Embodiment

As shown in Figure 1, the computational resource that Service Management in the grid computing environment 100 is used to use. grid computing environment 100 can be distributed separately with the calculating of execution application or a distribution type computational resource of data retrieval task. and computational resource comprises

computer equipment

12,14,16,18,20 use network 8 communicate by letter with 22. computer equipments. and application has scalable calculation requirement. for example, use the computer equipment 12 in the

grid computing environment

100,14,16,18,20 and 22 example application is an internet price configurator (configurator). and computer equipment 12 provides access to netwoks to pricing information via the web browser on the computer equipment that is connected to the internet to the user. and this web browser can be can displaying contents and/or carry out such as webpage, any application of the application of media file and program is such as Netscape

Microsoft Internet

And similar application.

In this example, the webserver on the computer equipment 12 provides the calculating parameter of each price that pricing information .IPC scheduler (dispatcher) 116 will calculate to send to respectively at the IPC server of carrying out on

computer equipment

12,14,16 and 18 120,122,124 and 126. because the webserver and the application flexibility on the internet to the user, and user's number can change. and this has just produced the dynamic calculation requirement to internet price configurator.Communication for service in IPC manager 118 and the grid computing environment 100, so that service can according to the internet fix a price that the dynamic calculation of configurator requires and the allocation and deallocation computational resource (for example,

computer equipment

12,14,16,18,20, processor in 22). the allocation and deallocation computational resource makes computer equipment 12 by this way, 14,16,18,20 and 22 are designated as general-purpose computational resources, and can just not be exclusively used in and handle the peak demand .

IPC manager

118 and 116 collaborative works of IPC scheduler that internet price configurator is used, so that IPC scheduler 116 can be visited the resource in (have access to) network 8.

The ability of the resource in this allocation and deallocation grid computing environment 100 make IPC manager 118 can be in " as required " in case the basis on location and use available computational resources. resource is positioned, IPC manager 118 just can use service in the grid computing environment 100 with IPC server 120,122,124 and 126 are installed to as application that .IPC scheduler 116 uses by people such as Tuecke at open grid service infrastructure (Open GridServices Infrastructure on the computer equipment in the grid computing environment 100, OGSI) Web Service Definition Language that defines in 1.0 versions (WebService Definition Language, WSDL) IPC scheduler 116 and IPC server 120 are managed and exchanged to interface, 122, information flow between 124 and 126. for example, OGSI WSDL interface can be used to the calculating parameter that calculates that is used to fix a price is sent to IPC server 120 from IPC scheduler 116,122,124 and the 126.OGSI WSDL interface result that can also be used to finish from IPC server 120,122,124 and 126 send back IPC scheduler 116. is incorporated herein by reference .OGSI WSDL interface with OGSI 1.0 versions and makes it possible to grid computing environment 100 and carry out controlled such as the application of internet price configurator, have (fault-resilient) of error recovery capabilities and the management of safety.

Use IPC server 120 at IPC scheduler 116,122,124 and 126 when carrying out users' calculating, service monitoring operation IPC server 120 in the grid computing environment 100,122,124 and 126, the utilization of resources of the computer equipment in the grid computing environment 100. service also utilizes this information to send to IPC manager 118. according to the comparison between utilization requirement and current resource load, IPC manager 118 can dynamically notify the service in the grid computing environment 100 so that be IPC server 120,122,124 and 126 distribute more resources, perhaps remove Resources allocation, so that make the utilization of resources in the grid computing environment 100 remain on the level of expectation.

Grid managers 152,154,156,160,162 and 164 reside in computer equipment 12 respectively, 14,16,18, in 20 and 22. in grid computing environment 100, grid managers is to having direction relations (directional relations), this direction relations is categorized as a grid managers higher level (superior) of another grid managers. and grid managers can have superior relation more than one with other grid managers. for example, grid managers 152 has superior relation with

grid managers

154 and 156. and grid managers can also have inferior relation (inferiorrelations) more than one with other grid managers. by these hierarchical relationships, IPC manager 118 does not need the tabulation of all computer equipments in the accesses network 8, so that use the computational resource in the grid computing environment 100. only require IPC manager 118 can visit the network address of the computer equipment (for example moving the computer equipment 12 of grid managers 152) of an operation grid managers, and this grid managers utilize it and the relation that operates in other grid managers on other computer equipment to provide dereference to other computer equipment in the grid computing environment 100 to IPC scheduler 116.

