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.

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. 2)RAL PPD delayed purchase due to lack of use earlier in year. * The Bristol Babar cluster transferred to Birmingham ** Delayed purchasing due to lack of computer room *** Delayed purchasing due to earlier lack of use

September 2005Quarterly report: SouthGrid Progress over last quarter SiteSuccessesProblems/Issues BirminghamUpgraded to Took part in Pre release testing of Installed Babar clusters formerly at Bristol. BristolSite installed, connected on 5 th July and now maintained by Y. Coppens and P. Gronbech. Finalizing the HP funded post Recruited Sys admin on Rolling Grant Lack of Manpower has hindered progress CambridgeUpgraded to Integrated LCG cluster in to Cam Grid Condor cluster. Still some ownership problems wrt to Condor users cf lcg pool uid’s. Apel Accounting does not yet support Condor OxfordUpgraded to SL 304 Installed LCG_2.6.0 New Sys Admin Started New Computer room is some way off and some nodes are over heating. SRIF funding has been secured to build it. The upgrade of the lcg cluster can commence as soon as the room is ready as funds are reserved. RALPPDUpgraded to Install dcache

September 2005Quarterly report: SouthGrid Tier-2 risks General risks Lack of use by casual users. Feedback from jobs that go astray is not user friendly Mitigating actions Need better training for users and more useable software. Have Integrated UI’s with Local clusters for ease of use. Institute specific risks Lack of adequate computer room space at Oxford is still a problem. Several nodes are running hot. Slow progress on building of new computer room will delay upgrade of Oxfords resources. Use of Condor at Cambridge prevents monitoring statistics?? Bristol Manpower Lack of Bristol resources Mitigating actions Condor support to be added to APEL New sys admin due to start October 1 st. Local cluster will be used, SRIF funded eScience cluster to follow with luck

September 2005Quarterly report: SouthGrid 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 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

September 2005Quarterly report: SouthGrid 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.
