Core Minutes 11/30/2004  

Present:    Joanne Bogart, Toby Burnett, David Chamont, James Chiang, Johann Cohen-Tanugi, Seth Digel, Richard Dubois, Warren Focke, Navid Golpayegani, Heather Kelly, Matt Langston, Francesco Longo, Julie McEnery, Chuck Patterson, Leon Rochester, Tom Stephens, Tracy Usher

• RM news Thanks to a timely patch by Navid LATEST builds will now accept tags similar to v1r7p3gr1. This has eliminated most but not all compile errors we've been seeing in LATEST.

  Navid has determined that it would take considerable effort to reinstitute automatic optimized builds in the old RM. Instead, he will make them manually for tagged releases (he recently made one for GlastRelease v4r6), meanwhile working on the new RM. He knows of no other pending requests for old RM.

• System tests (Julie) She will be running tests on v4r7. In an attempt run them on v4r2 (at the time the latest version with an optimized build) she saw the memory usage go up to 2 Gig, followed by a crash in TkrDigiAlg.
• GlastRelease, G4 and TkrRecon: Richard proposes we make a first v5 GlastRelease tag including new G4 but not new TkrRecon, to be followed shortly thereafter by v5rX including the new TkrRecon. Francesco has been comparing histograms from old and new G4. So far, so good. Look for a final report at next week's Analysis Group meeting.
• Nightmare on Root Street: (© Heather) Alas, although the build of Root v4.01.04 (version recommended for Windows by Root forum) kindly supplied by Navid works fine on Windows, test_rootIo produces the same old core dump on Linux seen with 4.00.08, but not with 4.00.08F. It seems to have something to do with our use of Gaudi. Still searching for the magic version that works everywhere.
• Pipeline: Planning on an MC run this week.
  • Matt needs to make some fixes to front-end: eliminate restriction on number of runs displayed; make links to log files. Goal is to have everything ready by tomorrow.
  • Dan is putting in his LSF log file fix; it was more complicated than expected.
  • Still need a solution to the limit (200) on concurrent Oracle connections. Haven't been able to get around it with the program Alex found to do database pooling, nor with a Java tool which was supposed to handle it.
• Doubles or floats (Leon) Using all that space in our ROOT files for doubles rather than floats seems pointless. He proposes we make the code changes to write out floats instead. (Richard) This is to save space in files. What about TDS representation? We could leave that alone. (Leon) We might want to use floats in the TDS as well for reproducibility, so that event data is the same whether it's generated in your process or read in. Toby is also in favor of switching to floats. Discussion to be continued next week.

Coming Soon

Navid, Heather and David will all be visiting SLAC next week, providing good opportunities for discussion of CalRecon and RM issues.
