Core Minutes 3/9/2004  

Present:     Ursula Berthon, Joanne Bogart,  Toby Burnett,  Jim Chiang, Richard Dubois, Berrie Giebels, Navid Golpayegani, Heather Kelly, Traudl Hansl-Kozanecka,  Matt Langston,  Julie McEnery, Pat Nolan,  Tom Osborne, James Peachey, Leon Rochester, Robert Schaefer, Alex Schlessinger, Tom Stephens

• Core issues and status: (Toby) See a run-down of issues of interest here and follow-up on some of them below:

  • The "new throttle in Trigger" is work of David Wren and concerns the ACD.
  •  [Latest from Tracy, post-meeting, is that almost all the 160 GeV "crashes" are the result of bumping up against resource limits in the batch queue, which can take effect somewhat differently depending on precisely which machine the job was submitted to. ed.]
  • param_gui doesn't currently work on Windows, which would have to be remedied before it could be a standard part of the Science Tools environment.  However, Jim Chiang has a Python implementation which should work on both platforms.  Toby will check it out.
  • (Alex) Windows Release Manager is just about ready to go.  There was a problem with the last attempt which Alex understands and should be able to fix.
• Who's doing what: (Richard) See the comprehensive picture and more detail on support for flight integration. If anything has been left out, Richard would like to know. Berrie mentioned the farm at Lyon which is a bit of a step-child since the Lyon batch system is still at Redhat 7.2, and will probably move soon to some as-yet-to-be-determined Linux version.

• System Tests: (Julie) She found and fixed a bug which made it impossible to add a new test.  She would like to change the definition of "vertical" (as in "vertical protons" and "vertical gammas"; muons will be left as is) to mean coming from a disk rather than a pencil, since for diagnositics measuring instrument performance, pencil beams are overly sensitive to geometry.

• System Tests: (Matt) A major reorganization is in progress, ultimately to involve ColdFusion as a means to provide the application's web interface. Compare the old database schema (click on the RecordInfo link to see all the redundant fields which could be eliminated) and the new one.

  The System Tests consist of three logical stages: Configuration, Running, and Display.  In the new arrangement, the first two will be handled by the Processing Pipeline. It will be relatively easy to add a new system test. Histogram definitions have been moved to the database (rather than, for example, being buried in root macros). A histogram comparison facility is also part of the new scheme.

  Database design is close to stable.  Next step is to write some (Oracle) stored procedures, and then layer on the Web interface.

• Install area: (Traudl) There was not time for Traudl to bring us fully up to date on the status of her work on the Install Area; she will discuss it more fully next week, either at this meeting or at a smaller one for the true aficionados. You can find just about everything she talked about and more in her write-up. Things are in reasonably good shape for ScienceTools; there are more wrinkles to be addressed for the more complicated GlastRelease. So far she has been building just in a private area; it is time to put her install area in a public place where package owners can easily examine the results for their packages.

• Congratulations to the new GLAST Mission Scientist, Julie!

  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)
