[mvapich-discuss] Intel Complier Flags and mpicc, etc.

[Novosielski, Ryan]

Hi there,

This question probably has a simple answer but I’m not seeing it in the documentation. I’m attempting to compile some MPI-aware software that will work on nodes with two different architectures. Intel’s compilers have something called auto CPU dispatching, and apparently can build code that works on multiple different types of processors if you specify the -ax flag and which architectures. However, mpicc and friends balk at this command line option. What is the right way to address this sort of thing? I’m using the Intel compilers v15.0.1 and MVAPICH 2.0, if it matters.

Thanks.
