ATLAS SCCS Planning 11Jul2007
-----------------------------

  9am, SCCS Conf Rm A, to call in +1 510 665 5437, press 1, 3935#

Present: Richard, Booker, JohnB, Randy, Charlie, Stephen, Wei

Agenda:

1. DQ2 Status/Web Proxy

    Was the 0.3 upgrade for DQ2. The central server had a problem so it
    is down till tomorrow. There has constantly been problems since the
    upgrade. Have not been getting many production jobs due to that,
    yesterday changed the batch system fairshare configuration so that
    the whole ATLAS priority can be shared between users and
    production.

    This was a big bang upgrade, not very well planned. Hopefully next
    time will do better.

2. Tier-2 Hardware

    Current purchase is all running.

    Need to start looking at next round. Assuming we get more
    money... as they do want more hardware online by the end of the
    year. It will be in the next fiscal year but it needs to be at the
    start of it to be able to get the hardware here and online by end
    of calender year.

    There will be infrastructure issues. There are many ways to
    approach these needs. Will be taking delivery of a Sun Black Box on
    Saturday. In a month or so it will be powered up. Only half of it
    will be used by BaBar needs. Could discontinue use of nomas and
    toris and put the power in that other half of the Black Box, could
    then put in water cooled racks for ATLAS purchase. However, in the
    past have taxed BaBar to provide general computing to the lab,
    perhaps it is time to pay that back by using other users' money to
    fill it. Either looks okay for ATLAS as the whole general queue
    will go up. Would need to wait for Black Box number 2 to provide
    full ATLAS capacity in next round to avoid piece meal installation
    around building 50. Would mean working as a target date for end of
    the year rather than a guaranteed availability date. For the next
    round the CPU purchase should be half and storage doubled, so
    might not occupy the same space. Density will be higher, which will
    impose some limitations on where it can be installed.

    The quotes for CPUs will be a competitive one so it will probably take
    around four months to do the acquisition. Would be good to get a
    volunteer to benchmark new machines.

3 AOB

   - BNL Storage

     Moving away from storing data on nodes towards Thumpers as the
     storage element.

    - Tier-2 Meeting

      Asked if we should invert the Disk:CPU ratio in purchase again,
      reaction was no, we should buy 2:1 Storage:CPU next time.

      Easier to reallocate CPUs to other users when it isn't in use. Is
      possible for storage but much harder.

    - SLAC Tier-2 Meeting

      Looks like last week of November. Using conference Room C&D. We
      should invite Tier-3 people as Tiers 1&2 will not provide
      enough. Will email Jim & Michael to see which days in particular
      and how many. Will be after Thanksgiving. Probably won't use
      InfoMedia as it is a small enough meeting. Will discuss budget
      with Teri.
