Dear gmxers,
We have installed gmx-4.5.4 on one cluster from the source, without
any errors. I can also run mdrun in non-parallel way successful.
However, when I run mdrun in parallel way as follows:
mpimdrun -h
some messages are given:
[node10:03709] mca: base: component_find: unable to open
/public/software/mpi/openmpi1.4-gnu/lib/openmpi/mca_btl_ofud: perhaps
a missing symbol, or compiled for a different version of Open MPI?

MPI? (ignored)
NNODES=1, MYRANK=0, HOSTNAME=node10
What does it mean by saying so? Could you give me some hints for
dealing with it?
Either linking to MPI isn't working, or MPI isn't configured correctly.
Try an MPI test program, or using static linking.
