[mpich-discuss] Does MPICH support launching processes on Intel-MIC from host?

[Yida Wang]

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.
