• Budget and PPA status
  • there is an ongoing review of the computing in HEP. Timeline: a report should be ready in December.
    The charge is to assess what is going on in the field and where the money is going.
    The 10% (people+hardware: 75M$) of HEP budget goes into computing resources.
    Solutions need to be found in order reduce the amount of funds that go into HEP computing.
    • Are common projects an option in our Collaborations based world? 
• SLAC networking to NERSC (Tony)
  • Very close to hit the ceiling in the 10GBit between SLAC and NERSC.
    A dedicated NERSC network connection from SLAC?
    Need to make a proposal.
• LSF and MPI .(see the progress report and meeting notes)
  • Better aggregation of single slot jobs on the same hosts, Is it ok for jobs with high I/O rates ?
    Also a wall time limit will be enforced. What about the CPUF ?
• Conferences

  • CHEP 2013 + DPHEP
    • Virtualization + C++ 11 standard
    • DPHEP common projects
• From previous meeting
  
  • Status of hardware purchases (PPA-ATLAS-Theory , Fermi)
    • PPA part will be indefinitely suspended, ATLAS money is use or lose, Theory group will go on with their part of the purchase as well.
      The infiniband and other infrastructure are missing at this point (it was in the PPA part). So the acquisition plan needs to be reviewed.
  • Policy Task Force
    • no update - it will involve mainly desktop systems, no scientific computing or data acquisition systems will be touched (not directly at least...).
    • 1.6M$ ...
  • SRCF update
    • not much here ...
  • Migration from RHEL5 to RHEL6
    • No more RHEL5 support at SLAC past Dec. 31st 2013.
      BaBar requested to retain a single RHEL5 build machine in the build queue.
