Hi,
If you have a batch system that can start the MPDs, you should
consider starting the MPI processes directly with the batch system and
providing a separate service to provide the startup information.
You're exactly right. Intel's MPI is derived from MPICH2 and (as we use
PBSPro) OSC's mpiexec should do that job nicely, starting the MPI
processes via PBs's TM API and then speaking to them via PMI. However,
since version 2.0.1 refresh 1, Intel have used a modified (and
incompatible) PMI command set for which documentation hasn't been
forthcoming. Lacking the time to hack about, we've had to revert to
using their mpd for the time being.
