Core Minutes 8/26/2003  

Present:   Joanne Bogart, Toby Burnett, Xin Chen, Richard Dubois,  Berrie Giebels, Navid Golpayegani, Heather Kelly, Matt Langston, Dirk Petry, Leon Rochester,  Tracy Usher

• DC1 news: (Richard)  See the current version of the Project file.

  • (Navid) The last OnboardFilter task, making Filter-found tracks available in TDS, is in progress and will probably be finished today. 

  • (various) Problems Heather encountered in the rush to get a new all-gamma data set to Bill will, it is believed, disappear as soon as a compatible set of packages, probably the ones now in HEAD, are tagged as GlastRelease v3r3p1.

  • (Toby) CRFlux coding is done, but is not fully tested.  Ditto for GlastRandomSvc.

  • (Leon) n-tuple documentation is proceeding, now on 2nd iteration.  At last count there were 210 variables in the n-tuple.

  • (Richard) Goal for the Pipeline is to have something in place by the end of September which can handle 1 million events. Dan and Alex now have an intermediate goal: to have a design and demonstrate feasibility with at least a trickle of events in three weeks. Meanwhile, Berrie is looking into providing an additional pipeline in Lyon to handle part of the processing.

  • (Richard) If we trust the OnboardFilter implementation, we end up with a dataset of about 100 Gbytes, an eminently manageable size. If we try to keep everything, it's 6 terabytes.  We don't have that kind of space currently and SCS probably does not have it readily on hand to give away; they would have to budget for it. Toby pointed out that the performance of the OnboardFilter can be evaluated with just a sample, and in any case that it is JJ's responsibility.

  • Related point, not mentioned during meeting: Toby is making a DataChallenge package to hold DC1-related configuration, etc.

• EM and EBF library: (Joanne)  Heather's additions for reading EM calorimeter data, completed a week or two ago, are tagged but not yet in GlastRelease HEAD. Meanwhile, we have not kept up with the Online EBF library, which had a major release about a month ago and lesser releases since. See this status page for more details.

  The full EM, including calorimeter, is just beginning to produce data.

• Infrastructure wish-list: Any more suggestions beyond this list? Will schedule a meeting shortly.

• Extra-curricular: We can all bask in Tracy's reflected glory.

  Action Items 

• Document effect of MC pruning options (Riccardo) (8/5/2003)
• Reorganize RootAnalysis package so structure is more standard.(05/13/03)
• Write up, and perhaps present at a future meeting, hints on debugging. (02/18/03)   Linux document exists, needs to be linked in somewhere. Some combination of Toby and Tracy will provide something for Windows.(7/22/03)
• Resolve calibration/timestamp issue. (11/20/02) Online folk have not yet thought about putting timestamp information into EM data, but, thanks to Richard's inquiry, may now do so. (2/25/03) We can probably live without a realistic system for EM, but we will put it on the agenda for the DC1 workshop.(5/6/03) At the DC1 Workshop Steve Ritz  promised to find an authoritative reference for timestamp format and pass it on. (7/17/03) 
• We need a web page on the workings of the Release Manager (Alex) (5/6/03)
