[Condor-users] Extending Condor's scheduling? (for sched. researchpurposes)

[David Petrou <dpetrou@xxxxxxxxxxx>]

Hello.  My name is David Petrou and I've designed novel scheduling 
algorithms for speculative tasks for my thesis at CMU.  (pls. reply 
offline if interested in details.)

Simulation results are promising.  I would like to make a 
proof-of-concept implementation for Condor to demonstrate these ideas 
in the real world.

I am wondering what the easiest way would be to take over Condor's 
scheduling policy.  I understand how user priorities strive for 
long-term fair-share among users.  So, it seems that if I can hijack 
Condor's computation of priorities, I could determine how things are 
scheduled among users.  Further, if I could do the same for job 
priority, it seems like I'd have control among a user's jobs as well.

Alternatively, I am wondering if there is some way to extend Condor's 
scheduling, perhaps via a library, so that I can bypass priorities 
altogether and simply have Condor call my own functions when trying to 
determine what job should run.

Someone must have tried extending Condor's scheduling before, but I'm 
coming up empty.  Pointers to a fast-path to integrating my own 
scheduling logic into Condor would be greatly appreciated, 
acknowledged, and research results shared.

Thank you very much,
david
