Specific embodiment
Below in conjunction with attached drawing, an exemplary embodiment of the present invention will be described, including the various of the embodiment of the present invention
Details should think them only exemplary to help understanding.Therefore, those of ordinary skill in the art should recognize
It arrives, it can be with various changes and modifications are made to the embodiments described herein, without departing from scope and spirit of the present invention.Together
Sample, for clarity and conciseness, descriptions of well-known functions and structures are omitted from the following description.
It should be noted that the embodiment of the present invention is applicable in task allocation scenarios, for example, TBSchedule,
Clover。
Distributed system error-prone, especially processing competition with it is synchronous during, existing solution, usually
Distributed system is coordinated based on reliable coordination system, for example, Zookeeper, and function provided by Zookeeper is extremely
It less include: configuring maintenance, name Service, distributed synchronization, group service etc..
More mature universal in view of zookeeper, present invention is primarily based on zookeeper implementations, and do not do to Zookeeper
Any improvement has only used some functions of Zookeeper.But it should be recognized that it is identical that its function also can be used
Distributed component.
It lays down a definition below to noun according to the present invention:
Proof of work (Proof-of-Work, PoW) is that a kind of corresponding with service is abused with resource or service is blocked to attack
The economic measure hit.User is usually required to carry out some time-consuming complex calculations appropriate, and answer can be quick by service side
Checking computations, time, equipment and the energy consumed using this to ensure to service with resource are made by real demand as Cost of Guarantee
With.
Used time MS: task performer amount of calculation proves the time used, is counted with millisecond.
Actuator: specific execution task applies role, is made of hardware machine and software systems.In the present invention, it holds
Row device is divided into the Master host node actuator of distribution task and handles the task performer of task.
Master host node machine: carrying out job enquiry and that distributes applies role, can merge with actuator code
It splits, is made of hardware machine and software systems.
Node (Master node or Executor node): Zookeeper term can be used for storing for distributed system
The unit of data.Node can be named as Master or Executor, under node can deposit data or newly-built child node, it is generally tree-like
Structure.
Referring to Fig. 1, thus it is shown that a kind of broad flow diagram of the method for task schedule provided in an embodiment of the present invention, including
Following steps:
S101: determining task performer, sends workload computing and instructs to each task performer.
S102: receiving the end value that each task performer is fed back, and determines each task performer feedback result value institute
The time needed, to calculate the working efficiency of each task performer；Wherein, end value is corresponding to workload computing instruction.
S103: determining task amount to be processed, according to the working efficiency of each task performer, carries out task amount distribution.
The present invention is mainly made of two roles: host node Master and actuator Executor, the two roles pass through
It carries out Master election in Zookeeper to determine, to guarantee to only exist a host node in synchronization system.To make system
Sound and stable operation, the present invention are illustrated with there is effective Master host node always.
To avoid subsequent title from obscuring, later for Master host node actuator, abbreviation Master host node；For
The actuator that task is handled under Executor node, abbreviation task performer.
For step S101, election for host node can be in system starting, be also possible to each child node
Detecting that host node is deposited when abnormal, registration request can be the identification information of each actuator, for example, the IP of actuator
Location.Specifically:
1) when system starts for the first time, host node can be elected, Zookeeper can receive the main section of each actuator at this time
Point registration request determines that the actuator that election is succeeded in registration first is main node M aster, remaining election master node failure is held
Row device goes under Executor node to be registered as child node again, so that Master distributes task accordingly；
2) after system starts and elects host node, Zookeeper can be based on predetermined detection period, periodic detection
Whether Master node machine survives, if existing state is abnormal (for example, delay machine, network failure), sends to all actuators
Notice (including this abnormal Master node machine), to re-elect host node Master.
Extremely is resulted in the need for for host node, the host node redefined continues in undertaking the case where re-registering host node
The work of one host node, and its unfinished task amount, can distribute to other task performers and be executed.
In addition, Master host node does not need processing task, therefore for the registration request of host node, wherein without comprising
Workload value, but the IP address for having actuator is included at least, appoint convenient for subsequent Master host node to the distribution of actuator child node
It is used when business.
Registration for task performer machine, registration content are the IP address and its initialization amount PoW of actuator.
And since the child node of Executor is registrable multiple, communicate in normal situation, a possibility that registration failure is lower, if but losing
It loses, then the actuator will not be assigned task.In addition, if can periodically be retransmitted when the actuator detects unregistered success
Registration request reduces the wasting of resources.
Referring specifically to shown in Fig. 2, system is coordinated for zookeeper, TASK_TYPE_1 is task type node, the section
There are Master host node and Executor node under point.A node, content Master can wherein be increased under Master node newly
The IP address of machine；Registrable multiple nodes under Executor node, content are the IP address and PoW value of Executor machine.
