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

The method is widely applicable to application occasions with multi-thread parallel processing requirements, software developers are guided to perform multi-thread parallel optimization improvement on prior software rapidly and efficiently with short developing periods and low developing costs, the utilization of system resources by software is optimized, data reading and computing and mutual masking of write-back data are achieved, the software running time is shortened furthest, the hardware resource utilization rate is improved apparently, and the software computing efficiency and the software whole performance are enhanced.

Description

technical field [0001] The invention relates to the field of computer high-performance computing, in particular to a software performance optimization method based on a CPU multi-core platform. 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. With the popularization of processors with multi-core architecture, multi-entry / thread parallel processing of application software will gradually become the mainstream. [0003] The ultimate goal of hardware development is to promote the performance of application software and thus the performance of the entire computing system. 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 exist...
