Thread number adjusting method and device, equipment and computer storage medium

Abstract

The embodiment of the invention provides a thread number adjusting method and device, equipment and a computer storage medium. The method comprises: obtaining multiple first tasks and resources needed for executing the multiple first tasks; obtaining first mapping information according to the plurality of first tasks and resources required for executing the plurality of first tasks; determining first information according to the first mapping information and a preset decision model; determining an alternative adjustment action corresponding to the first information meeting a preset threshold value as a target adjustment action; and adjusting the number of the first mapping relationships according to the target adjustment action. According to the invention, the number of threads for executing tasks can be flexibly adjusted, and the task execution efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of business support, in particular to a method, device, equipment and computer storage medium for adjusting the number of threads. Background technique [0002] In the traditional process of executing tasks, the system executes tasks and allocates resources by creating threads, each thread executes different tasks in parallel, and the number of threads (or concurrency) for executing tasks is usually manually configured based on experience, and in the entire During task execution, the number of threads is fixed. In a working system, tasks and resources are always in the relationship of demand and demand, and the execution of each task requires a certain amount of resources. [0003] In actual situations, among all the resources required by the system, the resource (or bottleneck resource) with the least supply and the largest demand changes with time, and the existing technology uses a fixed number o...

Problems solved by technology

[0003] In actual situations, among all the resources required by the system, the resource (or bottleneck resource) with the least supply and the largest demand changes with time, and the existing technology uses a fixed number of threads to perform tasks, which cannot solve the above bottlenecks. Flexible response to time-varying resources

For example, when the system is faced with a large number of tasks, under normal circumstances all threads should be executing tasks, and some tasks are waiting due to the small number of threads. In the ready state, tasks cannot be executed. As a result, some tasks are waiting to release threads, while some threads are waiting to release bottleneck resources, resulting in a decrease in the task execution efficiency of the system.
