Embodiment Construction

[0074] In order to solve the defect that the static delay scheduling method used in the prior art makes the job submitted by the user usually unable to be executed within the predetermined time limit, resulting in low execution efficiency of the overall job, the main innovations of the present invention are:

[0075] 1) In the server cluster 200, designate a main server 201 specially used for job acceptance and job assignment. After the main server 201 receives the task processing request initiated by the sub-server M for the jth job in the job queue to be processed, And when the sub-server M is not the local server of the jth job, based on the resource estimation model, the number of task processing requests E from the jth job that can be obtained from its local server in a data block transmission cycle T j Carry out quantitative calculations, and process the number of requests E according to the calculated tasks j Reasonably allocate the processing tasks of the jth job;

Abstract

The invention discloses a job scheduling method and a job scheduling system. The job scheduling system includes a job submitting device and a server cluster composed of a main server and multiple sub-servers. The main server is used to receive a task processing request submitted by any sub-server M in the server cluster for the jth job in the queue to be processed and determine that the sub-server M is not the local server of the j-th job, based on resources The prediction model quantifies and calculates the number of task processing requests Ej initiated by the local server of the j-th job in the server cluster to the j-th job within a data block transmission period T. The main server is also used to assign the processing task of the jth job to the sub-server M when judging that the number of times Ej of the task processing requests is less than once, or to execute the jth job when the number of times Ej of the task processing requests reaches or exceeds one time. Delayed scheduling of jobs. The invention can greatly improve the scheduling efficiency of the overall operation.

Description

technical field [0001] The present invention relates to the technical field of task allocation, and more specifically, to a job scheduling method and a job scheduling system. Background technique [0002] In order to improve the acquisition level of local data resources of jobs and shorten the execution time of a single job, the static delay scheduling method has been widely used. However, the static delay scheduling method also has the following defects: [0003] 1) In order to ensure that the job submitted by the user can obtain local data resources and improve the execution efficiency of a single job, when the job does not obtain the processing request from the local data resource, it is necessary to perform delayed scheduling of the job, which makes it difficult for the job to Completed within the scheduled time. [0004] 2) The static delay scheduling method reduces the execution efficiency of the overall job while improving the execution efficiency of a single job. ...
