We are in the process of converting our clusters from MPICH to OpenMPI
and have encountered some odd problems. For historical reasons, the
default shell we install for users is ksh. The --profile option to
mpirun does not work for our users under ksh. We are unsure why
although our system administrator believes that OpenMPI may be making
the ksh on the remote nodes believe that it's a login shell. We've
tried both rsh and ssh. Has anybody seen anything like this?

There are no problems at all under bash. (I use bash and I had no
trouble, but then started switching some users who were having MPICH
problems and they could not get it to work unless they changed to bash.)
