5. Tony Doyle - University of Glasgow 27 June 2006Collaboration Meeting All key objectives have been reached for the end of 2005 and installation is now proceeding smoothly. Three quarters of the machine has been liberated for magnet installation and interconnect work is proceeding in 2 octants in parallel. Magnet installation is now steady at 25/wk. Installation will finish end March 2007. The machine will be closed in August 2007. Every effort is being made to establish colliding beams before the end of 2007 at reduced energy. The full commissioning up to 7 TeV will be done during the winter shutdown ready for a Physics run at full energy in 2008. LHC?

6. Tony Doyle - University of Glasgow 27 June 2006Collaboration Meeting The Service Challenge programme this year must show that we can run reliable services Grid reliability is the product of many components – middleware, grid operations, computer centres, …. Target for September –90% site availability –90% user job success Requires a major effort by everyone to monitor, measure, debug First data will arrive next year NOT an option to get things going later Too modest? Too ambitious? Challenges for 100 Computing Centres in 20 Countries Les Robertson HEPiX Meeting, Rome, 5 April 2006 WLCG?

11. Tony Doyle - University of Glasgow 27 June 2006Collaboration Meeting Capacity Planning Considerations… The Tier-1/A capacity originally planned to be available for 06Q1 was put into production in late April 2006 (CPU). The disk capacity is scheduled to be available in early August. The new SL8500 tape robot began providing a production service in March. The first three T10K tape drives for the GridPP tape service are expected to be delivered in July together with 200TB of tape media. The SL8500 robot will be upgraded from 6000 to 10000 slots (paid for by CCLRC). Tenders for 500 kSI2k and 237 TB of disk at the end of June. Good progress is being made on the deployment of CASTOR2 (providing HSM capability and SRM interface to storage) which remains on schedule for a production service in September. For the Tier-2 centres, additional capacity was made available in 06Q1, with the incorporation of capacity at two additional large centres (Manchester and Liverpool). The available CPU in the first quarter increased to 3703 kSI2k such that 75% of the MoU commitment has now been met, with disk increasing to 263 TB. CPU utilisation of this much larger resource was 23% with overall disk utilisation improved at 61% in 06Q1. Additional capacity improvements are envisaged at Bristol, Cambridge, Glasgow and QMUL during this year. The GridPP resource utilisation outturn for 2005 updated to include 06Q1 is available from http://www.gridpp.ac.uk/docs/gridpp3/GridPP-PMB-92-Utilization.doc.http://www.gridpp.ac.uk/docs/gridpp3/GridPP-PMB-92-Utilization.doc

15. Tony Doyle - University of Glasgow 27 June 2006Collaboration Meeting Tier-0 to Tier-1 worldwide data transfers > 950MB/s for 1 week peak transfer rate from CERN of >1.6GB/s Need high data rate transfers to/from CERN as a routine activity

18. Tony Doyle - University of Glasgow 27 June 2006Collaboration Meeting Moving Files… keeping track Volatile –Temporary and sharable copy of an MSS resident file –If not pinned it can be removed by the garbage collector as space is needed (typically according to LRU policy) Durable –File can only be removed if the system has copied it to an archive Permanent –System cannot remove file Users can always explicitly delete files The experiments only want to store files as permanent –Even scratch files  will be explicitly removed by experiment

26. Enabling Grids for E-sciencE EGEE-II INFSO-RI-031688 Talk Title EGEE-I Review “The project was successfully completed and followed high standards with respect to project management, software development, integration and operations. The objective of a reliable production grid of significant size, which is professionally operated, monitored, maintained and continuously expanded, has been achieved. The average number of daily jobs and the number of involved sites are impressive. The EGEE brand was successfully introduced world-wide. The training efforts and achievements continued to be impressive. The successful merge of LCG and gLite middleware distributions provides a solid foundation for the future evolution of the EGEE middleware. The project management structure very well adapted to the evolving requirements of the project. EGEE successfully fulfilled its role as an incubator and as a driver for linking European grid projects to world-wide grid activities. The stronger involvement in international standardization efforts is well recognized, although the impact could have been stronger and more visible. For instance, the VO Management Service (VOMS) is becoming a de facto standard in many major research grids world-wide, but EGEE's contributions are not sufficiently well known. All deliverables are of high quality and more appropriately sized and focused than in the two previous reviews. All deliverables are accepted. There were no notable deviations from the work plan. Resources and major costs were necessary and of reasonable economy.” EGEE-I worked at many levels

27. Enabling Grids for E-sciencE EGEE-II INFSO-RI-031688 Talk Title Grids and Business – key points Trust - Not use to sharing resources Security - Sensitive data with sensitive applications Business models – what can be charged for as a service Guaranteed QoS – Service Level Agreements Accounting - tracking resources usage in multi-admin context Standards – to encourage long-term investment Applications – need to support legacy applications Portability – across multiple platforms and implementations Open source support – robust reference implementation Software license management – how to generate revenue in a grid context EGEE-II provides an excellent framework for collaborating with business on these subjects
