至强皮骑士与海湾合作委员会的内在角色 [英] Xeon Phi Knights Corner intrinsics with GCC

问题描述

我正在考虑购买至尊披肩骑士角（KNC）协处理器卡。但我没有英特尔编译器，我也没有兴趣购买一个（而非商业版似乎不再是一种选择）。

它出现GCC正在获得对至强Phi的OpenMP支持。 是否有某个版本的GCC或支持 KNC内部函数 >

解决方案

您必须使用内联程序集而不是内部函数来使用MIC矢量指令和GCC。

英特尔非商业软件程序最近重新启动。请参阅 https://software.intel.com/en-us/qualify-免费软件了解详情。

I'm thinking of purchasing a Xeon Phi Knights Corner (KNC) coprocessor card. But I don't own an Intel Compiler and I have no interest in purchasing one (and the non-commercial version no longer seems to be an option).

It appears that GCC is getting OpenMP support for the Xeon Phi. Is there some version of GCC or an extension to GCC that supports the KNC intrinsics?

Note that the 512-bit SIMD of the KNC is not compatible withe AVX512 (though the next version Knights Landing will be).

解决方案

You will have to use inline assembly rather than intrinsics to use the MIC vector instructions with GCC.

The Intel non-commercial software program was recently rebooted. See https://software.intel.com/en-us/qualify-for-free-software for details.
