification which (multiple) event is that the specific program executive capability for causing the availability of one group of one or more calculate node to indicate is repaiied a bit Which change or request the reason for other changes and/or on (multiple) program executive capability modification or other calculate node groups The request as caused by the event of one or more instruction of (multiple) change in availability.Reference picture 2B is discussed, in table 280 and 290 The pass knot information shown provides a kind of mechanism for being used to following the trail of and providing attribution of responsibility information.For example, in Fig. 2A with change For changing corresponding 5 calculate nodes of addition of C7, user may wonder with the addition of 5 calculate nodes why (for example, especially It is the user instruction according to the event E4 of 3 calculate nodes of addition).Tie information by using the pass that is shown in Fig. 2 B, PES or its Its system can be easy to automatically generate the readable explanation of people.For example, in response to the addition four corresponding on the change C1 with Fig. 2A User's request of the reason for individual calculate node, PES or other systems can for example indicate herein below：" when change C01 is by time T1 Event E01 directly cause.Event E01 be from user UUU with start provide one group of 8 calculate node request ".The information Can so it produce：Correspond to event in table 290 by using the pass knot information 280x for corresponding to change C1 in row 285a to identify E1 row 295a, and extracted in a desired manner from row 285a and 295a with formatted message (for example, to be asked based on user Or previous User Preferences form, with form based on PES default values etc.).Similarly, in response to referring on performing user Make E1 and asked with starting to provide the user of eight calculate nodes of the group, PES or other systems can for example indicate herein below：" when Between T1 when event E01 directly cause change C01, C02 and C03.Change C01 as 4 calculate nodes of addition, it is in time T1 Start and terminate in time T2.Change C02 as 3 calculate nodes of addition, it starts in time T1 and in time T3 When terminate.Change C03 as 1 calculate node of addition, it does not terminate in time T1 ".As another example, ring User's request of the reason for Ying Yu five calculate nodes of addition corresponding on the change C7 with Fig. 2A, PES or other systems Herein below can for example be indicated：" change C07 is by occurring in period T11 between event E05, E06, E04 and E09b during T21 Connect and cause.Event E05 is the request of 4 additional calculations nodes for meeting situation based on trigger TR-1.Event E06 be based on The request of trigger TR-N 2 additional calculations nodes for meeting situation.Event E04 is to be carried based on the user from user UUU For the request of 3 additional calculations nodes of dynamic instruction.Event E09b is the automatic end based on unavailable calculate node in the group The request of 1 replacement calculate node only ".As the supplement or replacement to such text string, attribution of responsibility information can also be each Kind of other forms autoreport (for example, with form, chart etc.) and produced with regular or other predetermined ways.Should It is understood that in other embodiments, such attribution of responsibility information can be produced and used in a manner of various other.

It is to be understood that the information of the event and change on being shown in Fig. 2 B is merely provided for carrying out schematical mesh , and for stored information, the storage of this type of information can be come in a manner of various other in other embodiments Carry out.In addition, in other embodiments, PES can store the information of the various other types on user and calculate node group, Such as to provide storage on user-defined trigger, the performance measure information on monitoring, the letter on user account etc. The add list of breath.

In addition, Fig. 2A and 2B previous examples are provided for carrying out schematical purpose, and other embodiments can be with Various modes are different from these examples.Although for example, in these examples, program executive capability according to the quantity of calculate node come Measurement and modification, such as with the proviso that various available calculate nodes are considered as equivalent (for example, with equivalent computing resource), but Other embodiments can be provided, wherein various available calculate nodes can be (such as different disposal abilities, interior with different qualities Storage, platform specification etc.) different type, and/or wherein come in a manner of different from calculate node quantity tracing program execution Ability.In some such embodiments, various requests may include the instruction of one or more certain types of calculate nodes, institute State calculate node to be used to be selected in multigroup calculate node of the execution program related to the request, and those requests are only It can be realized in the calculate node of corresponding specified type.

