ATLAS SCCS Planning 04Apr2006
-----------------------------
Present: Len, Stephen, Wei, Charlie, Gary
Agenda:
1. DQ2 Status
Publishing a dataset fails due to web server certificate. However,
retrieving data does work.
2. mysql replica Status
Dieter has reported there are now versions of the ATLAS production
wrappers that will use the local replica. No update on the hardware
request yet.
3. Trigger Farm Status
No discussion.
4. ATLAS Batch Commitment
For the short term it is whatever we can scrounge. We would like to
flood the OSG queue with test jobs. If there are free resources we
could ask for it to run on more machines. May need to change OSG queue
parameters in the future.
Assuming we win the Tier-2 proposal, that is when we need to guarantee
those resources to ATLAS. The decision will not be till after the July
ATLAS collaboration meeting. Probably no money till next FY.
5. AOB
Question from ATLAS production on http access to CERN and BNL. It was
agreed that it should be possible to use a web proxy. This is used to
define the job parameters. Told that a job will die if it cannot get
these parameters.
Stephen will setup a web proxy. Will only allow connections from on
site to CERN or BNL.
May take a while to converge as need the production shifter to submit
the job. The shifter works 9-5 in their own time zone.
Action Items:
-------------
060405 Stephen Setup web proxy
060308 Stephen Determine source of SPECint2k numbers for other sites
060315 Not done.
060405 Not done yet.
060308 Charlie Think about commitment to ATLAS pre-Tier2
060315 Not done.
060405 Done.
060308 Stephen Check with ATLAS if there is an update mechanism
060315 No mechanism yet except for reinstall. Could ask some BaBar
folk about how we do this to see if it is applicable.
060405 No update.
060224 Stephen Enquire with ATLAS about certificates for DQ2 machine
060301 Not heard back from ATLAS folk, Wei pointed out a DoE
place to get service certificates.
060308 No update.
060315 No update.
060405 No update.
060224 Systems Provide DQ2 machine
060301 In the queue.
060308 Not done yet.
060315 Not done yet.
060405 No update.
060224 Systems Provide mysql replica
060301 In the queue.
060308 Not done yet.
060315 Not done yet.
060405 No update.
060224 Chuck Will check on web server request for DQ2 machine
060301 Waiting for web server request information from Stephen.
060308 Haven't checked yet; haven't received Stephen's request yet.
060315 Still not sent Chuck information.
060405 No update.
060224 Richard Discuss ATLAS trigger machines with others in SCCS
060301 Only limited response from John W was resigned
acceptance... need to work on an actual deployment plan as
there are real issues to be solved.
060308 John aware and in plans as much as anything is. New
engineer will take over.
060315 No update.
