Present: Joanne Bogart, Toby Burnett, Johann Cohen-Tanugi, Richard Dubois, Berrie Giebels, Navid Golpayegani, Traudl Hansl-Kozanecka, Heather Kelly (mute), Michael Kuss, Sean Robinson, Tracy Usher
ICQ non grata: (Richard) Goddard has taken to blocking ICQ. Meanwhile Navid is able to use it via U. Maryland. Steve Ritz will see about lifting the restriction, but if this fails a proxy server at U. Maryland is a possible work-around.
ROOT memory problems: (Richard for Ursula) Ursula is looking into leak and/or fragmentation problems which prevent us from reading large (1 million+ events) datasets. No progress yet.
Fuzzy clustering: (Richard for Gabriel) It's working on Linux and is about to be committed. Gabriel has no way to test on Windows; Richard will give it a shot. It has been implemented as a private tool, our first.
EM and GlastRelease: The latest GlastRelease (v2r2) doesn't contain everything needed for EM data analysis. In particular the latest EM geometry has not been tagged. Joanne will talk to Xin to confirm that it is ready to be tagged. We should then think about tagging GlastRelease v2r3 early next week. Everything appears to be in order in the nightly builds.
Nightly builds Windows port: (Navid) The plan is to duplicate nightly builds and system tests on Windows, using as much as possible of the existing Linux scripts. It's close to ready to go, waiting on some consultation with Alex and Karl. Output (Windows binaries and system test output) will reside in nfs space. We hope to be able to use these pre-built binaries via Samba just as the pre-built Linux binaries may be used.
VCMT repairs: (Toby) setup.bat is now generated for the correct tag (e.g. VC7) in all cases. A problem with clogged output has been fixed.
G4 and multiple scattering: (Richard) Still awaiting resolution on this. SLAC G4 guys have reproduced the 25% shortfall seen by Johann using his new G4TestAlg package. We will probably want to to go version 5.2 as soon as it's available. [post-meeting update from Richard: "I got a note from Makoto Asai that they think they found the problem and the fix will be in a patch shortly. Tatsumi Koi is to try it out at SLAC."]
FRED: (Richard for Riccardo) With the latest refactoring, it will be possible to use FRED directly from Gleam. Next up: ability to use it from ROOT, with FRED invoking Gleam as intermediary (since it already knows how to produce HepRep).
gcc 3.2 and Gaudi: (Johann) With a little work, the new version of Gaudi does indeed support gcc 3.2. It required a patch of Gaudi itself to compile and two or three patches of our stuff to be compatible. Then GlastRelease v2r2 of Gleam builds and runs. A suggestion was made that we run a system test or two and compare.
Glast Random Service: (Toby) In test_Gleam output for GlastRelease v2r2, but not v2r1, there are a series of complaints from GlastRandomSvc, perhaps signifying unwanted sharing, similar to this one:
WARNING Previous engine (0x891c270) for FluxSvcRandom was also set for G4GeneratorRandom
Chaining input: We need the ability to accept a list of input files. Richard has asked Heather to look into this. She doesn't think it will be too difficult to do.
Calibration news: (Joanne) Online folk are attempting to use the EM calibration files Leon made. After some email exchanges, they may be on their way.
At Seth's request, Joanne recently added two columns to the metadata table to keep track of starting and ending timestamp when the calibration in question was labeled "production". She also added a new table called history to keep track of such structural changes to the metadata table. Entries to history must be made by hand by the responsible party.
Action Items 
in minutes from 11 Feb is to make Tracy's
