摘要

深入分析了飞腾处理器FT-1500A与商用处理器Intel XEON在性能上的差异。在微基准测试层面,评测了两个平台能够达到的最大可获得性能(浮点性能、访存延迟和访存带宽)。在应用层面,选取一个典型的海洋预报数值模拟软件,研究了如何将一个开源代码移植到飞腾处理器和商用处理器上,探讨了该软件在两个平台上的单核性能与多核性能,分析了性能差异的原因并提出了相应的优化建议。认为FT-1500A已经有良好的生态基础(操作系统、编译器和工具链),使得移植典型科学计算程序简单可行,虽然跟商用平台相比,飞腾处理器在性能上存在着差距,但考虑到其在功耗上的优势,飞腾处理器将是一个非常具有应用前景的平台。
        We give an in-depth performance comparison between FT-1500 Aand Intel XEON processors.At the micro benchmarking level,we measure the maximum performance(FLOPS,memory access latency,and bandwidth)that the two platforms can achieve.At application level,we select a typical ocean forecasting numerical simulation software,and study how to port an open source code to FT-1500 A processor and commercial Intel XEON processor,discuss the single-core performance and the multi-core performance of the software on the two platforms,analyze the reasons for performance difference,and propose corresponding optimization suggestions.Overall,we conclude that the FT-1500 Aprocessor already has a good ecosystem basis including operating system,compiler and the related tools,which facilitates the porting process of classical scientific programs.Although there is a noticeable performance slowdown compared to the commercial Intel XEON processor,we argue that FT-1500 Aprocessor is still a promising candidate for future applications especially when power consumption is taken into account.
