ATLAS SCCS Planning 16Aug2006
-----------------------------
SCCS Conf Rm A, to call in +1 510 665 5437, press 1, 3935#
Present: Booker, Stephen, Wei, Richard, Chuck, Randy, Charlie, Steffen
Agenda:
1. DQ2 Status/Web Proxy
Tried limit access to bear minimum. Difficult to find out what that
actually was. Stopped production at SLAC since Monday. Opened up a
little yesterday (to allow updates from inside the SLAC network).
Developers have had feedback about security from their
management. Two issues to do with it. There is the web page with
the username and passwords. And there is the issue of leaving that
user as being able to do anything with the mysql database.
No other feedback yet on the webserver. Pleased with the fact that
offsite use has been limited. Not sure if it still requires
permission or not (no offsite access but the administrator can
change it).
2. Trigger Farm Status
Nothing to say this week.
3. ATLAS Oracle Server
The machine is installed (racked and powered) and working with
Charley to get a network.
4. Slots for ATLAS Production jobs and other batch related stuff
Neal is back, so he can set it up now.
iptables hack has been deployed on the batch system. It looks like
the success rate recently has been near 100%. We could think about
increasing the number of jobs that can run for production. Not sure
we want to raise the limit while everyone is out of town, perhaps
after we get back next week.
5. Tier-2 Web Page
Wei has agreed to be responsible for the webpage. Richard has had
an exchange of email with Su Dong and Doug Olsen about what to do
with grid certificates. Folk should get a SLAC certificate, as
people at SLAC will know in general who they are. Arla would be the
sponsor.
There are some issues to do with adding users to the list of users
being able to use SLAC. It does seem that being added to the ATLAS
list doesn't actually entitle you to get access, so it is fine that
this is a different step. For the moment I (or Charlie) can email
requests for people to be added.
For normal accounts they should fill in the SLUO form and then fax
the account request form (and other AUP forms) to Charlie. Not sure
how we add new place to the list of institutions on the SLUO
form. We still need to establish who the PIs are. This is probably
an issue for SLUO. Perhaps should add all US Institutions.
6. AOB
Tier-2 Advisory Board meeting was help last Monday. There were Jim
Shank and everyone but Peter Long and Charlie from the proposal and
many folk from SCCS. Was appropriate not to have Richard as the
chair. Nominations are accepted up to Monday and then there will be
an election, some already received. Richard describes our plans to
get the Tier-2 up before we get any money. Would like to get it
fully functional by the time of the analysis workshop at LBL in
October. Talked about the relationship between the top down
management from ATLAS and the upwards representation from the
users. The Resource Allocation Board for US ATLAS happens to have a
person from each Tier-2 so perhaps should have the chair added. The
current situation is that 80% of the Tier-2 resources so go to
Simulation Production, that is a little strange as 2/3 of the money
was directed to go towards storage (which are not used a great deal
by simulation production). To keep resources flowing into Tier-2s
it is important to be responsive to local requests. It seems like
the ability of the Advisory Board to steer decisions will be
stronger than it might look on paper. As we have no experience of
running the Tier-2 wanted advice on if the split was okay in the
proposal between disk and CPU. The current setup was described where
we have SL machines for building and run RHEL for the backend. Jim
would really like us to make that work for ATLAS but someone has to
do the validation. Need to arrange for someone to do the
validation. Not sure what a validation is currently. Production
does do some sort of validation before running, so something has
already been done.

Action Items:
-------------
060816 Wei Setup ATLAS/SLAC Webpage
060816 Charlie Talk to SLUO about adding institutions.
060816 Neal Setup atlas priority group for LSF
060816 Chuck Check with Bob about web server approval need
060809 Richard Come back with person responsible for web site
060816 Done. Found Wei.
060809 Stephen Ask what dq2user needs to do in MySQL 060816 No good
answer. Limited to dq2user from offsite can only SELECT
from localreplicas. From onsite can do
SELECT,UPDATE,DELETE and INSERT to either localreplicas
or queued_transfers_SLAC. We'll see if that works or
not. Without onsite privileges production stopped.
060802 Stephen Find out about failing ATLAS jobs at SLAC
060809 Wei asked if anything useful and there were 9 completely
successful jobs (but those were tests). We should find
out if the intermediate files are kept and are useful.
060816 Wei iptables to use the local replica seems to solve the
problem. Done.
060726 Stephen Find out about maximum memory and local storage per job
060802 No news yet.
060809 No news yet.
060824 Official answer is 2GB memory... biggest is reco just now
at 1.3GB, still to add magnetic field map. Many simulation
jobs around 500MB. If we don't put more than one ATLAS
job on a node should be okay for the near future. Raises
question of how much pressure we feel to put on non-ATLAS
orders to get more than 1GB/core.
060412 Systems Provide Oracle service for ATLAS Trigger testing (RT
46089)
060419 No ticket yet, so nothing done.
060426 Now have ticket 46089.
060503 No news.
060524 Steffen has provided configuration information. Now in
Chuck's
hands.
060628 Randy will ask Chuck about status.
060726 First on list for V240 but not sure when it will
happen. Will put a T3a on it.
060802 John checking for rack space.
060809 Still needs allocated rack space.
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.
060412 No update.
060419 No update.
060426 Resubmitted request as it was lost before.
060503 Not heard anything for about two weeks.
060524 Stephen need to update ticket, moving from yakut to DQ2
machine.
060628 Request updated now running on atl-dq2, waiting for scan.
060726 Meeting on Monday about this.
060802 Requesting new user to run services, blocked offsite web
access, Need to explore MySQL security.
060809 New user available, more ideas for MySQL security.
060816 New action item created due to change of request.
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.
060405 No update.
060412 No update.
060419 No update.
060426 No update.
060503 No update.
060524 RT 45823. Engineer looking at power availability. On track
for
August.
060628 Understand schedule, Randy will make sure John is aware.
060726 Need to nail down when power will be available. Steffen
things he can make it happen with existing equipment.
060802 Looks like this will fit in SCCS. Can reuse rack,
switches and fibres.
060809 Everything looking good for this now.
