议题一: Kunpeng GCC特性详解---- FTZ (谢志恒)
1. 在 X86/ICC/Linux 开发环境中,用户或者应用时常会使用-ftz(flush-to-zero)选项,将一些极小数当作 0 处理,可以提升浮点数值计算运算的效率。在 ARM/GCC/Linux 开发环境中,GCC 并未提供单独的选项使能或关闭FTZ功能,因此在 Kunpeng GCC 编译器中引入-fftz选项来单独控制FTZ功能
2. 介绍Kunpeng GCC FTZ功能实现,以及-fftz选项实现。
3. 展示Kunpeng GCC FTZ测试结果
4. 针对会上讨论的ftz在ARM和X86上表现不一致的问题,会后已与ARM同事讨论,结论为一般硬件实现FTZ功能与IEEE754标准不同[1][2],如果用户希望兼容IEEE754,则建议关闭FTZ。
该特性在用户关注计算性能的时候开启,如高性能计算的场景,详细信息请参考附件PPT.
