For what you are talking about (exclusive access to systems or
allowing users to consume more than 1 slot/cpu per task) the most
common implementation I've seen involves using Grid Engine parallel
environment objects in clever ways. This was written up in the past
The "threaded PE" model can be used for both of your examples --
letting someone get full use of a system or letting someone "consume"
what is effectively more than one CPU/jobslot for a single task.
As a random side note I know of a group that will be running an LSF-to-
SGE migration workshop in mid-March of this year in California. Once I
get the full workshop details I'll post them.
