I'd appreciate an opinion on whether the problem is in OpenMPI or not and
what's the best way to proceed.

ns I'd like to
hear the numbers.
Thanks again for all the work. Openmpi looks very promising and it is
definitely the easiest to install and get running of any MPI implementation
I have tried so far.

Furthermore if attempt to start with the mpirun arguments "--mca btl
gm,self,^tcp" the run aborts at the MPI_INIT call.
Q1: Is there anything else I have to do to get openmpi to use gm?
Q2: Is there any way of diagnosing which btl is actually being used
and why? None "-v" option to mpirun, "-mca btl btl_base_verbose"
or "-mca btl btl_gm_debug=1" make any difference or produce any
more output
Q3: Is there a way to make openmpi work with the LSF commands? So far
I have constructed a hostfile from the LSF environment variable
LSB_HOSTS and used the openmpi mpirun command to start the
parallel executable.
Sincerely
Keith Refson
