I assume you are running in a non-managed environment and so are using
ssh for your launcher? Could you tell us what version of OMPI you are
using?
The problem is that ssh drops you in your home directory, not your
current working directory. Thus, the path to any file you specify must
be relative to your home directory. Alternatively, you can specify the
desired current working directory on the mpirun cmd line. Do a "man
mpirun" to find the specific option.
I'd have to check, but we may have corrected this in recent versions
(or a soon-to-be-released one) so that we automatically move you to
the cwd after the daemon is started. However, I know that we didn't do
that in some earlier versions - perhaps in the 1.2.x series as well.

Hi
I am trying to get a parallel job of the gromacs software started.
MPI seems to boot fine but unfortunately it seems not to be able to
open a specified file although it is definitly in the directory
where the job is started. I also changed the file permissions to 777
but it does not affect the result. Any suggestions?
cheers

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode -1.
NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

mpirun has exited due to process rank 0 with PID 3777 on
node 192.168.0.103 exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).
