ATLAS SCCS Planning 01Aug2007
-----------------------------
9am, SCCS Conf Rm A, to call in +1 510 665 5437, press 1, 3935#
Present: Stephen, Wei, Richard, JohnB, Booker
Agenda:
1. DQ2 Status/Web Proxy
Nothing to talk about. Alexei is resuming the AOD replication to
sites. We have 350 to 400 jobs to run in the last days, so not a
big impact. Currently he is replicating 30%, should we increase it?
Not right now as there is an issue with the new DQ2 in that the PFN
might not match the LFN (if it can't write to the same name it adds
some more characters to the PFN) and the cleanup tool assumed this
was true.
2. Tier-2 Hardware
Tried to test eval01 earlier today but needed to be added to list
of users. Booker has done this. Now have a silly problem with ATLAS
software which will need to solve to do the tests.
Some email exchange on the list about 8 core machines. Will be
buying real soon now for BaBar to replace the noma and tories
(probably weeks). Torn between wanting to buy the exact same for
ATLAS Tier-2, but will not get the money till October/November so
it will be five months later so would not get the exactly the
same. Wouldn't want to do a competitive bid just for 40 machines,
could bundle it up or use a bulk purchase agreement. BaBar is also
buying storage, so that could be part of one larger purchase.
Would like to understand when it is optimal to buy the new Tier-2
hardware. Wei feels storage is urgent but CPU less so.
3. AOB
- Physics Workshop later this month
Post from Charlie on the mailing list. Request for no outages
during those four days (20th-23rd August).
- Security
Bob Cowles is a little worried about some solutions being
developed for US-ATLAS from a security point of view. One of the
items is to run "network performance toolkit" which has
particular issues.
At an OSG meeting they showed an OSG organisation chart and Wei
raised a question if the security part was consulted for the
deployment of new software on the ITB. Didn't really get an
answer.
Expect this will come up again. Would be nice if people thought
about security while developing and integrating software.
Have not installed GLEXEC yet on OSG. This will be used to
change userids for running jobs.
"Ask not what OSG can do for you, ask what you can do for OSG."
Action Items:
-------------
070801 Stephen See when new Tier-2 hardware is needed
070725 Stephen Try to test eval01
070801 Didn't have access when attempted, Booked fixed that.
Problem with ATLAS software (hopefully trivial).
070711 Stephen Find out about benchmarks for CPUs for next purchase
070718 Not done yet.
070801 Extracted data from our Production Database, need to
analyse it still.
