  • The node lcg-bdii.gsi.de has been removed from GOC DB since August 6th and is still tested by SAM: this is not correct, the node is still registered in GOCDB but has been removed from BDII; the COD will contact the site and follow up.

PPS Reports

EGEE Items From ROC Reports

  • Jeremy, UKI: while investigating some inefficient biomed jobs, we have seen biomed jobs mapped to dteam, site configuration problem? accounting problem?
  • Jeremy, UKI: multi-threaded jobs, run more often by biomed, which affect the performance of other jobs in the same nodes

gLite Release News

  • Soon in production: gLite3.1 Update28 in preparation. This update has been delayed due to issues with the release process but will be released within the next days.

ATLAS Service

The Atlas specific SAM test are now run successfully in the NDGF T1

ALICE Service

CMS Service

  • CMS has finished 3 of of 4 mid-week Global Run exercises, as planned. They are 1,5 days long exercises. From the computing standpoint, it has been a valuable set of exercise to check the full T0 workflow, also on (relatively) recently deployed components, from P5 down to transfers of the data to T1 sites, with custodiality also. We plan to run a CRUZET-4 cosmic run exercise in the time slot August, 18th-25th, most probably continuing after that with magnetic field on. From the computing standpoint, and from the support and shifting experience, we are trying to use these exercises to get prepared to a season of constant data flow.
  • Problems found: some network at P5 issues, some DB-related interventions and issues, all properly documented and discussed with CERN-IT in several fora already. Progress can be done on identified areas, work is being done especially in the communication flows, and CRUZET-4 will be a chance to test for several days in a raw a quasi-real-life scenario for cosmic data flow and in general for some computing workflows.
  • NOTE: agreement with Castor@CERN for upgrading the CMS instance of Castor@CERN to 2.1.7-14 version was found for tomorrow, Tuesday, August 12th, 09h00-11h30 CERN time.

LHCb Service

not present

OSG Items

  • GGUS:37948: the ticket is fixed (in the OSG side) but it remains in state assigned
  • GGUS:37059: fixed
  • GGUS:39303: just updated, it is in progress
  • GGUS:39445: verified, what do we need to do? nothing, it means that the user has verified the solution and it can be closed; seems that some cern-remedy info did not make into the ticket, to be investigated
  • GGUS:39481: interesting cut and paste, no idea on what it means; it looks as if part of the text was cut, and it has a cern id, similar to the previous case.
[Steve T]: we meant to reassign these tickets to OSG and close them for CERN ROC; instead, they were set to fixed. Both need to be followed up. Steve will do that. Rob will be at CERN at the end of the month, it would be good to meet and discuss these issues by then.

Review of Open Action Items

(see the action list)


  • Jeremy: what is the aim of the Gridmap tool? sites, grid operations, technical people, not managers as information there can be misinterpreted; many degraded CEs in many regions, the UKI plans to review/investigate the status.
  • Alessandro, Atlas: Atlas uses for their shifts special accounts with one single user and password shared by a shift group; is it possible to map these special accounts to GGUS? problems: these users don't have a certificate. This is added to the GGUS shopping list. Torsten: would it be for information only? A: no, we need a real user, a shifter might only do 1 week of shift and does not need to sign up in a list for 1 year. Torsten: could it be a mail account? A: yes. but we will need to also send tickets, normal, alarm and critical ones. Torsten: then it is more difficult. To be discussed.
