Martin, For the MIC build, you'll just need to pass CFLAGS=-mmic. You didn't give enough information below to say what went wrong. -- Pavan On 03/19/2013 02:26 AM US Central Time, Martin Rose wrote:

Dear all,

I want to run an MPI program on an Intel Xeon Phi accelerator (MIC). I want to use an open source MPI library but I have not found any information about how to compile the MPI library for MIC.

The link below leads to a paper about MVAPICH2 on MIC but the paper does not talk about compilation of the library. http://nowlab.cse.ohio-state.edu/publications/conf-papers/2012/potluri-tihpc...

I have tried to compile mpich-3.0.2 with icc anf ifort using a -dmmic as dummy flag. After running config, the dummy flag is replaced by -mmic. This got me pretty far but I do not have libnuma for MIC so the compilation could not complete.

The announcement of MPICH2-1.5 states that the MIC architecture is supported. http://www.mpich.org/2012/10/08/mpich2-1-5-released-oct-8-2012/

Can anyone describe the build process to run a program compiled with MPICH on Intel MIC?
