 Would like info on GR non-configurable properties  Help  Gridrepublic.org 11/16/11 04:11 am

Hello.

I would like information on what the following mean: Projects: CPU Scheduling Priority, Projects: CPU Work Fetch Priority, and how task CPU time estimates are calculated. Note: it would also be nice to put them in the GR user's manual.

GR once bumped up my POEMs to High Priority (I don't know why), then it stopped doing that. Does this control the priority eachproject gets in the CPU round-robin or does it actually control the task process priority or both?

I would guess CPU Work Fetch Priority is a measure the core servers use to determine how much work to feed your computer. Does it also control priority of projects versus other projects?

The third thing is CPU time estimates. I notice that POEM and Malaria seriously overestimate their time requirements,usually 50% more than needed and once 100x as much as needed (2 tasks had an estimate of 5 days each, they both ran in 2 hours), while Docking, WCG, and Rosetta seem to underestimate by 5-10% (probably due to me sucking up valuable CPU cycles typing at the keyboard andusing my mouse).

Thanks.