Grid managers (for example 152,154,156,160,162 and 164) safeguard with first tabulation of all superior relation of other grid managers and with second tabulation of all inferior relation of other grid managers. each grid managers is all at transmission control protocol (TCP), the communication channel of all grid managers during for example above-mentioned OGSI WSDL interface maintenance of use is tabulated to these via network 8 on HTTP(Hypertext Transport Protocol) and the Simple Object Access Protocol (SOAP) " opening forever ". the communication channel of these tabulations and correspondence can be modified, to allow dynamically to reconfigure trellis stage during working time. this also allows dynamically to replace the fault grid managers in level. for example, with reference to Fig. 1, if grid managers 154 breaks down, then grid managers 152 is lost it to

grid managers

160 and 162 be connected. in this case, relation between the grid managers can be modified, it is new so that grid managers 152 has, superior relation with

grid managers

160 and 162. similarly,

grid managers

160 and 162 has new, inferior relation with grid managers 152.

As shown in Figure 2, design application start and handled 200, so that (for example using, internet price configurator) (for example at computer equipment, 12,14,16,18,20 or 22) go up before the execution, the essential resource that acquisition distributes in network 8. handle 200 and also guarantee: if similar application is attempted to start simultaneously on the same asset on the computer equipment, then these two or more application can not conflict or the phase mutual interference mutually. for example, for guarantee service quality (QoS), IPC manager 118 can require: IPC server (for example 120) is unique application of carrying out on the processor in computer equipment 14. in this case, if other is used on the processor of attempting simultaneously in computer equipment 14 and carries out, then Another Application will be disturbed.

Handle 200 and comprise that IPC manager 118 (or some other application) sends (202) requirement to computational resource, with inquiry grid managers (for example 154) thus determine in grid computing environment 100, whether there are the available resources that require coupling with these. the information about the resource in the computer equipment has been specified in these requirements, all numbers of processor as requested, desired those processors, primary memory and network speed utilize number percent. inquiry can also comprise that relevant this inquiry should be transmitted to which rank of the information of (in grid computing environment 100) level. handle 200 and comprise that grid managers 154 receives (204) these requirements.

For respond from IPC manager 118, to the inquiry of available resources, to handle 200 and comprise that grid managers 154 will require to mate (206) with the known resource of grid managers 154. these resources comprise by the resource (for example, processor) in the grid managers 154 direct computer equipments of managing 14.Current resource available and that meet the demands, that directly managed by grid managers 154 is added in the resource-query list of being safeguarded by grid managers 154.

Grid managers 154 also sends these inquiries to the grid managers 160 and 162 that has an inferior relation with grid managers 154.Handle 200 and comprise that grid managers 160 and 162 satisfies the requirement of being asked and grid managers 160 and 162 that can use and tabulations known resource (for example processor on the computer equipment 18,20) respond (208) this inquiry by sending to grid managers 154 respectively.These resource-query list of grid managers 160 and 162 known resources can also comprise by having the resource of the grid managers (not shown) management of inferior relation with grid managers 160 and 162.Grid managers 154 will add to from these resource-query list of the available resources of grid managers 160 and 162 in its resource-query list of the available resources that satisfy the requirement of being asked.Determine that there is at least one resource (for example, processor) in (210) in this resource-query list if handle 200, then grid managers 154 sends (214) to IPC manager 118 with this resource-query list.Otherwise, determine that (212) grid managers 154 and higher level's grid managers (for example, grid managers 152) have relation if handle 200, then grid managers 154 will send to (202) grid managers 152 to the inquiry of available resources.In response to this inquiry, grid managers 152 can not send it back unnecessary inquiry the grid managers 154 that has inferior relation with grid managers 152.

Handle 200 and comprise that the address of its corresponding grid managers in that grid managers 154 requires the tabulation of available resources and coupling, the network 8 sends (214) together.IPC manager 118 is selected resource (for example, the resource on the computer equipment 14) from this tabulation, and the resource on grid managers 154 request (216) the reservation computer equipments 14 of the resource on the Management Calculation machine equipment 14.If the resource on the computer equipment 14 still can be used for reserving (218) and reserving successfully, then grid managers 154 sends (220) reserved number to IPC manager 118.This reservation means and guarantees that IPC manager 118 has and distribute resource on the computer equipment 14 that asked, in the grid computing environment 100 to it.Grid managers 154 use the independent processing thread of carrying out to handle to come from such as the application of IPC manager 118, to the inquiry of available resources.Like this, grid managers 154 uses signal lamps (semaphore) to guarantee that identical resource (for example, processor) can not ask identical resource simultaneously and be assigned with a plurality of reserved number owing to different application.

If the resource in the computer equipment 14 that grid managers is determined to be asked can not be used for reserving and reserving failure, then this next one available resources are reserved in next available resources in 118 selective listings of IPC manager and request (216).If IPC manager 118 receives herd number and does not have expired (222) from sending the time-out time (timeout) that this herd number begins to measure, then the resource of IPC manager 118 in computer equipment 14 starts (224) IPC server 122 on the processor.By transmitting reserved number to grid managers 154 and application file begins to start IPC server 122, and grid managers 154 reads this application file so that install and carry out IPC server 122 on computer equipment 14 subsequently.

