Problems solved by technology

[0004] But there are problems: 1) For multi-core CPUs, because the above method starts a large number of threads, the CPU will switch between threads frequently, and the program itself will cause excessive CPU occupation, resulting in unstable CPU usage; 2) It is necessary to control the CPU utilization rate by starting and destroying threads. Since many threads start and destroy a certain amount of time, the real-time performance of CPU adjustment will be poor and the lag will be serious; 3) static errors in the system cannot be eliminated, and the The CPU usage has a certain error from the expected value, and this error is closely related to the specific environment and cannot be predicted.

Abstract

The invention discloses a method for controlling CPU utilization rate. The method comprises: starting a work process, wherein the work process and a target CPU have binding relation; obtaining current utilization rate and target utilization rate of the target CPU, and obtaining an error value between the current utilization rate and the target utilization rate; according to the error value, generating work time of the work process; and according to the work time of the work process, controlling the work process. The method can make CPU utilization rate control achieve characteristics of stable effect, high real-time property, and high accuracy. The invention also discloses a device for controlling CPU utilization rate.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for controlling CPU utilization. Background technique [0002] At present, in many high-reliability software tests, a very important test scenario is the performance test of the software under high pressure. And this high stress often manifests itself in high CPU usage. As another example, in many high-reliability systems, strong disaster handling plans and disaster recovery protection mechanisms are required to support them, and most disaster recovery protection mechanisms rely on a monitoring device that can monitor system status in real time, such as CPU usage, memory usage, etc. Since when a certain system state reaches a precise set value, the disaster recovery protection mechanism will be triggered to automatically implement a certain processing plan. Therefore, during the test process of this disaster recovery mechanism, the real-time cont...
