ATLAS SCCS Planning 17Oct2007
-----------------------------

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

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

Agenda:

1. DQ2 Status/Web Proxy

    PANDA has been switch between DQ2 and PandaMover but things look
    okay at SLAC. There have been a lot of updates at BNL, the latest
    to DQ2 0.4.0 which seems to have make everything run well again.

    Need to work on getting a GSI authenticated PandaMover
    working. Were looking for a new machine but could perhaps use the
    existing machine as has was quite low CPU usage.

    In the future it is better to know the plans ahead of time to get
    security involved before software is deployed. Not sure there are
    existing communications channels that would allow this, may need to
    discuss with Michael or Torre.

2. Tier-2 Hardware

    Evaluating three candidates for BaBar, all Intel based. Will almost
    certainly want to get the same for ATLAS. For BaBar want to order
    mid-November and installed in December. To order together the
    money would need to arrive this week so unlikely. However, should
    be able to order more similar machines later.

    GLAST will probably be ordering on the same timescale as ATLAS so
    can put those together. GLAST want their machines by sometime
    mid-January, although their launch date has slipped a little.

    Almost certainly Intel quad core. AMD have had difficulties getting
    theirs out and it looks like GA would be first quarter of 08.

    Will be running RHEL4 on the new machines.

3. SSH w/ token passing

    With the switch v2 and Kerberos 5 you cannot pass CERN tokens to
    SLAC anymore. You could use things like getToken and setToken to
    pass it. You don't need to be root to use setToken, not sure about
    getToken. These are external commands (not standard AFS).

    Normal work method is to acquire tokens for SLAC and CERN on laptop
    then you can log on to both CERN and SLAC and use both cells.

    No one seems to be complaining though. Beyond the general issue CVS
    might be an issue. Booker/Wei will talk to DavidM to see if it all
    works okay.

    Will also try to think of other issues. Wonder if other labs also
    have an issue. Might be worth discussing at HEPiX.

4. Tier2/3 Workshop

    Wei forwarded an email about the agenda to everyone from
    MichaelE. RobG has setup a page at CERN with the agenda. The
    InfoMedia people have sent Wei a page for the meeting. It looks
    very nice and Wei has asked them to go ahead. There is an account
    to accept registration and payment. This needs to be added to the
    web page. They would also like to setup early registration before
    14th November. Need to make sure there is enough time for folk to
    register. Wei will forward the URL of the InfoMedia page.

5. AOB

    - Network Tuning

    Single transfer can get 700-800Mbits/s in each directory. The
    transfer buffer was changed and a hardware function was turned
    on. There are statistics from BNL to various Tier-2 sites, you can
    see SLAC jump from 150Mb/s to 800Mb/s there. 600Mb/s works out at
    5TB/day, we don't really have that much data to transfer. Right now
    there is a transfer test every two to three hours.

Action Items:
