Core Minutes 5/3/2011

Present: Joanne Bogart, Anders Borgland, Toby Burnett, Jim Chiang, Warren Focke, Tom Glanzman, Heather Kelly, Chuck Patterson, Leon Rochester, Tracy Usher, Eric Winter

ScienceTools: (Jim) No development news. The ST development notes were updated to indicate that Heather had tagged containerSettings on April 15 so that new externals catalogProducts and diffuseModels will be accessible to code.

See Science Tools Development Notes for details.
FSSC: (Eric W.) He was able to port the latest tag to the new (showed up Thursday) version of Ubuntu with no problems.
Documentation: (Chuck) sends the following:

It's business as usual in WB world. I'm picking up the threads from where I left off in updating the Science Tools and updating other WB pages, links, etc. as I discover obsolescence problems. All of the WB's site maps are now pretty much obsolete and need to be updated. I also need to create another tag, so that the mirror site can be updated. You can follow the changes in the WB's change log linked in from the main "splash" page.
Pass8: (Tracy) Getting posters ready is the major activity. However, looking over Luca's poster, he (Tracy) realized there was a bug in the new pattern recognition affecting handling of certain kinds of events — now fixed.
G4 Upgrade: (Heather writes as follow) Francesco has committed updates to Event, G4Generator, G4HadronSim, GlastMS, IExternal/CLHEP, and IExternal/Geant4Runtime. All changes are at the HEAD and are not tagged. Francesco also supplied the Geant4 9.4.p01 build for RHEL4. What remains to be done is checking in the modifications for the CLHEP namespace to support CLHEP 2.1.01. Francesco will try to do that by the Fermi Symposium, otherwise Heather will attempt to make and tag the changes which would then be incorporated in a LATEST GR build. Heather asked the Pass8 folks whether we dare promote these tags. Tracy responded it is still necessary to validate the new G4, but that inserting the upgrade into a tagged GR will likely fuel that effort.
Gaudi Upgrade: (Heather writes as follows) Heather has a local copy of the GlastReleasev18r8p14 branch on RHEL4 with the Gaudi v21r7 upgrade. Work is being done to be sure it compiles with CMT and SCons on both RHEL4-32 and Visual Studio 2003. Once that is complete, Heather intends to commit the branch and see about merging the changes into the HEAD of GR (with the ok from the Pass8 folks).
Core talk:
- CMT RM (Heather) ..had filled up the V drive. The only way to clean it up currently is to go in and delete old builds by hand, so she did that. We should now have enough free space to last a while. Is anyone running against those builds? [No interest expressed.] We can consider deleting them more regularly and promptly, e.g., after a week if the only people using them are those doing post-mortems on failures. (Joanne) would like to keep at least config.log and possibly other files of diagnostic interest.
- MySQL upgrade (Joanne) Apparently the glastDB alias will not be available indefinitely, but it can be kept around for some period after the move, which is good enough to smooth things over for the calib db.
  
  See this Confluence page for a list of affected databases.
- Tagging (Joanne) traced the orbitSim RM build problem to an incomplete tag: files in the orbitSim/src directory were lacking various ScienceTools-HEAD... tags, hence would not be checked out by RM when those HEADs were built. Because of the way the tagCollector script works, one incomplete HEAD tag will engender future incomplete HEAD and release tags until someone fixes the most recent HEAD (now done). Clearly this system needs an overhaul! If this subject concerns you, see analysis and proposals and come to the SCons meeting on Wednesday.
Announcements
- SCons meeting Tomorrow (Wednesday), 10:30 AM PDT, featuring MySQL migration and tagging discusions.
- Power outage reminder (Tom G. sends the following) The second of two planned power outages will take place at Building 50 from 7 a.m. this Saturday until about 6 p.m. Sunday as the refurbished Substation 8 is brought online. However, servers will begin to be powered down Friday evening.
  
  There's a blurb about it in SLAC Today [as well as an article about Fermi and the Sun].
  Tony J has a Confluence page listing the Fermi resources, and identifies those that should be kept up during an outage. So this will affect the RMs - as I recall we don't have to shut down anything - but rather the jobs will just hang until things come back up.
- Welcome to this world, Kayden Jeffrey Stephens!
  
  From Tom S.:
  
  [He] was born at 4:20 pm Saturday evening. He weighed in at 7 lbs 8.3 oz and was 20.5 in long. Mother and son are doing fine.
