if you're after full PBS integration of the MPI, then LAM and OpenMPI
already have that built in (eg. at configure time, --with-tm=/opt/pbs),
but MPICH1 wasn't PBS aware, and hence the mpiexec hack. I'm not sure
about the status of MPICH2, but it doesn't matter as OpenMPI is the
future anyway.... :-)
eg. for CentOS4.4/OSCAR5's version of OpenMPI:
% ompi_info | grep tm
MCA memory: ptmalloc2 (MCA v1.0, API v1.0, Component v1.1.1)
MCA ras: tm (MCA v1.0, API v1.0, Component v1.1.1)
MCA pls: tm (MCA v1.0, API v1.0, Component v1.1.1)
does that help?
perhaps you want mpiexec for some other reason?
cheers,