As shown in Figure 3, handling 250 computer equipments (for example 14) in grid computing environment 100 goes up to install and (for example uses, IPC server 122) so that sets up available resources for this application, use this available resources, and to remove or unload this application so that discharge described resource be that later application is used when no longer needing this resource.Handle 250 and comprise that IPC manager 118 transmits (252) and comprises the code of IPC server 122 and for how installing, customize, follow the tracks of this application and remove the application file of the indication of these application from computer equipment 14, so as carry out this applications afterwards grid managers 154 can make computer equipment 14 turn back to virgin state.

IPC manager 118 for example uses file transfer protocol (FTP) (FTP), HTTP(Hypertext Transport Protocol) or (Network Attached Storage, file copy NAS) sends application file to computer equipment 14 as the single file such as the zip file of compression from network attached storage.In this zip file relevant for installing and the information of customized application IPC server 122.Expression that this information is by little executable program or extending mark language (XML) document---it is extracted and translation (254) by installation in the grid managers 154 and customization engine (not shown)---.Handle 250 and comprise grid managers 154 installations (256) and operation (258) this application.(256), customization are being installed and are carrying out in the process of (258) using, institute to computer equipment 14 changes and all is logged, so that answer the request of IPC manager 118 and when stopping (260) or unloading and using at grid managers 154, grid managers 154 can be removed this application from computer equipment 14, and removes any other change that (262) are made computer equipment 14 simultaneously when this application of installation and operation.Like this, computer equipment 14 reverts to it in the virgin state of carrying out before using, and all resources on the computer equipment 14 can be used by later application once more.This allows to need not to restart computer equipment 14, and resource just becomes available after operation is used.These changes comprise that branch is used in storage and storer (for example 32) space of operation application code and other change, for example to the distribution of communication port.

In some instances, can move a plurality of application simultaneously on the resource in single computer equipment (for example 14).According to their resource requirement, the application of grid computing environment 100 is partly classified.To use and some of computer equipment are only changed to carrying out the first time of the application of its classification required in order to move, and execution does not subsequently need these changes.In these examples, grid managers 154 only makes a change for carrying out for the first time.In addition, when unloading was used, grid managers 154 was only removed the change for the last application that is performed and stops.

Install after the application on the computer equipment in grid computing environment 100, grid managers is configured to ask and starts or stops the processing of these application. in internet price configurator (IPC) examples of applications, grid managers 154 is configured to start or stop IPC server 122.IPC manager 118 utilizations according to the resource in the current grid computing environment 100 on the computer equipment 14 after on computer equipment 14 IPC server 122 being installed, the request grid managers starts or stops the IPC server in the grid computing environment 100. after the IPC server 122 on having stopped computer equipment 14, IPC manager 118 is waited for preassigned time quantum, if indicating, the current then utilization of resources need not start IPC server 122 once more, then IPC manager 118 request grid managers 154 unloading IPC servers 122. in addition, as previously mentioned, grid managers monitor such as computer equipment 14, (for example the IPC server 120 in the operation application, 122,124 and 126) utilization of resources on the computer equipment, and utilize information to send to IPC manager 118. this

In many examples, to the application on the resource in the computer equipment handle be controlled to be operating system (OS) peculiar. grid computing environment 100 is configured to the different operating system on the process computer equipment.In addition, grid computing environment 100 is designed to (for example handle different application, internet price configurator), it needn't be redesigned in order to carry out in grid computing environment 100. and grid managers is used with universal mode control and is handled, this universal mode has reduced the interdependent property between exploitation grid managers code and the Application and Development code. provide interface to application code, so that grid managers can be found, control (for example starts, stop, suspend, continue) and check or monitor the state of handling of using. handling for the operating system that is subjected to the domination of operating system or hosted environment provides interface, and this interface comprises three aspects. an aspect of interface is a deal with data, such as handling sign, state, resource consumption is (such as CPU (central processing unit) (CPU), storer, other resource that socket binding (socket binding) or application can be used) degree, and by the application specific data of process data scheme definition.

The second aspect of interface is a bookkeeping, such as other operation that starts, stops, waiting for, continues, changes priority and defined by the bookkeeping of being supported.

The third aspect of interface is control binding and definition, such as process data scheme, the bookkeeping of being supported and communication bindings. because the application of not all operation in grid computing environment 100 can be visited this identical information and ability aspect three, therefore using to grid managers provides each to use the inquiry supported and the tabulation of order.

