基于FT2000处理器内存性能测试及优化

FT2000 processor-based Memory Performance Testing and Optimization

STREAM作为微处理器上广泛应用于测试各种计算机的内存性能的基准测试程序,如何使得其在FT2000/4处理器上发挥高性能是具有挑战性的研究工作。对STREAM工具的各参数进行测试并且合理的设置参数数值可以使得程序性能大幅度提高。数据测试结果表明,优化后,并行程序的最高访存性能能达到13.93GB/s,对比优化前的最高访存性能提高了56.34%。

STREAM is a benchmark program widely used to test memory performance of various computers on microprocessors,and it is challenging to make it perform well on FT2000/4 processors.Testing of the parameters of the STREAM tool and reasonable setting of the parameter values can lead to significant improvements in program performance.The data test results show that after optimization,the maximum access performance of the parallel program can reach 13.93GB/s,which is 56.34%higher than the maximum access performance before optimization.
