Are NODES and NODELIST the only env vars that BProc uses (I
gleaned this info from
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
exec = mpirun @hosts@ -np 2 --prefix &test_prefix() &test_executable() &test_argv()
