基于龙芯3A2000处理器的高性能Goto BLAS库的实现
Implementation of a high-performance Goto BLAS based on Loongson 3A2000 processor
摘要
Abstract
Linpack was applied to evaluation of the performance of a computer system,and the Goto BLAS library was used as the function operation library.The performance of the library has a large impact on Linpack test results.To achieve its high performance,the study observed the performance expression of the Goto BLAS library on the Loongson 3 A2000 processor,and analyzed the testing software's execution flow and data processing methods,and then,according to the structural features of the processor,reasonably allocated the block matrix and optimized the scheme for implementation of the core loop in the function.Meanwhile,the data-fetching technologies of software and hardware,and the optimized TLB configuration schemes were adopted.With the combined effects of these optimizations,the efficiency of float point component on the simulation platform reached more than 90％,which means the optimization schemes achieved the significant results in this experiment.关键词
