Abstract

The invention relates to an algorithm parallel processing method and system based on a heterogeneous many-core processor, and the method comprises the steps: taking a code segment with large operationtime consumption in a serial program as a parallel computing object, carrying out the task division according to the characteristics, determining the task division of a master core and a slave core array, handing over the time-consuming computing to the slave core array for execution, by each slave core, actively acquiring a task and data used for calculation from the main memory and returns a calculation result to the main core, by the main core, updating the main memory data in an asynchronous serial mode so as to avoid data read-write errors caused by data dependence, meanwhile, for the problem of time consumption of master-slave core communication, packaging a single data item in a structural body to realize data packaging, and setting a data master memory address 256B pair boundary of a master core to realize that the single data copy granularity is not less than 256B, so that the bandwidth of a single core group is utilized to the maximum extent, and the data transmission performance is optimized, consumption hiding of communication time is realized by using a double-buffer mechanism, and the parallel efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of parallel computing, and more specifically, to a method and system for parallel algorithm processing based on heterogeneous many-core processors. Background technique [0002] In the field of high-performance processors, limited by the three major factors of power consumption, interconnection, and complexity, the growth rate of processor computing performance can no longer meet Moore's Law, and heterogeneous parallel acceleration methods have become a new direction of thinking. Coupled with the continuous progress of on-chip microstructure and low power consumption technology, heterogeneous many-core processors have gradually become the development trend of processor design. Therefore, using heterogeneous many-core processors to accelerate algorithm execution efficiency has also become an important research field. [0003] The Sunway TaihuLight supercomputer, which is completely independently deve...
