A scheduling execution method, device and medium based on multi-thread tasks

Abstract

The embodiment of the present invention discloses a scheduling execution method, device and medium based on multi-threaded tasks, which sequentially buffer the built timer events into the task queue according to the time sequence of task execution; update the global time counter by using preset working threads , and use the current time recorded by the global time counter as the initial time of all local time counters. When the current time recorded by the local time counter of the first timer event reaches the task execution time corresponding to the first timer event, the corresponding worker thread is used to execute the pending task corresponding to the first timer event; The current time recorded by the local time counter of the first timer event is used as the initial time of the next timer event, until all timer events in the task queue are polled, the operation ends. On the premise of not increasing the cost, the problem of clock synchronization in the process of multi-thread task scheduling and execution is solved.

Description

technical field [0001] The present invention relates to the technical field of storage systems, and in particular to a scheduling execution method, device and computer-readable storage medium based on multi-thread tasks. Background technique [0002] As the storage system has to process more and more IO requests (that is, tasks to be performed), the performance requirements of the storage system are also higher and higher. In the case of more and more tasks to be performed, in order to improve the performance of task processing, at present, a common method is to create as many threads as possible to increase the degree of concurrency. Under the application background of multi-thread task scheduling and execution, the selection and design of timer processing mode is particularly critical. [0003] In the existing computer multi-node system, two ideas of hardware and software are generally used to realize the timer function. The hardware method can include satellite signal t...