In addition, at least some embodiments, PES or other systems can be also carried out as the multigroup calculate node of management The other types of activity of a part.For example, as it was previously stated, PES or other systems can be determined in each time from calculate node Calculate node is added or removed in group, and each time includes as follows：(rung during the Coordinating Activity carried out at the end of polymerizeing the period One or more triggers that Ying Yu is satisfied during the period and/or the user instruction received during the period)； In response to designated or determining there is the user instruction of immediate effect or trigger to meet any time of situation；Responding In the automatic movable of PES or other systems for example to replace the calculate node of failure and/or termination and to remove current operation banned Any time of calculate node only；Deng.In at least some embodiments, PES or other systems can also be it is determined that at least one Consider other factorses during the exact time of a little such calculate node group modifications.For example, it will be responsible for making for the given period in user It is such in the case of with the calculate node of given quantity (for example, having collected expense of the X calculate node at next hour) Information can be used for the time for determining the modification of at least some of type on calculate node group.If PES or other systems determine The quantity of calculate node in the group is reduced below X, then PES or other systems can be determined calculate node quantity actually It is reduced below before X, waits at the end of close to given period or given period (for example, being collected the charges to user Hour at the end of).Similarly, if one group of calculate node fails (for example, close when close to progress new Coordinating Activity At the end of by a period of time during the calculate node quantity modification polymerization through request), then PES or other systems can be determined to reality The number of nodes of border number of nodes and optional offical record is updated, and to reflect the failure, but need not immediately begin to add Add replacement calculate node-so, if it is determined that calculate node quantity modification of the polymerization through request can will during Coordinating Activity The calculate node quantity of the group reduces one or more calculate nodes, then the calculate node to fail can be used as the such of reduction Node, and the execution calculate node of the nonterminal group.

In some embodiments, PES or other systems can manage the multiple inhomogeneity carried out to calculate node group simultaneously The modification of type.As an example, the calculate node of single opening position can be used calculate node group management current desired Calculate node quantity, but user can be determined as calculate node group specify Second Type yardstick so that calculate node in the group The required subset specified be located at the different second places.If so, PES or other systems are operable by by a manner of various To meet the desired value of the second yardstick, various modes are included by the way that any new calculate node is progressively added into the second place Desired value of any existing calculate node until realizing the second yardstick is progressively removed in group and from the group at first position, or Person terminates the existing calculate node in the group at first position so that replacement calculate node can be made to be added to the second place immediately Group in.It is such progressively add and/or remove can in a manner of other places discuss in more detail in any mode trigger, Including the trigger for replacing unavailable calculate node, being specified in response to the user instruction dynamically specified and/or the user being satisfied To change calculate node quantity etc..In addition, though calculate node quantity and position are in this example to be simultaneously balanced, but can be with class As mode come carry out the change of various other types (for example, for example according to have different correlated measures computing resource not Same type by existing calculate node from the first type change be second of type).Although in addition, by changing calculate node number Amount has carried out the modification of program executive capability in some instances, but in other embodiments, such ability modification can be by changing Become the program executive capability of one or more calculate nodes in the group to carry out (for example, by using with more or less one kind Or the second calculate node of polytype correlation computations resource replaces the first calculate node, by as one of the group The amount of the available one or more computing resources of a node in the calculate node divided is modified).

As it was previously stated, PES can be provided and using types of functionality in each embodiment, and these functions can be with various Mode provides.For example, in some embodiments, multiple calculate nodes, institute can be may include from the program executive capability that PES is obtained State calculate node and be used to representing user and carry out configuration processor, such as by via one or more networks or can be between the computers Transmit multiple physical computers of other data exchange mediums interconnection of data.At least some in these computers can be at some Each include performing the enough calculating related resource of multiple programs in embodiment simultaneously (for example, enough writeable internal memories, non- Volatile storage, cpu cycle or other CPU usages measurement, network bandwidth, swapace etc.), and in these computers At least some that multiple virtual machine calculate nodes can be each provided in some such embodiments, the virtual machine calculate node is each One or more programs are performed from different users can be represented.In addition, in each embodiment, PES can represent multiple use Family performs each class method.For example, this class method for representing user to perform may include one or more operating systems, application (for example, server and/or other software applications), utility program, program library etc..In addition, at least some embodiments, this Class method may include executable software image, such as virtual machine image, and it can in one or more virtual machine calculate nodes Start loadable, and each may include operating system software, the software for one or more application programs in other words, And/or configuration information etc..
