I do see a diff between 2.0.1 and 2.0.2 that might have a related impact. The way we handled the MCA param that specifies the launch agent (ssh, rsh, or whatever) was modified, and I don’t think the change is correct. It basically says that we don’t look for qrsh unless the MCA param has been changed from the coded default, which means we are not detecting SGE by default.

Try setting "-mca plm_rsh_agent foo" on your cmd line - that will get past the test, and then we should auto-detect SGE again

Ah-ha! "-mca plm_rsh_agent foo" fixes it!

Thanks very much - presumably I can stick that in the system-wide openmpi-mca-params.conf for now.

Cheers,

Mark
