[mpich-discuss] MPI on Intel MIC

[Martin Rose]

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.

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.

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

Greetings,
Martin