The interface that offers application code is that application programming interfaces (API) .API is the group of methods (being embedded in the software code) by the grid managers software dictates, utilize these methods, the programmer who writes application program (for example internet price configurator) can handle the request from grid managers.

As shown in Figure 4, IPC server 122 comprises API 302.Because API 302 is applicable to dissimilar application, so document 304 describes how grid managers 154 communicate by letter with IPC server 122 and IPC server 122 supports to pass through what request of API 302.Grid managers 154 read document 304 before starting IPC server 122.In some instances, document 304 usefulness XML are write as, and comprise Doctype description (Document Type Description, DTD) 306.DTD is follow standard generalized markup language (SGML) rule specifically defined.DTD is a kind of standard (specification), and it is followed document and identified what mark separation paragraph, what mark sign topic headings and each mark and will how to be handled.By in document 304, comprising DTD 306, grid managers 154 with DTD " reader " (or " SGML compiler ") just can be handled document 304, and can correctly translate many different types of, documents 304 of using a series of different marker codes and relevance.

Shown in Fig. 4 A, grid managers 154 uses handles 350 application of installing such as IPC server 122.Grid managers 154 reads the DTD 306 in (352) document 304, so that the mark in the identification document 304.Grid managers 154 reads the document 304 of (354) usage flag, so that identification is used for the messaging parameter of communicating by letter with IPC server 122.Grid managers 154 is set up communicating by letter of (356) and IPC server 122 according to the standard of messaging parameter.Grid managers 154 uses messaging parameters to communicate by letter (358) with IPC server 122, so as transmission such as " startup ", " stopping " and " you? " free time request.

Can on network 8, (for example carry out any application, internet price configurator) before, by asynchronous starting, and the relation of they and other grid managers is established grid managers 152,154,156,160,162 and 164 on

computer equipment

12,14,16,18,20 and 22.As shown in Figure 5, handle relation between the 400 initialization grid managers.For each grid managers (for example, grid managers 154), grid managers 154 starts on computer equipment 14 by reading (402) property file.Property file comprises the address list of the computer equipment with grid managers, and described grid managers and grid managers 154 have superior relation.This tabulation is described as first tabulation with all superior relation of other grid managers before.If (404) specified higher level's grid managers (for example grid managers 152) in this address list, then grid managers 154 requests (406) are opened to the communication channel of higher level's grid managers (for example, 152).If grid managers 152 has been activated, then grid managers 152 is by accepting to make response from the request of opening communication channel of grid managers 152. and handle 400 and comprise that grid managers 154 detects (408) and has the grid managers of inferior relation with grid managers 154 (for example grid managers 160 from being identified as, 162) if any communication channel request. handle 400 and determine that there are some requests in (410), then grid managers 154 allows to come from inferior grid managers (for example 160,162) communication channel. handle 400 and comprise that grid managers 154 checks whether (414) exist any hang-up, for request to the communication of grid managers with superior relation. if having the request of any hang-up, then grid managers 154 requests (406) are to communication channel of grid managers. and resource-query (as previously mentioned) and " heartbeat " message between the grid managers that these communication channels are used between grid managers are all being worked to guarantee each grid managers in the grid computing environment 100.

In case have the grid managers 152 of the relation of having set up, 154,156,160,162 and 164 operations, grid managers just is used to the proper handling of grid computing environment 100. and the function of grid managers usually is enhanced in the life cycle of grid computing environment 100. and it is impossible or inconvenient often to close grid computing environment 100 and start the grid computing environment 100 with enhancement function. configuration grid managers 152,154,156,160,162 and 164 so that only can cause minimum influence when changing to the user of grid computing environment 100. in order to realize this transparency, for user interface provides API, so that the keeper of grid computing environment 100 can be individually or is all visited each grid managers 152 together, 154,156,160,162 and 164. these API are static, reason is that it only comprises a kind of method, promptly, the character string .API that comprises the order of being keyed in by the keeper is dynamic, and reason is that this character string can comprise many different orders.

In some cases, grid managers is to use the exploitation of Java programming language. in these situations, can be distributed to the newer command of grid managers by dynamically load java class support new or that revise via Classloader (classloader). need not to close grid managers in the grid computing environment 100 and just can realize this dynamic access code. use java class loader, during the example of the class of each generating mesh manager, the definition of class and behavior can both be updated, thereby provide new function to grid computing environment 100.

The another kind of mode that need not to close grid computing environment 100 and dynamically revise the function of grid computing environment 100 is to change hierarchical relationship between the grid managers, remove grid managers or add new grid managers. the API that provides for the management of grid computing environment 100 also is configured to send to each grid managers and has the character string of order to delete existing relation or to add new relation.
