11:00 → 11:20 Experiment problems/issues

Review of weekly issues by experiment/VO - LHCb - CMS From WLCG update: " * Job processing: CSA07 (GEN-SIM) pre-Production so far: 78.5M events(Minbias: 24M, PH soup: 45.9M events, DPG: 8.5M events), at a steady rate of ~47M events/month (w/o Minbias). CSA07 (GEN-SIM) left-overs: 37.6M events; i.e. assuming same production rate as so far, < 1 month to finish the total pre-CSA07 production. --- Castor@CERN issues seen during T0 tests are being addressed. * Data Transfers: "production" transfers continue: among 47GEN-SIM workflows, 28 are done but only 21 DIGI-RECO workflows ready due to data transfer tails to T1s: being debugged. --- "Test" transfers: the Debugging DataTranfers (DDT) program improved already the number of commissioned links to be given to Data Operations: from 11 (previous weekly report) to 35 (lastweek)." - ATLAS - Other

11:20 → 11:35 Ganga/DIRAC experiences

Feedback from Greig on using the LHCb tools - things we should improve on the deployment side

11:35 → 11:40 ROC update

- TPM https://gus.fzk.de/pages/tpm.php. Team 7: 13/08 and Team 8: 20/8 - COD https://cic.gridops.org/index.php?section=cod&page=homepage. Backup site 30/7. Lead site 3/09. Items from Ops meeting - Request from CERN PPS site to publish GStat test results to SAM. This will be enabled today. - # Germany-Switzerland ROC: DESY reported: After installation of gLite production upgrade 27 the user mapping on the dcache_SE changed when using the kpwd mechanism. The reason is the introduction of a new grid-mapfile-to-kpwd converter script in the RPM d-cache-lcg-6.2.0-1. Now sgm/prd users are mapped to sgm/prd accounts although they were previously mapped to the first VO poolaccount. Unfortunately we did not find anything in the release nodes. Other sites should be warned. # Germany-Switzerland ROC: DESY reported: Having installed SL4 WNs with gLite 3.1, we see that some rpms are missing. Unfortunately, these provide essential user utils like lcg-infosites. Is this planned by the Middleware group? Have they made an announcement? Are there plans to provide these RPMs for the gLite 3.1 version on the SL4 WNs? - SEE ROC will take gLite-CE out of production due to stability concerns

11:40 → 11:55 Revisit - killing jobs discussion! (Item from 17th July meeting)

- Taking forward proposals to the TCG. How should jobs be killed such that useful information is sent to users. - Results from other sites examining CPU/WALL time tails

11:55 → 12:00 AOB

- Stability of GridLoad tool - Grieg's observation re. failed SAM tests and use of ops groups - T2Cs - please get sites to check their SAM history http://www.gridpp.ac.uk/wiki/SAM_availability:_May-July_2007. Good to see many sites have already responded to the request last week.
