Problems solved by technology

However, with the diversification of computing device architecture and multi-core, the way that software systems only rely on hardware updates to improve performance is no longer in line with the development trend of existing hardware. For example, traditional single-threaded serial programs run on multi-core computing devices. Can not show better performance

Abstract

The invention provides a multi-thread parallel processing method based on a multi-thread programming and a message queue, belonging to the field of high-performance computation of a computer. The parallelization of traditional single-thread serial software is modified, and current modern multi-core CPU (Central Processing Unit) computation equipment, a pthread multi-thread parallel computing technology and a technology for realizing in-thread communication of the message queue are utilized. The method comprises the following steps of: in a single node, establishing three types of pthread threads including a reading thread, a computing thread and a writing thread, wherein the quantity of each type of the threads is flexible and configurable; exploring multi-buffering and establishing four queues for the in-thread communication; and allocating a computing task and managing a buffering space resource. The method is widely applied to the application field with multi-thread parallel processing requirements; a software developer is guided to carry out multi-thread modification on existing software so as to realize the optimization of the utilization of a system resource; and the hardware resource utilization rate is obviously improved, and the computation efficiency of software and the whole performance of the software are improved.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a multi-thread parallel processing method based on multi-thread programming and message queues. Background technique [0002] Driven by new technologies, hardware systems are undergoing rapid evolution, showing better performance and lower prices, such as the development of traditional CPUs from single-core to multi-core to many-core. However, with the diversification of computing device architecture and multi-core, the way that software systems only rely on hardware updates to improve performance is no longer in line with the development trend of existing hardware. For example, traditional single-threaded serial programs run on multi-core computing devices. Couldn't show better performance. The ultimate goal of hardware development is to promote the performance of application software and thus the performance of the entire computing system. Therefore, the softwar...
