Core Minutes 1/27/2004

Present: Pol d'Avezac, Ursula Berthon, Joanne Bogart, Toby Burnett, Jim Chiang, Seth Digel, Richard Dubois, Dan Flath, Berrie Giebels, Navid Golpayegani, Traudl Hansl-Kozanecka, Heather Kelly, Michael Kuss, Matt Langston, Julie McEnery, Pat Nolan, James Peachy, Leon Rochester, Alex Schlessinger, Tom Stephens, Tracy Usher

Core status: (Toby, Heather,..)GlastRelease v4r0 is tagged and and builds on both Linux (at SLAC) and Windows (UW terminal server). There are still some issues to be resolved with the new versions of external libraries. Matt is packaging them for Windows (7.0 and 7.1 only). Alex will do it for RH9/gcc 3.2 and for RH7/gcc 2.953. See also Toby's page.
New Release Manager: (Alex) As of last night, expect to use it to regularly make builds for both RH 7.2/gcc 2.95 and RH9/gcc 3.2 environments. Emails about errors will go out to package owners for both builds. The value of cmtconfig will be in the subject line. When we are ready to move to RH9/gcc 3.2 as preferred configuration web links will be adjusted accordingly. (Toby) Can't we at least switch to gcc 3.2 everywhere? (Berrie, Alex) Lyon is going to stay at RH7 for a while yet. It will move when and where Babar does. That probably means to Enterprise (which probably comes with gcc 3.2) in some small number of months. Meanwhile, Berrie has asked for a couple RH9 boxes. He hasn't gotten back a reply yet. In previous attempts Alex has been unable to make gcc 3.2 work on RH 7.x machines to the extent of running GlastRelease.
OPUS: (Dan) It's working with DataChallenge package. 4 vectors are being generated, sim/recon gets done. When Alex's database is ready (expected soon) it will be interfaced to OPUS. Work on wrapper scripts to access the database is in progress. Also coming up is the addition of another pipeline stage to run RootTreeAnalysis, web pages for monitoring and management, and all remaining items on last week's to-do list.
Astroroot for Windows: (Navid, Heather, Berrie) He did the conversion, but Heather has had problems trying to use the command-line executables which are part of the package. She hasn't yet tried using (interactive??) Astroroot directly. Berrie cautioned that input FITS files must have the correct extension or Astroroot can't read them, however this is not the problem Heather has run into.
Data server: (Navid) It now includes the root files from backgndavgpdr-v3r3p7 and some BGEfiles that Berrie had uploaded.
Eclipse: (Navid) Has run into a roadblock. Eclipse doesn't understand our requirements files. It can deal with the makefiles, but this is not sufficient for all anticipated uses.
Science Tools architecture : (James) Not much to report since last Thursday's general meeting other than snow.
PyROOT: (Johann) He has gotten it to build, though it was not easy. You can read more about his experiences to date here. Presumably PyROOT and GaudiPython could co-exist so that Python aficionados could work in a Python-only environment.
Geant 4 v6: (Tracy) There is no rush to move to a newer version, but someday we will move so it is just as well to lay the groundwork. Tracy is able to build it with no errors (plenty of warnings, though). He had to make several changes, particularly to G4Generator (to accommodate changed Run Manager interface) and to G4Propagator and also minor changes to GlastMC. The multiple scattering problem is still not fixed in this version.
CMT release area: (Traudl) It's ready for people to try it out. See her description of what it's all about and how to use it.
RootCnvSvc: (Ursula) She is making good progress with the code to convert additional TDS objects. No new ideas yet on the loading problem.
Xerces conversion status: (Joanne) Stage 1 (enhancing the xml package and modifying other packages to use the new methods there rather than native Xerces calls whenever possible) is moving right along. xml, xmlUtil and detModel are ready or nearly so. There are still several more xml-using packages to be dealt with, some of which belong to other people. Within a week or so Joanne will write up something to aid them in making the conversion, and at about the same time should be starting on Stage 2: use of Xerces 2.4.
DC1 closeout: (Richard) Don't forget: it's scheduled for Feb. 12-13. Visitors are encouraged to stay the whole week if possible.

Action Items

Document effect of MC pruning options (Riccardo) (8/5/2003) It's documented in the code; Tracy will look into putting the information in a more accessible place. (9/2/2003)
Write up, and perhaps present at a future meeting, hints on debugging. (02/18/03) Some combination of Toby and Tracy will provide something for Windows.(7/22/03)
Overhaul documentation altogether by about November (Heather and ??) (9/2/2003) In progress; not yet done (01/13/04)
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) Now that events have "real" timestamps, Joanne needs to reassess situation with Calibration (9/2/2003) Timestamp exists in EM data. Needs to be fetched by Calibration (1/13/04)
