Problems solved by technology

However, the creation and destruction of threads requires a cost. The time to create a new thread probably takes several hundred milliseconds of the system, and it also consumes other resources such as memory. In short, it is unfavorable to repeatedly create and destroy threads.

Abstract

The invention relates to a method and a system for scheduling multitasking thread pools, which create task threads according to the number of real central processing units (CPUs) of a computer, set up the thread pools according to priority of the task threads, choose threads in the thread pools corresponding to priority according to the priority of the task threads to be executed, finally relate task algorithm to the threads and start thread scheduling algorithm to execute the tasks. By adopting the method and the system for scheduling multitasking thread pools, users can create the thread pools according to the priority of the task threads and classify and manage the threads. Due to a thread creating and recovering device of threads arranged in the method and the system, utilization ratio of the threads is improved, and resource waste is avoided.

Description

technical field [0001] The invention belongs to the technical field of video processing, and in particular relates to a multi-task thread pool scheduling method and system. Background technique [0002] In the post-processing of images / videos, due to the complexity of algorithms, the efficiency of program production will be low. However, with the continuous improvement of the computer level, computers with multi-core CPUs are becoming more and more popular, which provides hardware support for improving the real-time performance of the system during post-processing of images / videos. In order to make full use of existing hardware resources, a feasible way is to start as many threads as possible to let the CPUs work, but the actual situation is not that the more CPUs started, the better. When the number of threads reaches a certain value, as With the addition of new threads, the response time of the system to a single task is getting longer and slower, and if it continues to i...
