We managed to have another user hit the bug that causes collectives (this time
MPI_Bcast() ) to hang on IB that was fixed by setting:
btl_openib_cpc_include rdmacm
My question is if we set this to the default on our system with an environment
variable does it introduce any performance or other

Something like this (for a 64-bit machine):

You need to compile your cpi.c to get an executable. This is not an MPI issue.
:-)
Also, mpdboot is part of a different MPI implementation named MPICH; you don't
need to run mpdboot with Open MPI. If you have further questions about MPICH,
you'll need to ping them on their mailing list -- we
