分享关于AMD的
我现在用的CPU是AMD的，我想请教一下专家，假若我在此CPU上运行用Intel的编译器编译程序，是不是性能不可能有什么提升， Intel 的编译器是否在一定程序上兼顾AMD的用户，我要利用Intel编译器做开发，是否必须转移到Intel平台上来，我又怎么样才可以开发出不管在Intel平台上还是在AMD平台上性能都很好的程序，主要是多线程程序。很期待专家的回答，问得不科学，期望批评指正。

在"英特尔软件开发工具技术文章索引"中, 有一篇讨论英特尔C++编译器中针对处理器优化的文章, 可以参考一下 http://topic.csdn.net/u/20080402/15/2bd8d20e-c887-46a2-9afd-5fd5b75474aa.html

完全支持的, 也可以得到性能提升.
具体的回答参考 FAQ 原文: http://support.intel.com/support/performancetools/sb/CS-009787.htm
Does Intel test the Intel® Compilers on all processor types including non-Intel processors?
A: We cannot test on all processor and platform combinations, but we do perform extensive testing and benchmarking on many platforms that gives us confidence that our optimizations, like /O2, /O3, /Qipo, profile guided optimizations using /Qprof_use (-O2, -O3, –ipo, -prof_use on Linux and Mac OS), and other processor independent compiler options, work well on all Intel processors and Intel compatible processors. Processor values O, W andK are tested on various Intel and non-Intel processors. The processor-specific compiler options like [S, T, P, N] are validated only on those specific Intel processors. These options enable the latest and best optimizations to target Intel's latest and best processors.
Does Intel offer customer support for Intel Compilers used on non-Intel processors?
A: Yes. Intel will accept problem reports and fix issues reported on non-Intel processor-based systems.
