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.<br>

<div>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?</div>

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