CSCS

  • Systems:
    - Prepared all Phoenix servers to be shipped out to Gianfranco and Roland
    - Installed VM for ARC 6.x tests
    - Deployed CentOS 7 Image on Piz Daint

    - and re-deployed with the missing unzip package

    - Atlas is running on CentOS 7 and also LHCb by mistake (but no one is complaining)

  • Storage

    Scratch
    -
    No interventions in the last month, stable operation

    dCache
    - Deployed new nodes
    - Using GPFS as backend
    - Completed data migration
    - (!) CMS pools are 100% full since 3 weeks, still waiting effective action plan from CMS central ops

network usage during dCache migration

PSI

UNIBE-LHEP

  • Stable, running unattended
  • Setting up ROCKS 7 framework, with CentOS 7 and Slurm 18.08.6, first nodes to be re-installed shortly.
  • With a bit of luck, we'll upgrade without downtime (but with a period of reduced caapacity)
  • Monthly summary: Pledged: 42k, delivered 23.6k (22k last month)
  • Ubelix contributing ~46% (23% typical)
  • Running an average >2.2k slots (2.5k typical during the previous pledge period)

UNIBE-ID

  • ARC CE is running smoothly
  • Increased slot usage limit for ATLAS jobs from 600 to 1200
    • after having observed that the limit of 600 slots is not per partition but global
    • more increase possible, e.g all => 600, atlas-preempt => 1200 to make better use of idle resources
    • but often only few jobs got sent to atlas-preempt partition though a lot of resources would had been free (weekends)
    • tbd with Gianfranco

UNIGE

  • No news about the ARC re-deployment
  • Considering the proposal of closing the site in GOCDB

NGI_CH

  • Certificates
    • Obtained two certificates from QuoVadis to check:
      • One personal
      • One Server (ARC CE)
    • Was able to perform basic operations with them: validated
    • Next steps:
      • Sign a contract (this week?)
      • Trust/Link setup with admin rights to us
      • Fine-tuning the templates
      • ???
      • Operations

  • Yearly review of GOCDB information
