Problems solved by technology

At present, when the task decomposition mode is adopted, when the priority and processing speed of subtasks change, manual intervention is required to adjust the program to adapt to this change, and the computer software system cannot be automatically configured to cope with this change Occurrence, thus causing limitations to the application of parallel task decomposition mode, so that the parallel task processing ability of the computer is reduced

Embodiment Construction

[0031] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0032] see figure 1 Shown is a flow chart of the method for implementing task decomposition and parallel processing control in the computer software system of the present invention.

[0033] In one embodiment, the computer software system has a task scheduling unit connected between the task receiving end and the processing unit, and the method includes the following steps:

[0034] (1) The task scheduling unit receives a task from the task receiving end;

[0035] (2) The task scheduling unit splits a task into a plurality of independently executable subtasks;

[0036] (3) The task scheduling unit determines the dependencies between the subtasks;

[0037] (4) The task scheduling unit stores the dependencies between the subtasks as matrix structure data;

[0038] (5) The task scheduling unit determines subtask sequences that can be execute...

Abstract

The invention relates to a method for implementing task decomposition and parallel processing in a computer software system. The computer software system is provided with a task scheduling unit connected between a task receiving end and a processing unit. The method includes that the task scheduling unit decomposes a task into subtasks, stores dependent relations among the subtasks as matrix structure data, and confirms sequence of the subtasks which can be processed parallelly according to the matrix structure data, and a processor is used for parallel processing. Using the method can respond to various changes in a configuration manner, corresponding adjustments can be performed dynamically to automatically implement task decomposition, manual interference is not needed, parallel task decomposition efficiency is improved, and parallel task processing capacity of a computer is improved greatly. In addition, the method for implementing task decomposition and parallel processing in the computer software system is simple and convenient in application way, low in implementation cost and wider in application range.

Description

technical field [0001] The present invention relates to the technical field of computer software systems, in particular to the technical field of task processing methods in computer software systems, and specifically refers to a method for realizing task decomposition and parallel processing control in computer software systems. Background technique [0002] In a computer system with only one single-core CPU, all tasks are processed serially, which is slower and less efficient. As computer systems with dual-core or multi-core CPUs or with multiple CPUs are widely used, parallel processing task processing methods are also increasingly used in computer software systems. [0003] Parallel processing means that the computer completes two or more tasks of the same or different nature at the same time or within the same time interval. The most significant advantage of parallel processing is that it increases the computing speed. Comparing the n-bit serial operation with the n-bi...
