  1. Applying our GRID framework for CDF computing Santander HEP Group Rafael Marco (rmarco@ifca.unican.es) ICRB Meeting 24January 2002

  2. Our Computing Experience • On-line and offline software at LEP (DELPHI): • Fast Simulation • Physics Analysis Software: • Hot-line Interactive Event Search (IES) • NN analysis (LEP200 Higgs 4jets ) • OO software for CMS: • OSCAR framework (including Objectivity use) • Geant4 physics processes • Alignment • Recent: O/R DBMS • Objective: alternative framework to ODMG (Objectivity) • IBM DMS: beta IDS9.3 + Object Translator • Also with Oracle 9i • D.Rodriguez at CERN IT ICRB

  3. GRID activities • IFCA Santander present in EU-DataGRID • Participation in testbed (WP6): • CA provider for SPAIN • Initial cluster with 5 nodes (testbed 0) • Team setup (~5 people) + experience with Globus + DataGRID kits, etc. • Main partner for new (EU) project: CROSSGRID • Starting 1st March, driven by Poland+Spain+Germany • Use of distributed O/R DBMS • Data-mining: distributed NN (via MPI) • Santander also responsible for testbed (WP4) distributedoverthe Geant network across 11 european countries NEW Resources (hardware + personnel) ICRB

  4. Development of GRID environment for interactive applications J.Marco (CSIC) GGF3 (Frascati,Rome) 9-X-2001 ICRB

  5. CROSSGRID testbed TCD Dublin PSNC Poznan UvA Amsterdam ICM & IPJ Warsaw FZK Karlsruhe CYFRONET Cracow II SAS Bratislava USC Santiago CSIC IFCA Santander LIP Lisbon Auth Thessaloniki UAB Barcelona CSIC RedIris Madrid CSIC IFIC Valencia DEMO Athens UCY Nikosia ICRB

  6. Resources • New Infraestructure: • Cluster ~100 IBM servers (~50% available for HEP) • (dual 1.26 GHz, 640Mb-4GB RAM, 80 GB/server) + 4-way processor gatekeeper • Gigabit local backbone • Improved network connection: • 155-622 Mbps Santander-Geant • 2.5 Gbps into-Geant and to USA • Personnel (for whole HEP activity, CDF + CMS): • 2 Grid “experts” + support from university computing architecture team • 2 DBMS “experts” • Several seniors with experience in HEP offline software (installation and processing) ICRB

  7. Perspectives • Now planning our activity in CDF computing issues for next 3 years • Interested in GRID framework (sinergy for activity, infraestructure, personnel with DataGRID,CROSSGRID and also activity in CMS) • Considering mixed model: (trying to optimize funding possibilities/analysis objectives): • Resources at FNAL: • Disk on-line + CPU (basically for people at FNAL ) • Resources at Santander: • 50% of current server cluster operated in GRID framework • Dedicated on-line disk + additional computing nodes • Extremely interested in coordination with UK(GridPP) and Karlsruhe (FZK participant in CROSSGRID) +… ICRB
