[gridengine users] Evaluating different scheduler strategies by simulating a past workflow

[Fabio Martinelli]

Dear Sun Grid Engine colleagues

is there a way to apply again a past workflow by using information like 
that stored inside the ARCO DB, the reporting file or the accounting file ?

obviously with a shorter time scale and we don't mind about about memory 
consumption and I/O, just slots assignment.

basically we need to understand if the actual scheduler policy is 
"fair", at least according to our personal concept of "fairness";
so far it's unfair and as a reaction we should tune some scheduler 
parameters and observe the Sun Grid Engine behavior but as jobs take 
hours or days to complete this tuning process is simply to long to manage.

just to cite a concrete solution, I never tried this Moab Simulator
http://www.adaptivecomputing.com/resources/docs/mwm/6-1/Content/topics/analyzing/simulations.html
but the 'simulation' concept and the related tools seem to be there, so 
I wonder what about {Sun} Grid Engine.

I'm using 6.2-5 on Linux 64bit

many thanks,
best regards
