Core Minutes 1/29/2008

Present:  Anders Borgland, Toby Burnett, Emmanuel Cephas, David Chamont, Jim Chiang, Seth Digel, Richard Dubois, Warren Focke, Tom Glanzman, Navid Golpayegani, Heather Kelly, Michael Kuss, David Landriu, Maria Monzani, Chuck Patterson, Igor Pavlin, Roberto Primavera, Leon Rochester, Tracy Usher, Eric Winter
 

• Big Run News: Ran into trouble over the weekend with a large number of failed opssim2 jobs.  Seth realized that there was a bug fix in celestialSources/eblAtten that may not have made it into GR.  Jim and Nicola confirmed, and in fact, the tag in use was a previously noted bad tag that had been mistakenly applied to the whole celestialSources container.  There is now GR v13r9p3 which includes the correct tags of eblAtten and GRBtemplate, as well as the latest CEL updates in RootIo and rootUtil.
  Richard noted that a number of machines in the farm are down til afternoon.  In any event, there are 5000 runs in the can.  Anders has looked at L1 processing needs and the files
  are there and will be checking they are functionally correct this afternoon
  
  Seth asked, "How long is each run in simulated time?"   2 seconds according to Tom
  
  Next up is getting GRB grid runs going with Interleave.
  We made background runs a couple of weeks ago.  Tom, Michael, and Emmanuel have been producing the booking xml files.
  Tom report that most of the bookkeeping is done - small tasks are left for Michael and Emmanuel including:
  • Renaming albedo event files to some naming convention and moving binned background files into xrootd
    ideally in the future, they will be built in place.
  • Copying the binned backgrounds (11 GB) to Lyon

  Lyon will be generating AllGamma runs.  10 mill events up to 365 GeV?? 59 million events up to 50 GeV.
  Richard had proposed not to put write recon trees so we will test reprocessing??
  
  Heather than discussed lessons learned from this latest GR issue.  Toby had proposed that we use the same set of celestialSources as defined in ST.  Perhaps when SCons is in production mode, we can pursue this further.
  
  While investigating the opssim2 issue, Heather found that valgrind 3.2.0 installed at SLAC reported an error that has since been fixed in valgrind.  Anders had build 3.3.0 to allow valgrind to be used, and a request was made to SLAC's unix-admins that this version be installed for general use.  Unfortunately due to lack of resources, this request cannot be fulfilled for some months.  Instead, we will install valgrind in the AFS area.
   

• ACD Review:  Part II is set for Thursday morning at 8 AM Pacific.
   
• CELs:  David has made some updates to RootIo and rootUtil that are now tagged and in GR v13r9p3.  This versions produces workable CEL files with the names of the trees and branches hard coded and appropriate for use in the skimmer.
  Richard asked Tracy: now we have working CELs in Gleam and Tracy is leaving town on 9th/10th of Feb.  What is the status to get Interleave to use CELs?  Tracy replied that he has downloaded and is building the new GR tag and is working to finish to integration process.
   
• Travel News:  Joanne is in Italy visiting her daughter in Milan today who is teaching English.  Joanne will be back in a week or so.
  
  Richard leaves Sunday, returns the following Saturday to attend a meeting in Bari.  He'll be sharing a flight with Leon, and with Julie out of Dulles.  Toby will be gone as well, and departs on Saturday and returns Friday morning.
   
• SCons:  Work continues to get all ST packages tagged using the new-style tagging.  15 packages are left, and Navid has started to manually tag those.  He is contacting the owners individually.  He hopes to have a ST LATEST build to allow others to experiment with SCons.  He does warn that packages may not compile immediately, as he notes there are some issues such as header files in the wrong locations.  E-mail alerts are now being generated for the new-style tags.  We plan to have a more extensive SCons discussion in about two weeks, when everyone has returned from travel and all of the new-style tags for ST should be in place, allowing testing.
   
• AOB
  Karen is working on the new RM web interface.  Comments are welcome.  Heather has high hopes for a new tag collector.  The page is probably not visible outside of SLAC unless running VPN:  http://glast-tomcat03:8080/releasemanager/releaseManager.jsp
  
  The issue with APE 2.3 on windows is solved by using CMT to define the Visual Studio solution to build the library.  A new CMT package has been passed on to James Peachey.  Jim Chiang wanted to know if the plan was to continue to have APE be an external library or to make it a ST package.  Heather replied that was really update to Jim and James.  In the meantime, we should just use the newly compiled library and update the windows version of the external.  That was done after the meeting.
