Core Minutes 9/13/2011
Core Minutes 9/13/2011ScienceTools: (Jim) Made a bug fix to gtsrcmaps, which was sometimes producing negative values. The new Likelihood tag was immediately promoted and a new ST tag, 09-25-01, created since the bug was interfering with analysis of some extended sources.
At Jeremy's request he has added a gtexpcube2 application.
See Science Tools Development Notes for more information.
FSSC: (Tom S.) No news.
Documentation: (Heather) n the interest of easing the maintenance of our ground software home and workbook pages, thanks to Tony, a new area has been made available and is automatically populated from our CVS version of the workbook via Hudson (similar to the RM). There are now new web addresses for both the workbook and SAS home pages. The old sites are still in place but will no longer be receiving updates. Redirects have been created to move your browsers to the new sites when you visit the old sites.
The new SAS Home is:
http://www.slac.stanford.edu/exp/glast/wb/prod/sas_Home.htm
The User Workbook is now located at
http://www.slac.stanford.edu/exp/glast/wb/prod/
Please update your bookmarks and note that you may have to refresh to get the redirect on the old pages to come up in your browser. If you experience any troubles or have questions, please send them along.
For those that update the workbook, you will continue to update the copy in CVS. When you do so, Hudson, will automatically create a test build which takes the HEAD of the workbook and posts it
Once there is a set of updates we desire to post "live", we will manually run a script to post the current test version to the production version of the website. If you have updates to the workbook that need to be posted to the production version of the website, please contact Joanne, Jim, or Heather.
Pass7 reprocessing: (Tom G., Richard) The most pressing issue if we move substantial parts of the processing to Lyon will be i/o. For timely return of all results we would need 5 or 6 times the bandwidth actually available. However we could defer the delivery of some data products in order to return FT1 quickly. (Tom) points out that, although bandwidth is a big issue, it is not the only one. There is more to do concerning distribution and coordination of software.
For a more complete picture of the project, including plans, meeting minutes, etc. see the Confluence page Tom created.
(Leon) has been looking in detail at an event found in Pass6 reprocessing but not in Pass7. He copied it over to Windows, where it is easier for him to see what's going on, but there Gleam crashes: perhaps because tracker clusters are mangled. The problem seems to be associated with writing it out and reading it back in.
(Leon) We're nearly ready for the calibration test: a comparison of runs made with old calibrations versus the same runs made with new.
GR/Pass8 (Tracy) There is a new GR release for which the default physics choice is QGSP_BERT_EPAX. There is more activity in the Tracker, especially at high energies. (Heather) Actually it hasn't been released yet. It's in HEAD, but she was thinking of confirming with Alex to make sure Cal code is where he wants it. There is some new stuff to associate Cal clusters with ACD.
(Leon) As soon as he has a chance, he'll get back to a project to improve the code which estimates energy from multiple scattering. He hopes to both improve it and to enlarge its range of applicability from the current limit of about 1 GeV up to several GeV.
Core talk:
rhel5 externals (Joanne) has an obf external for B3-0-0 against which test_OnboardFilter runs successfully. Have not yet tried it with test_Gleam. It wasn't built — it's made by copying various libraries and includes from flight and making some modifications in OnboardFilter. It also involves additions to SConsFiles for the new external and a slightly different way of handling it. For the most part the OnboardFilter changes consist of removing various #ifdef SCons segments from the code. The organization for B3-0-0 SCons is much closer to what is done for CMT. In order to make the code backward-compatible for B1-1-3, we'll need a reorganized version of that as well. This exists in development but hasn't yet been tried. flight has binaries of B3-0-0 for all supported Redhat platforms so it will be straightforward to copy a subset to make our obf external for rhel5. The subset we need is somewhat larger and messier than originally hoped, but that is a minor drawback.
(Heather) was able to build G4 on rhel5. We still need rhel5 builds of at least OmniOrb (not expected to be a problem) and Gaudi.
SCons RM (Tom S.) Windows SCons builds have been running all right since the last time he regenerated the configuration settings. He still plans to look into writing the settings to a file rather than to the registry.
Email notifications for snowleopard have been turned on.
(Heather) There is a mysterious problem with test_GRBtemplate, showing up only in optimized builds: test_GRBtemplate.exe fails to run, complaining about permissions, even though the permissions on the file appear to be set correctly.
Virtual machines (Richard) We might have a visit from some FermiLab folks reported to be VM experts. Could be very useful for us.
