摘　　要：主要对STREAM内存性能测试工具进行了深入研究,同时对内存性能影响因素进行了分析,详细地阐述了CPU、内存、编译器等影响因素对内存性能可能存在的影响点,进一步选取不同架构CPU、不同内存速率、不同版本的GCC编译器设计相关案例进行内存性能测试。测试结果表明,CPU架构、内存速率与GCC编译器版本均对内存性能有一定影响,其中CPU架构影响最大,满线程测试结果最大相差4.17倍,内存速率影响最小,单线程测试结果几乎无影响。The STREAM memory performance test tool is studied in depth,and the influencing factors of memory performance are analyzed.The possible impact points of CPU,memory and compiler on memory performance are described in detail,and CPUs of different architecture,different memory rates,different versions of GCC compiler are further selected to design related cases for memory performance testing.The test results show that CPU architecture,memory rate and GCC compiler version all have some influence on memory performance,and the CPU architecture has the most influence,and the maximum difference of full thread test results is 4.17 times,the memory rate effect is minimal,and single-threaded test results have little effect.
