Core Minutes 5/24/2011

Present: Joanne Bogart, Anders Borgland, Toby Burnett, Jim Chiang, Stefano Ciprini, Richard Dubois, Elizabeth Ferrara, Warren Focke, Dario Gasparrini, Tom Glanzman, Elizabeth Hays, Heather Kelly, Chuck Patterson, Leon Rochester, Tracy Usher, Eric Winter

Travel Several who went to the Symposium took the opportunity to visit various other cities as tourist, sometimes combined with business. Richard and Tony Johnson went to DESY Zeuthen in Berlin, then to the CTA consortium meeting in Toulouse, to desribe Fermi computing and find out where CTA is in this regard (late, given that they are hoping to have the first telescopes on the ground in 2014).
ScienceTools: (Jim) Since last time Masa has tagged new versions of Pulsar Tools and Heather has added CLHEP namespaace qualifiers for CLHEP 2.1.0.1 to several packages.

See Science Tools Development Notes for details.

Burst advocate tools are accessible here. Jobs are submitted to lsf on the user's behalf. But there have been some problems, possibly connected with the fact that the jobs are run under the glastuser account. GRB folk can't current log in interactively under this account so can't debug. Probably there should be a separate group account for this purpose.
FSSC: (Eric W.) All quiet.
P6V11: (Tom G.) Tomorrow (25 May 2011) will be a new FT1 data release using P6_V11 IRFs. This involves Level 1, reprocessing, FSSC servers and the astroserver all coordinating with each other to make this happen smoothly. The transition is expected to take about one shift to complete.
Documentation: (Chuck) sends the following:

I hope to finish the pointlike tutorial by c.o.b. today, then create a new tag and ask Berrie to update the mirror site. Other than that, it's business as usual.
Pass8: (Tracy) A new GR tag is on the horizon; maybe will be ready next week. The big ticket item in this release is the upgrade to new G4: 9.4.p01. We're hoping to make datasets using this tag soon enough that people will have a chance to look at them before the Santa Cruz meeting. The reconstruction work for Pass8 is approaching "done" (more tweaks to be expected, however); the next big phase is event-level analysis. See Bill's C & A talk, especially slide 3 for schedule.
G4 and CLHEP Upgrades: (Heather) All GR packages needing mods (a lot) now have them. Several ST packages were also modified for CLHEP. pointlike and skymaps may still need some attention; Heather will take a peek.
Core talk:
- GR/Onboard filter: (Heather, Joanne) As noted last month, Tracy has been able to build and run against the new version of flight software. At that time the Linux distribution was missing CDM's: special data-like shareables used for configuration. Jana recently indicated where these can be found so testing on Linux should now be possible.
- Python (Heather) Python 2.7.1 is built and available in the GLAST_EXT area for redhat4 32-bit, redhat5 32-bit and redhat5 64-bit. Please try it out and let Heather know how it goes. Her promise to provide SnowLeopard and Windows builds is still in force.
- ft2util_2 (Heather) This proposed replacement for ft2util is nearly ready for production. Comparisons with the old code are in progress and look good so far. A code review is being arranged; could be when Heather is at SLAC in late June; could be somewhat earlier. (Jim [designated reviewer]) is willing to participate but would like to settle on a definite date. [Anders prefers ASAP.]
- glast-win04 (Heather) There was another disappeared known hosts file hiccup, since dealt with. Otherwise, things are going well on glast-win04. Tom now has all SCons Windows builds runnning there, accessing externals and nearly everything else locally and it's working very well indeed: processing steps have sped up by gratifying factors (somewhat different depending on which step). Kim has added glast-win04 to the pool of machines used for Windows builds, but externals are still accessed from the V disk so improvement is modest.
- GRBAnalysis disposition (Joanne) Latest plan is to follow Jim's suggestion: make a xxx-scons package consisting of GRBAnalyis and all ST packages needed to build the BackgroundEstimator shareable, but build static libraries for those packages so there is no chance of conflict of shareable versions at run time. Some of these packages (e.g. astro) will need a slightly-altered SConscript and possibly separate tags, which adds complexity, but better there than at run time [though maybe separate tags won't be necessary; stay tuned].
Announcements
- SCons meeting Tomorrow (Wednesday), 10:30 AM PDT