IP address information is saved in Master node, is elected as Master to distinguish the actuator of which IP address.Its
The task performer of minor node can inquire Master host node content, periodically to distinguish one's own duty and to re-elect.
Wherein, this re-elect can be detect Master host node exception after notified by Master, be also possible to by actuator
Laggard rob of querying node Master host node disappearance accounts for.
After determining Master host node, by the actuator being registered under Master host node, it is registered in by reading
The identification information of task performer under Executor node obtains task performer list.Master host node is based on IP
Location is communicated with each task performer in actuator list, and notice carries out proof of work calculating or task processing.
Further, for task performer list generated, since the quantity of task performer may increase at any time
Or it reduces.To guarantee follow-up work processing effectively, need to detect currently valid task performer quantity, to guarantee that task can
Correct distribution.
Master host node is sent to the workload computing instruction of each task performer, can be and is sent out with content-form
It send, such as " calculating its hash value top N after increasing variable by random number is 0 ", is a kind of proof of work algorithm, wherein N
Can be by actuator child node quantity self-setting, and any data hash value is all different and completely random, such as:
1) after " 0 " is calculated by MD5 (Message Digest Algorithm MD5, Message Digest 5), hash value
For " CFCD208495D565EF66E7DFF9F98764DA "；
2) to find the hash value that first 1 is 0, then 27 hash value is obtained after being added to 27 since 0
"02E74F10E0327AD868D138F2B4FDD6F0"；
3) to find the hash value that first 2 are 0, then 168 is added to and obtains its hash value
“006F52E9102A8D3BE2FE5614F42BA989”。
For step S102, each task performer starts to calculate after receiving workload computing instruction, and will calculate
End value returns to Master host node.Here end value, be meet the end value of proof of work algorithm requirement, such as
Hash value is " 3636638817772E42B59D74CFF571FBB3 ".
But it should be recognized that task performer, proves algorithm, institute for the different operating amount that Master host node issues
The end value of return is different, but all meets proof of work algorithm requirement.Such as above-mentioned example, if it is desired to the Hash since 0
It is worth the number of front two, task performer then returns to 168 and waits numerical value.
It further, is raising task treatment effeciency, before the working efficiency of calculating task actuator, the main section of Master
Point can dynamically be detected, for the end value and institute's elapsed time that each task performer is returned to hold to task
Row device is screened, specifically:
1) whether correct the end value that each task performer is returned is verified: for example, it is desirable that the front two of hash value is
0, return value is 168 and is verified；But if return value is 169, the hash value that host node calculates 169 is
" 3636638817772E42B59D74CFF571FBB3 " is undesirable, then does not pass through verifying；
2) it verifies each task performer and returns the result the time consumed by value: for example, due to degraded performance, network event
The reasons such as delay machine, cause certain time not calculate end value in barrier, calculating process, these can not returned the result to appointing for value
Business actuator weeds out.
The time that Master host node is returned according to each task performer calculates the work effect of each task performer
Rate rate is referred to as being allocation proportion.For example, 752ms --- first actuator used time when 10 actuators share
10ms, second used time 23ms ... ..., the last one used time 10ms, by determining time reciprocal value and each time reciprocal value
The sum of ratio, for task performer 1, working efficiency rate are as follows:
Rate1=(1/10)/[(1/10)+(1/23)+...+(1/10)].
It, can be according to each task when Master host node is inquired or receives task to be treated for step S103
The working efficiency of actuator and just in untreated task amount, is intelligently allocated:
1) for system initial start up phase, the proof of work of each task performer is 0, at this time can direct root
According to its working efficiency, the task amount accordingly distributed is determined；That is working efficiency * general assignment amount；
2) is had been turned on for system the stage, when receiving new task, there may be partial task actuator, there are also not complete
At task, need task quantity in combination processing to carry out task distribution at this time, such as execute task in each task performer
After 10s, start the distribution of the second subtask, is still the i.e. rate=(task amount in processing+newly distribute task based on working efficiency
Amount)/general assignment amount, therefore newly distribute task amount in task amount=general assignment amount * rate- processing.
Further, some numerical results value may not be integer, can be using the side for rounding up or being rounded downwards
Formula determines task sendout.Distribution for remaining task amount (general assignment amount-distributed task amount), can there are many real
Apply mode:
1) according to the mode to round up, remaining task amount can be distributed to the task execution minimum to working efficiency
Device, to improve overall task treatment effeciency；
2) according to the mode being rounded downwards, remaining task amount can be distributed to the highest task execution of working efficiency
Overall task treatment effeciency equally can be improved in device；
3) performance for being not necessarily based on each machine is ranked up, and directly carries out order-assigned according to task performer list, will
Remaining task amount distributes into table the last one task performer,.
