With the options I used to configure, mpiexec / mpirun are not built or installed (presumably due to SLURM interface).

Michael,
Did you try just using mpiexec?
mpiexec -n 32 /usr/local/apps/cxxcpi

Hi All ~
I've compiled MPICH2 3.0 with the Intel compiler (v. 13) on a CentOS 6.3 x64 system using SLURM as the process manager. My configure was simply:
./configure --with-pmi=slurm --with-pm=no --prefix=/usr/local/apps/MPICH2
No errors during build or install. When I compile and run the example program cxxcpi I get (truncated):
$ srun -n32 /usr/local/apps/cxxcpi
Fatal error in PMPI_Reduce: A process has failed, error stack:

This error is experienced with many of my MPI programs. A different application yields:
PMPI_Bcast(1525)......: MPI_Bcast(buf=0x7fff545be5fc, count=1, MPI_INT, root=0, MPI_COMM_WORLD) failed
MPIR_Bcast_impl(1369).:

MPIR_SMP_Bcast(1077)..: Failure during collective
Can anyone point me in the right direction?
Thanks,
~Mike C.
