ATLAS SCCS Planning 07Feb2007
-----------------------------
9am, SCCS Conf Rm A, to call in +1 510 665 5437, press 1, 3935#
Present: Stephen, Richard, Wei, Chuck, JohnB, Charlie, Randy, Booker
Agenda:
1. DQ2 Status/Web Proxy
Has been running fine.
Have been transferring user data for Tau group work to SLAC. Did
need to restart DQ2 to notice that the data was at BNL instead of
just on the LCG.
2. Tier-2 Hardware
Have the list of hardware we want. Waiting for Sun to give us their
best offer on it. A week ago were told by Sun to suggest what we
were expecting. Gave them this aver the weekend and hope to hear
from them soon.
Note from Persis that as there is no budget cannot make
commitments.
The order has been held up waiting for it to match with other SLAC
purchases. There is the Tier-2 Workshop in about a month, would
have been a good time to show something about the hardware being
used.
BaBar usage hasn't been 100% so we have been able to use some batch
capacity for ATLAS.
Believe that John knows where to put it and power it. Everyone is
being told that things will need to be moved around later in the
year, so expect interruptions.
3. HPSS/gsiftp/xrootd
We have a module to allow gsiftp to interact with xrootd. It
functions well but we've uncovered several other problems with
xrootd, don't believe these are show stoppers or hard
problems. Some of them are small bugs. The behaviour is slightly
twisted. Need to talk to Andy, may not be able to do that till he
comes back from CERN. Andy should be at SLAC on Friday then goes to
CERN for two weeks. Will probably do two weeks later and will be at
IN2P3 for a week in early March. He will be at INFN also. These
are groups who have had a formal request from the experiment.
We are at the point where we could setup an endpoint and start
using it but we don't have hardware. Hope to setup one machine
before the March meeting. The behaviour will be different in a
cluster environment and we will see these issues mentioned above in
that case.
Jim Shank and Torre Weanus will be at SLAC the 12th March. They are
interested in having ATLAS work better and Jacek told them about
PetaCache. Should think about how we make their visit as productive
as it can be. Not sure a demonstration would be useful but having
things working would be good, should have some Tier-2 hardware
online by that time.
4. AOB
None.
Action Items:
-------------
061108 Richard Discuss with SLAC Security longterm approach to ATLAS VO
061115 No information.
061213 Nothing happened yet.
070103 No information.
070110 Richard & BobC in Denver, Stephen will email them.
070124 Don't know the status.
070131 Don't believe this happened.
070207 Have not done this. Randy has talked to Heather, didn't
have any time to comment today but she is aware about
it. Will treat each VO as an enclave, if you are using
anonymous accounts need to be able to show how ran a job
and when. The main issue is that VOs are not legal
entities and anyone can declare themselves a VO. Would
need to actually test that the required information can
actually be found.
