Have you tried ssh to MIC and check mpiexec.hydra again ? It might
be different files just using the same path.<br>

<div>I don't have Intel-MPI, but is it really a binary

`file mpiexec.hydra` show?</div>

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>
