  1. Quarterly report SouthernTier-2 Quarter 03 2005 P.D. Gronbech

  2. Current site status data • Local network connectivity is that to the site SE • It is understood that SFT failures do not always result from site problems, but it is the best measure currently available. Results based on the old SFT page as this contains history, Site only deemed to have failed if it did not have a good set of results for a particular day. Quarterly report: SouthGrid

  3. All GridPP Resources * The Bristol Babar cluster transferred to Birmingham ** Delayed purchasing due to lack of computer room *** Delayed purchasing due to earlier lack of use • The GridPP-Tier-2 MoUs made reference to integrated CPU over the 3 years of GridPP2. Under the “Promised – integrated kSI2K hours until this quarter” an estimate is provided of what the Tier-2 would have expected to provide to this quarter on the basis of planned installations. “Static kSI2K” shows what would currently be expected if all purchases planned to this quarter had been made and implemented. The actual columns show what has been delivered. • RAL PPD delayed purchase due to lack of use earlier in year. Quarterly report: SouthGrid

  4. LCG resources * This figure includes the older se also, not currently reported on the gstat pages. ** 50% of ATLAS Farm available to LCG. *** The total estimated above comes from the MOU spreadsheet, the total from the LCG projected planning spreadsheet was 200 KSI2K and 7TB Shortfall is due to delayed purchasing at RAL and Oxford 1) The estimated figures are those that were projected for LCG planning purposes: http://lcg-computing-fabric.web.cern.ch/LCG-Computing-Fabric/GDB_resource_infos/Summary_Institutes_2004_2005_v11.htm 2) Current total job slots are those reported by EGEE/LCG gstat page. Quarterly report: SouthGrid

  5. VOs supported by site 0 => not supported 1 => supported Quarterly report: SouthGrid

  6. Resources used per VO over quarter (KSI2K hours) • Information currently available from APEL • http://goc.grid-support.ac.uk/gridsite/accounting/tree/gridpp_view.php- please note these pages are • still under development! • Nb. This could be automated with an SQL/R-GMA query Quarterly report: SouthGrid

  7. Usage by VO for Tier-2 Data taken from goc accounting pages NormSumCPU (CPU hours normalised to 1KSPECint2000 Quarterly report: SouthGrid

  8. Storage resources in use per VO (TB) Difficult to provide this for the period but we can at least show *current* usage. Numbers need to be provided by site Admins (> du – sh) but this will change under dCache. Quarterly report: SouthGrid

  9. Usage by VO (CPU) Quarterly report: SouthGrid

  10. Usage by VO (jobs) Nb: This can be extracted from APEL Quarterly report: SouthGrid

  11. Progress over last quarter Quarterly report: SouthGrid

  12. Tier-2 risks Quarterly report: SouthGrid

  13. Tier-2 planning for next quarter • Setup and purchase integration test bed for SouthGrid use • Coordinate use of this cluster within UK Testzone • Install LCG-2.7.0 • Install SRM at all sites • Support some non LHC VO’s • Investigate DPM at Birmingham, then install either dcache or DPM at other sites dependent upon results of testing. • Possible new Hardware purchases. • Start some inter site performance tests • Prepare for SC4 involvement Quarterly report: SouthGrid

  14. Objectives and deliverables for last quarter Quarterly report: SouthGrid

  15. Objectives and deliverables for next quarter Quarterly report: SouthGrid

  16. Meetings, papers & effort For Tier-2 coordinator: Quarterly report: SouthGrid

  17. Summary & outlook • South Grid technical meeting held in August continued to focus sites on rapid upgrades. All sites are running the latest release and will start installing SRM’s in preparation for SC4. • There are continuing manpower issues at Bristol but this will ease shortly as the new Systems Administrator starts in October. The part HP funded post has also been finalised. • Oxford will be able to expand resources once the new computer room is built. SRIF funding for this has been obtained for the room. • Oxford new Sys Admin is in place, allowing the T2C more time to Coordinate! • Yves Coppens is providing valuable help across SouthGrid. • Bristol are now on line and it is hoped to expand their cluster once the local sys admin is in place.