Method provided by above-described embodiment provides a kind of task process performance based on machine and smart allocation task
Thinking realized " able people should do more work " with giving full play to the processing capacity of high performance tasks actuator, and then improve at overall task
Manage speed.
Referring to Fig. 3, a kind of method flow schematic diagram of optional task schedule according to an embodiment of the present invention is shown, is wrapped
Include following steps:
S301: determining task performer, sends workload computing and instructs to each task performer.
S302: receiving the end value that each task performer is fed back, and determines each task performer feedback result value institute
The time needed, the total time of all task performer feedback result values is counted, the proof of work of each task performer is calculated
Value；Wherein, proof of work value=all task performers total time/individual task actuator time.
S303: according to the proof of work value of each task performer, the amount of work card of all task performers is determined
Bright value calculates the working efficiency of each task performer；Wherein, working efficiency=individual task actuator proof of work
Value/all task performers amount of work proof value.
S304: determining task amount to be processed, according to the working efficiency of each task performer, carries out task amount distribution.
In above embodiment, step S301, S304 can distinguish the description of step S101, S103 shown in Figure 1, herein
It repeats no more.
In above embodiment, for step S302, Master host node according to each task performer returned when
Between, the PoW value of each task performer is calculated, for example, 752ms when 10 actuators share, with 752ms divided by each actuator
The time of cost obtains the PoW value of each task performer, it may be assumed that
Wherein, MSNIndicate the used time of task performer N, M is the quantity of effective task performer, PoWNAppoint to calculate gained
The proof of work value of business actuator N.
Further, its PoW value can be safeguarded and (be updated and save) to the time returned for each task performer,
For example, its PoW value is 75.20 after task performer 1 calculates for the first time, then host node needs to save this value, and in this, as
Distribute the foundation of task amount；After second obtains proof of work, PoW value is 5.94, then host node machine needs
5.94 are revised as by 75.20.
Further, proof of work value can be updated according to predetermined period, for example, 10 minutes, 5 minutes,
It can be other times voluntarily configured.For example, the PoW value of first time calculating task actuator 1 be 75.20, but 10 minutes it
Afterwards, its availability is caused to decline since network jitter or other work occupy CPU, its PoW value obtained by second of calculating is
5.94, then the task quantity of lower sub-distribution will be reduced.
For step S303, it is based on gained proof of work value, can determine corresponding working efficiency, it may be assumed that
Wherein, rateNFor the working efficiency of task performer N, ∑ PoW is the cumulative of all task performer PoW values.
Equally, in machine use process, it is understood that there may be machine loss, using the situations such as abnormal causes its working efficiency to drop
It is low.Resulting working efficiency is calculated every time as a result, to be also not quite similar.It, can also be with dimension for the working efficiency being calculated
The mode of shield carries out preservation update, is convenient for subsequent query, improves task and distributes accuracy.
For each task performer, resulting PoW value and corresponding working efficiency can be generated table, be stored in
It is as shown in table 1 below in node:
1 PoW and rate value example of table
It should be noted that since the quantity of task performer may change at any time, and workload computing instruction is not
It can be sent as its quantity changes every time and (avoid server stress excessive), for example, effective task performer number before 10s
Amount is 10, and quantity becomes 20 after 10s, but workload computing instruction is 10min primary.
Task performer quantity is changed, and the case where the proof of work update cycle is not up to, it can be with direct basis
The proof of work value of each task performer, calculates corresponding working efficiency, without relying on the used time, and is convenient for follow-up management,
Reduce server service pressure.
Method provided by above-described embodiment specifically calculates each task performer according to the mode of proof of work
Working efficiency.For task performer quantity change and not up to the proof of work update cycle the case where, can be with direct basis
The proof of work value of each task performer, determines corresponding working efficiency.
Referring to fig. 4, a kind of method flow schematic diagram of optional task schedule according to an embodiment of the present invention is shown, is wrapped
Include following steps:
S401: determining task performer, sends workload computing and instructs to each task performer.
S402: receiving the end value that each task performer is fed back, and determines each task performer feedback result value institute
The time needed, to calculate the working efficiency of each task performer；Wherein, end value is corresponding to workload computing instruction.
S403: receiving newly assigned task amount, obtains each task performer currently untreated task amount, obtains wait locate
The task amount of reason.
S404: according to task amount to be processed, the working efficiency of each task performer and current untreated task
