Problems solved by technology

But if it is a 64-way server, that is, 64 CPUs are integrated, and all the CPUs are not on the same processor integrated board. When one of the CPUs of the server is busy, the task will be migrated to other CPUs. The CPU may be the same processor integrated board as the task, or it may be migrated to other processor integrated boards, which is also called cross-processor integrated boards, and ping-pong type processor integrated board switching may occur. would result in a severe loss of performance

Abstract

The invention discloses a scheduling method of task running. The method comprises the steps that when CPU overloads in a task running process, corresponding processing unit integrated board information of a task is obtained, wherein the processing unit integrated board information is obtained when the task is established; task loads of all CPU on the corresponding processing unit integrated boardare obtained according to the processing unit integrated board information; CPU selective processing is conducted on all CPU according to all task loads based on preset rules to obtain target CPU; thetask is scheduled to the target CPU. By means of the method, performance loss due to the occurrence of scheduling crossing the processing uni integrated board when the migration of the task is conducted is prevented, the delay of task scheduling is reduced, and the performance when scheduling running is conducted is improved. The invention further discloses a scheduling device and server for taskrunning and a computer readable storage medium which have the above advantages.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a task execution scheduling method, a scheduling device, a server, and a computer-readable storage medium. Background technique [0002] With the continuous development of computer technology, the integration of CPU (Central Processing Unit) is getting higher and higher, and multiple CPUs can be integrated in one server, for example, when 64 CPUs are integrated in one server, a 64 road server. Although the number of CPUs that the operating system can support is currently unlimited, at that time, the multi-CPU scheduling did not take into account the slowdown of system access due to the physical connection between CPUs. [0003] Specifically, in the current 8-way server integrated with 8 CPUs, switching tasks among 8 CPUs will not cause loss of task access performance. But if it is a 64-way server, that is, 64 CPUs are integrated, and all the CPUs are not on the ...
