OK, I added those, but got a message about needing to supply a suitable
debugger. If I supply the "--debugger gdb" argument, I just get dumped
into gdb. I'm not sure what I need to do next to get the launcher
output you mentioned. My knowledge of gdb is pretty rudimentary. Do I
need to set mpirun as the executable, and the use the gdb "run" command
with the mpirun arguments?

Do I need to rebuild openmpi with --enable-debug?
