Does the same failure if pre-compiled OpenMPI used?
Yes - that is what I meant by running HPC-X
Did you try to avoid LSF and run mpirun directly? Maybe allocate nodes used
LSF and the from the other terminal run the MPI job.
No I did not try that. What kind of incompatibility between LSF and libmxm
are you suggesting would demonstrate the behaviour I see?
Try to add LD_LIBRARY_PATH path to mpirun command, something like mprin -x
LD_LIBRARY_PATH
That is how I always run. It is the only way to be at least somewhat
certain what is going to be used during execution.
It is also the only way to be able to have several different runs with
different set-up queued and be able to know the
circumstances on how they were executed.
