Are NODES and NODELIST the only env vars that BProc uses (I gleaned this info from http://asci-training.lanl.gov/BProc/)? MTT is set up to detect environment variables and hostfiles used by Slurm, PBS, N1GE, and LoadLeveler and set a max value for -np based on those env vars. While we add the smarts to MTT to do that for BProc, you could also hardcode the -np value (e.g., 2) in your ini's "MPI Details" section like so: exec = mpirun @hosts@ -np 2 --prefix &test_prefix() &test_executable() &test_argv() Thanks, Ethan > Thanks, > Jim Barker > > James W.
