I've discovered that under RHEL 5 orted gets spawned via qrsh and under RHEL 6 orted gets spanwed via SSH. This is happening in the same cluster environment with the same parallel environment setup. I want orted to get spawned via qrsh because we impose memory limits if a job is spawned through SSH.
Is it spawned by SSH directly or as a result of `qrsh -inherit ...`, while:
$ qconf -sconf
is set in the old cluster but different in the new one (i.e. pointing to SSH there)?
