[mpich-discuss] Hydra launching on CPU+MIC?

[Jeff Hammond]

Is there documentation somewhere for how to launch Nh MPI processes on
the host and Nm MPI processes on the MIC using Hydra?  TACC told me
that Intel MPI's Hydra supports this so I guess MPICH's does as well
but I'm not sure how to do it.

I only care about launching on a single box right now, not a cluster,
so interactions with multiple nodes, IB, etc. don't matter to me.

And when I run in this mode, I will be using Nemesis shm within the
host and within the MIC while using SCIF between them, right?

Thanks,

Jeff
