JLab Farm Priority
Paul asked if there was a special account. one that gets increased priority, that we could use, like the production accounts in CLAS (e. g., clasg13). Mark noted that those accounts are enhanced only relative to other CLAS users. There is still an overall allocation per Hall. Hall D's allocation is currently 4% no matter how we split it up internally.
More broadly, Mark promised to research how the current scheme is executed in detail. His memory of these details are from the old LSF days.
JLab Farm Mini-Challenge Status
Mark showed the summary statistics from the now-completed mini-challenge which was producing REST formatted data. There is still a poor yield (79%) of output files produced by a job, and that in fact not all of those were complete. The outstanding memory issue has not been addressed, however.
Large, Usable Pythia Sample
We discussed the idea, endorsed at the collaboration meeting, of making an effort to generate 2 billion Pythia events on some combination of our current resources. Mark outlined some of the issues. We also discussed Richard's recent email describing software changes he advocates before we get started.
