Intel Compiler AVX Instructions

[inteleverywhere]

The option QxAVX (for using AVX instructions) is not available with the evaluation version of the ICC compiler 11.1065, vs 2008.Also the header file gmmintrin.h mentioned in the help is not available when included

catastrophic error: could not open source file "gmmintrin.h"

How can we build the source with AVX intrinsics in it. Is it sufficient to use o3 (Intel specific optimization).
Is there a solution to this problem.

Please see my answer in the AVX forum.

In assessing the extent to which AVX is supported for Windows in the near future, it's probably useful to check Microsoft web sites, e.g. http://msdn.microsoft.com/en-us/library/ff545910%28VS.85%29.aspx
Apparently, there is support for driver programming, but I don't find any official announcement about time frame for Win7 service pack to provide full AVX support.
Note the explicit prohibition against interrupt servicing with AVX registers.
Ke ExtendedProcessorState function calls are optional in X64 xmm register usage but mandatory when using AVX. I wonder if these requirements may apply to user level AVX until an appropriate service pack is available.
