Abstract

The invention discloses a process migration method, a computing device and a readable storage medium. The method includes: when a first process wakes up a second process, determining whether the CPU where the first process is located is in an idle state, and the first process is to execute the wake-up The process of the process, the second process is the process awakened by the first process; if the CPU where the first process is located is not in an idle state, the second process is migrated to the second process based on the affinity between the first process and the second process. in the target CPU of the computing device. The program running performance is improved by the process migration method of the present invention.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a process migration method, a computing device and a readable storage medium. Background technique [0002] When two processes share variables, share memory, share instruction segments, and frequently compete for the same lock, then the two processes have process affinity. Shared content is its common resource. For processes whose shared resources are memory or variables or instruction segments, if they run on the same CPU, they can share the CPU's private cache and only need to load them once. If running on a different CPU, the cache needs to be loaded one more time. And after one CPU modifies the shared variable or memory, the other CPU needs to synchronize the cache state through the bus, and the cost is relatively large. [0003] In the existing process migration method, the kernel will preferentially select the CPU with less load, and migrate the wakee proc...
