Agenda

• Status
  • CSCS:
    • new record on CPU normalized hours
    • small problem with new NGI-CH nagios monitoring
  • PSI:
    • New person (Fabio)
    • Thinking about High Availability using vmware features.
    • Want to concentrate in improving Puppet configuration.
  • UNIBE:
    • added 320 cores to cluster (now 456 job slots, very efficiently used by ATLAS jobs from NDGF over ARC)
    • started run ATLAS analysis, folded in the ANALY_ARC queue from the NDGF cloud. Smooth integration
    • no time to make progress on DPM storage, hope to have it online within the next 7-10 days
    • now also support "Life" VO within the SMSCG infrastructure. Will support more SMSCG VOs and aplications in the near future
  • UNIGE:
    • one recent crash of a file server running Solaris; we have a few such crashes per year; probability below 1/machine/year; all our file servers (eight Sun X4500+ aka "Thumpers", 4 do NFS export, 4 are in DPM) are concerned
    • data tranfers from NDGF-T1 to Genava at 30 MB/s; we would like 60 MB/s (~1/2 of the line speed to SWITCH backbone); investigation in progress, involves SWITCH and Ljubliana, iperf measuremeents between IJS and Uni GE show wild oscillations of the rate; will be followed up
• Next CSCS maintenance
  • Network cut, dCache upgrade, filesystem checks.
