Nathan, Thanks for the help. I can run a job using openmpi, assigning a signle process per node. However, I have been failing to run a job using multiple MPI ranks in a single node. In other words, "mpiexec --bind-to-core --npernode 16 --n 16 ./test" never works (apron -n 16 works fine). DO you have any thought about it?
