Present: Heather, Ian, Joanne, Richard, Thomas, Toby, Traudl
Core summary : See http://www-glast.slac.stanford.edu/meetings/core_status20010124.htm, especially for details on status of the new GUI and 3-d display within the Gaudi framework.
Balloon items: Heather is involved with the balloon format converter. So far subsystem people have indicated there will be no real changes from beamtest, so making an appropriate version of RootWriter should be straightforward.
The balloon instrument is scheduled to take cosmics on March 5, something which JJ finds funny. One can conclude that it won't be any earlier than March 5.
Gaudi associators: Traudl has been working on this. She will be producing some tutorials particularly slanted towards our needs. (The ones available from the Gaudi project and from Atlas are complicated and involve facilities irrelevant to us.) She is also putting together some code using associators, but has run into technical difficulties which will probably be overcome soon after some consultation with Toby and Heather.
G4 work: Masanobu reports that he has made progress in tracking down the memory leak associated with the new hit classes and expects to have it resolved soon. Next he will embark on making G4 available as a Gaudi service.
Digis: Leon and Tracy are working on concrete digi classes for tracking.
Generic XML geometry status: See http://www.slac.stanford.edu/~jrb/glast/xml/geoStatus/24jan01.html for a first pass at breaking down the work to be done and some details on changes to the xml format to enhance maintainability and documentation. It is important to pin down how much effort will be required to get this in shape for the PDR runs.
GlastGaudi_co: Thomas has released a version with all the most recent developments except Toby's GUI work. It needs to be verified that it builds and runs successfully on Linux. It is not yet necessary to verify that releases work on Solaris. Most likely a still-newer release of GlastGaudi_co incorporating the new GUI and graphics will be available within a day or so, at least for Windows.
Root n-tuples: Ian has reached an impasse and is awaiting help from Root developers.
PDR: Peter has made it abundantly clear that the PDR is crucial as it will result in a go/no-go decision on GLAST. In order to generate supporting data in time we will need to freeze the code by the end of May. In addition to the obvious (being far enough in code development to support all the functions needed) we also will need to
validate the code, presumably with the same sort of tests used for the AO code
provide support for analysis platforms (Root, IDL)
verify that adequate disk, CPU, etc., resources will be at hand when we need them
Juggling balloon support with the PDR work won't be easy; both are required, though we can probably get by with less-than-perfect balloon support (as happened for the beam test).
