Highlights:

  • Added latest EMI-3 version of StoRM to baseline version list, in addition to EMI-2. EMI-3 will be needed for FTS3 compatibility.
  • Known issues in BDII_top reported last week were fixed. Requires deployment of latest BDII_core on top-level BDII.

Experiment operations review and plans

ALICE

ATLAS

Nothing to discuss here from our side

CMS

Not much to report

  • Suggested merging of various support units (SAM, Dashboard, monitoring) is fine with CMS

LHCb

  • GRID Middleware : we open a GGUS ticket (GGUS:94546) to have the grid middleware bindings for python 2.7. We would like to understand how we can open a GGUS ticket for GRID middleware without specifying a ROC or TPM to avoid the misunderstanding of the CERN people
  • MC simulation : the ONLINE farm at the pit is running 20k jobs for simulation since one week

Task Force reports

SL6

gLExec

SHA-2 migration

FTS-3

  • StoRM version 1.11.1 was released in EMI-3 fixing several known issues, including the problems reported with FTS3 transfers on StoRM. Feedback from sites upgrading to this version is welcome, tests can be organized if needed.

perfSONAR

  • Still waiting for v3.3 production release
  • At the OSG planning retreat for the next year the request to have OSG host the perfSONAR-PS dashboard for all of WLCG is being discussed. More news will follow.

Tracking Tools Evolution

Content was added to the twiki of the TrackTools TF. Please visit and comment. A recipe for savannah-to-jira migration steps, reviewed by the jira experts, is also included.

AOB

Action list

  1. Add perfSONAR to the baseline versions list as soon as the latest Release Candidate becomes production-ready.
  2. Build a list by experiment of the Tier-2's that need to upgrade dCache to 2.2
    • done for ATLAS: list updated on 17-05-2013
    • done for CMS: list updated on 03-05-2013, updated on 10-06-2013
    • not applicable to LHCb, nor to ALICE
    • Maarten: EGI and OSG will track sites that need to upgrade away from unsupported releases.
  3. Inform sites that they need to install the latest Frontier/squid RPM by May at the latest ( done for CMS and ATLAS, status monitored)
  4. Maarten will look into SHA-2 testing by the experiments when experts can obtain VOMS proxies for their VO.
  5. Tracking tools TF members who own savannah projects to list them and submit them to the savannah and jira developers if they wish to migrate them to jira. AndreaV and MariaD to report on their experience from the migration of their own savannah trackers.
  6. CMS to appoint a contact point for Savannah:131565 and dependent dev. items for the savannah-ggus bridge replacement by a GGUS-only solution tailored to CMS ops needs.
  7. Investigate how to separate Disk and Tape services in GOCDB
  8. Agree with IT-PES on a clear timeline to migrate OPS and the LHC VOs from VOMRS to VOMS-Admin
  9. For the experiments to give feedback on the machine/job information specifications
  10. Experiments interested in using WebDAV should contact ATLAS to organise a common discussion
  11. Create a twiki for the FTS-3 task force
  12. Give feedback to the IT-SDC proposal to unify WLCG monitoring support in GGUS
