Thank you! That works, but is not very convenient. Can I know why you guys don't configure mpich to behave as the same as Intel-MPI? Basically, using Intel-MPI, one can use the same mpiexec.hydra on both host and Xeon Phi.

For that, you have to deploy two installations of MPICH: one compiled for the host, and the other for the MIC. To make things easy, place them under the same path in both hosts - one that is not shared.

Hi Guys,

Can MPICH be configured to support launching processes on Intel-MIC from the host? I know that there's a way to compile MPICH to be running on Intel-MIC only, but how about running heterogeneously on both host and Intel-MIC together?

My compiled version returned "hydra_pmi_proxy: cannot execute binary file" and got stuck when I tried to launch processes on Intel-MIC.

Thanks,

YW
