- IU: Matt Shepherd
- JLab: Eugene Chudakov, Mark Ito, David Lawrence
- UConn: Richard Jones
Announcements
Mark reported that the Computer Center was given a heads-up that we will start working on the data challenge. Batch jobs will start to appear on the JLab farm. We will have a tape volume set that can be recycled.
Scope of this Challenge
- We agreed to continue on the course of using Curtis's document as a repository of our ideas about the data challenge (DC). Curtis agreed to convert document 2031 into a Wiki page. The page is now available asPlanning for The Next GlueX Data Challenge.
- Curtis reminded us that we need a robust storage resource manager (SRM) for the DC.
- Grid and JLab: Mark asked about whether we want to pursue large-scale production on the Grid, at JLab, or both. We decided to pursue both.
- Matt thought that a huge sample of Pythia data would be sufficient to address main goals of the DC. Physics signals are of a smaller scale and can be generated in a more ad hoc mannger.
- We talked about December or January as a tentative time frame for doing the first DC. In the future we will have to set-up more formal milestones.
Mini-Data Challenges
revised rest format
gridmake
consensus on rest format dcth to dttb big cost associated, 30 hz re-swim a track 1.8 freeze on that
Action Items
- Make a list of milestones.
