Hi

On many machines you have those two devices (shmem and p4) available
for communication (shmem can be used only for SMP machines). Sysadmin
usualy gives you the choice over which one you prefer so both are
installed, generaly in dfferent path. Then Your choices have to be
consistent. If you compile with
/any/way/p4/bin/mpif90
you must run something like
/any/way/p4/bin/mpirun -np ...
and not
/any/way/shmem/bin/mpirun -np ...
and vice versa.
I think that something like that may be the reasons for the error
message you get, isn't it.
regards

PMA
