Thank you! With the patch, --preload-binary option is working fine. However, if I add "--gmca plm_rsh_no_tree_spawn 1" as a mpirun command line option, it hangs.
# /mpi/bin/mpirun --allow-run-as-root --gmca plm_rsh_no_tree_spawn 1 --preload-binary --hostfile /root/.hosts --prefix /mpi --np 120 a.out If I ran the command without --preload-binary, it works fine (have to copy the binary to each node beforehand of course). I guess this is a different issue?
