From: Rolandas Naujikas --------------------------------------------------------------- The first day: 10-10:20 Per Oster BalticGrid Objectives Partners NA2: Education Training Dissemination and Outreach NA3: Application Identification and Support NA4: Policy and Standards Development SA1: Grid Operations mange -> manage SA2: Network Resource Provisioning JRA1: SLAs, Markets and Dynamic Account Management Timeline 10:20-10:53 Bob Jones EGEE-II: A Stepping Stone to a Sustainable E-infrastructure EGEE - What do we deliver? From EGEE to EGEE-II Related EU projects EGEE-II Expertise & Resources EGEE-II Activities Main changes from EGEE to EGEE-II EGEE-II Cross-Activities Groups EGEE-II Technical Coordination Middleware structure gLite 3.0 Industry and EGEE-II Important EGEE-II Events EGEE'06 Conference Sustainability: Beyond EGEE-II e-Infrastructure for Europe Mission Key ... Summary 10:54-11:10 Lauri Anton SA1 progress Outline Objectives of SA1 Core grid services CA RA monitoring operational support logging and accounting certification testbed Help Desk validation and certification of sites Accounting and numbers RAs - 12 personal certificates - 77 host or service certificates - 49 revoked - 6 balticgrid VO: 54 Milestones MSA1.1 - done MSA1.2 P9 MSA1.3 P12 MSA1.4 P12 MSA1.5 P12 - production sites SA1 - ... Future plans Plans for next 6 months More users! More computing hours! 12:00-12:24 Mario Kadastik Operations February 2006 SFT tests April 2006 Site administrators register in GGUS to support users T2_Estonia, EENet, ITPA, VU - certified No Swedish sites in BalticGrid. Resource usage Problems with APEL accounting data publishing in R-GMA for accounting central portal. CMS going from one version to another - no CMS usage. CMS will come back in June 2006. 0.24% of first year estimate - small clusters, no applications. GAMESS and CMS should increase usage. More users will come to increase usage. Separate mailling list for users support. 12:27-13:02 Guntars Barzdins SA2: Network Resource Provisioning GEANT -> GEANT2 Latvian Academy of Science rejected Collaboration Agreement proposal from CERN BalticGrid users want to use GEANT at max, but should not destroy experience for other users Solution: Service Level Specification (SLS) Amber (Gold) - Premium IP - <10% of GEANT Rock (Silver) - BestEffort (BE), rate-limited grid+users <85% (dynamic rate-limit) Timber (Bronze) = LessThanBestEffort unused PIP, BE capacity (>5%) EGEE BAR (Bandwith Allocation and Reservation). Network Monitoring options: GridICE - nobody seems to use it. EGEE NPM GEANT2 - JRA1 - performance and measurement Issues in SA2 GEANT2 implementation schedule is slow Willingness and ability of NRENs to implement PIP and Arbitration services (SLA with EENET, LITNET). Multiple small clusters Participation in CERN/Atlas will require 12Mbps per cluster node. 14:37-14:57 Algimantas Juozapavicius NA3: Application Identification and Support High Energy Physics: CMS, LHCb, ALICE, ... ... 14:57-15:12 M.Krasovski High Energy Physics 15:12-15:24 Ilja Livenson Bioinformatics Analysis usually requires a lot of CPU time. Produce a lot of data. Problems UI is very complicated: edg-*, lcg-*, lfc-* installation is large Debugging is hard Error messages are terrible Very long time to debug (4min) Short jobs take too much of time Hardships for new users. 15:24-15:35 G. Tautvaiciene ... GAMESS 15:35-15:50 Juozas Sulckus GAMESS LitGRID/BalticGRID VO gamess created. Time and space consuming. 15:50-16:10 N. Meyer JRA1 16:10-16:20 Michał Jankowski VUS - ... 16:40-17:14 Zofija Mazurska NA2 17:15-17:49 A.Petrenko The Grid-Infrastructure for Supporting Education and Research in Ukraine --------------------------------------------------------------- The second day: 9:15-10:15 Lauri Anton If someone is in another VO than in balticgrid, better to remove from balticgrid VO. Proposition to add CMS VO to clusters. Better keep clusters used all the time. VU-MIF-LCG2 cannot follow this, because now this site is not ready for big load ... It is reasonable to add CMS VO to VU-MIF-LCG2. maui scheduler configuration for using prorities for different VOs. How about gLite 3.0 ? For gLite WMS and ... FTS ... SFT-2 problems with newer CA packages... GGUS for operational support system Certification testbed - ? Separate production sites from testbed. Use xen for testbed to consolidate resources. Logging and accounting system - APEL works at least partially. SpecInt2000 - ? Need certificate site in Latvia. Site admins should bet in balticgrid-sa1@... balticgrid-ops@... Concentrate information in one place (http://www.balticgrid.org/Internal/Wiki_folder/FrontPage/SA1). Wiki should be readable from others (without login). Security issues from LCG design. Possible security issues. If SFT is running well, that this site will be validated. Validation issues: sites have to be dedicated Conference workshop in CERN in June ? EGEE conference in September. 10:30-11:00 SA1 + SA2 13:35- SA1 + NA3 + JRA1 GAMESS VO: Manager - Juozas Sulskus (Eduardas will teach) MPI support for starting of jobs MPI support for other applications. UI - public with self registration SLA Authorization 16:15- Migrating Desktop --------------------------------------------------------------- The third day: Nothing noted because nothing interested was in this day.
