Site status

CSCS

• Xxx
• Accounting numbers (from scheduler) from last month

PSI

• Upgraded my 2 HP CentOS7 NFSv4 NAS to ZoL v0.6.5.7
  • 1st is the primary NAS featuring 24 SAS disks 15k 600GB
  • 2ns is the secondary NAS featuring 12 SATA disks 7.2k 3000GB ( cold backup )
  • both owns a dual 10Gb/s card put in LACP bonding mode
  • on the secondary NAS I'm going to make a ZFS fs for dCache and provide ~5TB to the PSI T3 ; it's a shame to use this HW only for backups ( 5y warranty )

• Accounting numbers (from scheduler) from last month

UNIBE-ID

• Mostly smooth operation
• Procurement:
  • 80 new server (76*20 + 4*16 => 1584 new cores; disontinued 144 cores (oldest nodes)
    • installed and provisioned
• Migration from OGSGE => Slurm planned for Q4
• Probs with NAMD jobs (using ibverbs directly) => low level IB errors from mlx4 regarding qp
  • no errors with MPI jobs using ompi or the like
  • no errors with storage (GPFS over RDMA)
• ATLAS specific: large number of random a-rex crashes within the last 2 weeks
  • reason unknown, happened 24x between 2016-06-15 and last monday; no crash since 3 days

UNIGE

• Operations
  • 10 machines added into the batch system (80 cores) + 3 machines replaced:
  • DELL - Intel Xeon @ 2.4 GHz - with 8 cores and 48 GB of memory
  • RAID controller: Common problem for our DPM and NFS File servers (It happened like 3/4 times during last months)
  • Increased activity from DPNC users to run in the batch system (other groups, in addition to ATLAS)
  • Still not in ATLAS production, problems related with memory (hints provided by Gianfranco)
• Data Management: user datasets from UniGe for ATLASLOCALGROUPDISK at CSCS deleted (space can be moved to ATLASSCRATCHDISK)
• Accounting numbers (from scheduler) from last month
