Core Minutes 9/14/2010
Core Minutes 9/14/2010ScienceTools: (Jim) is working on a problem with binned likelihood. He expects to have a fix in place later this week.
FSSC: (Eric W.) v9r17p0 was released last week. v9r18p3 has been imported.
Astroserver malaise: (Tom) The Astroserver grinds to a halt, or nearly, when given a large query. Small queries go through all right. Only Oracle experts are likely to be able to unravel this one. Ian MacGregor and Dan have been looking into it. One possible factor is the recent upgrade of the server from rhel4 to rhel5: some misconfiguration may have crept in.
skimmer: (Tom) For reprocessing it's used in merge mode. When one of the inputs isn't found, the job goes on its merry way, with no obvious indication that something was missing. David has a fix but has been unable to try it because his access to xroot was mistakenly removed (now resolved and code tested).
Core talk:
SCons RM (Tom) Snow Leopard builds are held up until sys admins can make an qppropriate batch queue. We also need a build of Qt for Snow Leopard.
He has tried to start up GR LATEST builds, but they've been failing early on: the cvs checkout fails, apparently with a timeout error. The timeout value is hard-coded in the RM, so in order to change it, RM needs to be rebuilt. This promised to be a daunting task since the Qt libraries on which RM depends had all been deleted a few weeks ago when the glastrm account was trashed. Fortunately, a backup copy was found so the rebuild can proceed.
(Heather) More generally, we should make sure everything of interest in the glastrm and glast accounts is backed up. Current versions of source should be in CVS. Binaries should be backed up to a safe and well-known place.
SCons build of ST on Windows (Heather) Toby's only hang-up currently is with tip. Other problems have either been fixed or he has been able to work around them. James Peachey had been called away but now might have some time to come up with a fix. He is willing for someone else to jump in if he can't get to it fast enough, but it's not at all clear who the "someone" would be.
SCons and GR (Joanne) The tags now in GR HEAD all build with SCons. test_Gleam and test_OnboardFilter run, but not properly because they can't find obf libraries. Some changes to code (in packages OnboardFilter, facilities and SConsFiles) and to the collection of obf libraries were sufficient to get test_OnboardFilter to run properly, but test_Gleam now crashes in a strange manner: OnboardFilter spawns a second thread intended to monitor data, but its stack appears to be corrupted and it crashes. We most likely don't need this monitoring thread for ground running — it's really intended for the flight environment — but our CMT builds do start it up and it's perfectly well-behaved. The most likely culprits would seem to be a (still?!) incorrect set of obf libraries, or some other build-related problem, but I'm running out of ideas. (Heather) Tracy, due back next week, may have some insight.
Gaudi (Heather) The new Gaudi has now been built for VS 2008 as well as VS 2003 and Linux rhel4; in fact the new build went remarkably smoothly. She is making another pass, exercising test programs and fixing problems as they are discovered. Currently she's working on an issue with test_Overlay. Remaining bits are:
