sPHENIX tracking discussion

[Anthony Frawley <afrawley AT fsu.edu>]

Hi Christof,

Over the weekend I have been running 2000 jobs at a time with central Hijing+ 100 pions + 1 upsilon. About 1400-1500 of them do not reach the 20 GB limit and finish within ~ 1.5 hours. Of the rest, some crash (~50), ~250 are put on hold when they get too big, and ~ 200 are running but are just taking too long. So after ~ 1500 jobs finish I "condor_rm" the rest and start another 2000.

It is not very satisfactory, but I need to get these done so I can make performance plots that are needed now. We need to solve the clustering issue pointed out by Sookhyun, since that is likely the problem.

Tony

Subject: [Sphenix-tracking-l] Did anyone manange to run Hijing lately?

 

Hi Everybody,

even with the more recent change to the TPC macro I am still having trouble running Hijing events.
The jobs blow up to 20GB and then just hang. These are jobs that just do run simulation up to cluster
level and then write to disk.

Did anyone mange to run any hijing events to the end lately?

Also in the log file root throws an error:
Error in <TBufferFile::WriteByteCount>: bytecount too large (more than 1073741822)
Has anyone seen these?

Thanks for your input

   Christof
