Hello,
I've seen before that some of you have been mentioning Agner Fog's VCL library (http://www.agner.org/optimize/#vectorclass) as a very good alternative for dealing with ICC intrinsics directly. I have made an extension for that library to be able to run the function templates on Knight's Corner. Please feel free to use it and comment. The implementation is not yet fully compatible with AVX512 implementation from VCL, but most of the basic operations works well.
The extension is available at: https://bitbucket.org/veclibknc/vclknc
Kind regards,
Przemek.
