Swiss WLCG Operations Meeting on 2012-06-14
Agenda
Status
- CSCS (reports Pablo):
- GPFS issue / last maintenance. Changes performed: SM changed to normal host, firmware upgrades on all Sun cards, general kernel/ofed upgrades, IB multicast flood fixed, two bad cables replaced.
- Thor issue (soft lockup-cpu stuck).
- Compute nodes ordered (6x4).
- CVMFS deployed
- PSI (reports Fabio):
- We're planning to migrate to Chimera before end of July. I'm preparing an SL6 64bit PostgreSQL 8.4 VM about that.
- For SGE Admins: queue configuration with WNs of unequal compute power. Fast WNs used before of the slow WNs.
- Rumors about SGE future in our HPC/Grid context https://forge.in2p3.fr/projects/gess/wiki
- UNIBE (reports Gianfranco):
- UNIGE (reports Szymon):
- Quiet operations, SG has two other projects now. Occasional problems:
- job stout and stderr not delivered by torque, found in /var/spool/torque/undelivered/
- one 3 TB disk dead out of 10*12=120, in six months since we have IBM machines in prod
- Upgrade news and plans:
- ATLAS skeptical on the HEP-SPEC 2006. Me too.
- offers from: IBM, DELL, Fujitsu:
IBM with AMD comes first, only worry is 64 cores/machine
DELL with Intel comes second, hame HEP SPEC but fewer cores
