11:00 → 11:20 Experiment problems/issues

Review of weekly issues by experiment/VO - LHCb - CMS - ATLAS Production priorities: There is now a weekly (internal) Tier-1 Strategy meeting. I am to report any priorities/issues to this meeting. The focus is say 8 weeks ahead, but I can also raise more immediate problems. We should discuss the sorts of items that might be mentioned. - Other

11:20 → 11:35 ROC update

Ops meeting *************** ROC issues noted: CEs at CERN-PROD were under heavy load and generated many alarms for the COD. However, the CEs are behaving as expected because they disappear from the information system when they are overloaded in order not to receive more jobs. The monitoring tools should be able to detect this condition doing the appropriate correlation between SAM and gstat results. - 64-bit natively compiled WNs are in PPS. PPS team are looking for sites and VOs to test 64-bit in this environment. So far only LHCb has come forward. - Glite 3.1.0 PPS Update 19 passed the pre-deployment testing and it is now being deployed in PPS * WN 3.1 for sl4 64bits * glite-LSF_utils * lcg-vomscerts-4.8.0 adds next cert for biomed + egeode * new version of lcg-ManageVOTag fixing bug #31848 Release notes in: https://twiki.cern.ch/twiki/bin/view/EGEE/PPSReleaseNotes_310_PPS_Update19 - gLite3.1 Update16 to production in preparation The update will contain: * A new index to speed the BDII up * UI: Bug fixes to JDl API (bulk submission) and gfal cliens * dcache SE: Glue 1.3 clean ups * DPM SE: version 1.6.7 (32-bit and 64-bit) fixing various configuration bugs; introducing new front-ends for Xroot and HTTP/HTTPS; upgrading the version of gSOAP form 2.6.2 -> 2.7.6b * lcgCE: bug fixing - HS still blocked at these sites. What are the site intentions? * ce00.hep.ph.ic.ac.uk * ce01.tier2.hep.manchester.ac.uk * ce02.esc.qmul.ac.uk * ce02.tier2.hep.manchester.ac.uk * dgc-grid-40.brunel.ac.uk * dgc-grid-44.brunel.ac.uk * grid002.jet.efda.org * gw-2.ccc.ucl.ac.uk * helmsley.dur.scotgrid.ac.uk * mars-ce2.mars.lesc.doc.ic.ac.uk * serv03.hep.phy.cam.ac.uk * svr016.gla.scotgrid.ac.uk * t2ce02.physics.ox.ac.uk * t2ce03.physics.ox.ac.uk - DPM (FD): It has been proven that the ext3 filesystem is far less performing then the xfs filesystem for file deletion operations. In particular, deleting 2048 files with 1.5GB size takes 5 seconds on XFS and 90 minutes on ext3. Therefore, I (FD) think we should recommend that sites running DPM migrate from ext3 to xfs, if possible. In fact, running XFS does not have any counter effect, only benefits.

11:55 → 12:05 Actions review

12:05 → 12:10 AOB

- Blogs! The T1 is now publishing ... but the T2s should continue too! The alternative is the heavier T2 coordinator reports and I document updates to the blog. - Issues to raise at tomorrow's GDB: http://indico.cern.ch/conferenceDisplay.py?confId=20227. Note also the pre-GDB (today) on CCRC: http://indico.cern.ch/conferenceDisplay.py?confId=29170 (aside: Markus talks about CREAM and SL4 WMS timescales).
