I'm afraid we did PSR a long, long time ago -- I don't remember the
exact history, but OpenPBS was the dominant version of that scheduler
genealogy at the time (this might have been before Torque existed...?
I don't remember the exact sequence of events back then).
Unfortunately, the work was never forward ported to Torque. If
Torque's internal architecture is similar to that of OpenPBS (and I
honestly have no idea if it is or not), then it shouldn't be *that*
hard to port it forward...?
I have dim recollections that as part of PSR we had a patch on top of
OpenPBS -- little bits in the daemon here and there, etc. But the
overall patch was fairly small, and (IIRC) dealt with obtaining AFS
tokens upon job startup. It shouldn't be that had to find the Right
places in Torque to do the same things -- there might even be better
ways to do the same kinds of things these days (e.g., if Torque has
authentication hooks available). And now that Torque has a healthy,
active development community, it might even be possible to get such
changes submitted upstream (I don't remember why we didn't submit the
PSR OpenPBS stuff upstream back then; perhaps there was no active
community at the time...?).
