There's a couple reasons for us: 1. Users (generally out of ignorance) will just run whatever they want via SSH, rather than reserving resources.
2. Their processes are not guaranteed to end with the job We don't do a lot of MPI, but tight integration was even easier to get going than loose integration because we didn't have to worry about getting users setup for passwordless logins since UGE handled the process startup/teardown.
