The Intel compilers can very well compile applications for Narval's AMD processors with the less recent AVX2 instruction sets. To do so, use the <tt>-march=core-avx2</tt> option to produce executables which are compatible with both Intel and AMD processors. | The Intel compilers can very well compile applications for Narval's AMD processors with the less recent AVX2 instruction sets.

However, the applications will not operate on Narval if your code was compiled on a system using one or more <tt>-xXXXX</tt> options such as <tt>-xCORE-AVX2</tt> because the Intel compilers add extra instructions to verify that the processor is by Intel. This beinig said, the <tt>-xHOST</tt> on Narval becomes the same as <tt>-march=core-avx2</tt>. | |||
