sPHENIX is a new detector at RHIC.

Hi all,

 

When working on the EMC clustering I  was experiencing something similar since before the collab mtg. Since then we’ve been avoiding work needing high statistics, and hoping I could eventually just solve the issue by turning off something, like the tracking since I don’t need it.  Will that or something similar (please suggest?) work to just lower the mem usage (and thus benefit from more available machines)?

Hi Chris,

 

I am running some central Hijing jobs now, and it looks like quite a few are failing. Do we have to request the new queue specifically?

 

I think 30 GB should likely be enough.

 

Thanks

Tony

Hi folks,

we just adjusted the highmem queue parameters. It now lets jobs grow to
30GB before evicting them (if someone could give me some idea if this is
enough I would appreciate it). On the downside the number of condor
slots is drastically reduced since only a subset of our machines can run
something like this (one job on 64+GB memory machines, 2 on 128+GB machines)
