ATLAS SCCS Planning 06Sep2006
-----------------------------
9am, SCCS Conf Rm A, to call in +1 510 665 5437, press 1, 3935#
Present: Su Dong, Richard, Wei, Booker, Charley, Len, Chuck
Agenda:
1. DQ2 Status/Web Proxy
Nothing changed. I've done installation using atldq2 but fully
configured or active yet.
Don't believe we need to install FTS as we believe that the
instance at BNL will manage transfers for us.
2. Slots for ATLAS Production jobs and other batch related stuff
Atlas batch group 200 shares for local users in the general
queues. We monitor it to see how it works.
The CPU limit is too short for the ATLAS production jobs in the
general queue except for xxl (which has a limit of 8 jobs). Could
perhaps double the CPU time for the general queues to allow them to
get into xlong. Should also increase limit on the number of jobs
per user. Have now moved the ATLAS production jobs to the general
queues so need to update the batch system to fix these issues.
3. Validation of ATLAS jobs on RHEL
No news this week. Need to understand what would trigger a
validation. Perhaps shouldn't worry about the kernel?
4. AOB
- Pacman mirror at SLAC?
Could possibly do this. Need to worry a little about it become a
too big a load on the services. Need to find out how much load
this puts on other sites. Not certain why ATLAS needs so many
mirrors as OSG uses one web server for everything. Using FTP as a
file transfer mechanism would be more efficient but don't believe
that pacman supports that. Will decide after feedback from the
Tier-2/BNL meeting this morning.
- Oracle server
Current plan we don't need it.
- TDAQ Test Farm
30 machines have been installed. Probably do another 20 this
week. RonB said we could move them next week. Not in a big hurry
to get them out, so we can probably use them down there till they
move.
