Presentation Transcript

  1. CDF computing in the GRID framework in Santander Santander HEP GroupIFCA (Instituto de Fisica de Cantabria, CSIC-UC) Teresa Rodrigo, Iván Vila, Alberto Ruiz, Rocio Vilar, Gervasio Portilla, Jonatan Piedra, Javier Fernández, Javier Cuevas Jesús Marco (marco@ifca.unican.es) ICRB Meeting 4September 2002

  2. GRID activities IFCA Santander present in EU-DATAGRID • Participation in testbed (WP6): • CA provider for SPAIN • Team (~5 people) + experience with Globus + EDG (1.2.0) IFCA/CSIC main partner for EU-CROSSGRID project • Use of distributed O/R DBMS • Data-mining: distributed NN (via MPI) • Responsible for testbed (WP4) distributedoverthe Geant network across 11 European countries National initiative: LCG-ES project • Close to Tier-2 level resources, CMS “oriented”, including : • MC production farm • Physics Analysis NEW Resources (hardware + personnel) CDF Computing in the GRID Framework in Santander

  3. Available Resources • “New” Infrastructure: • 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 • Local Disk and Tape ( 10 Tb on disk, 10 Tb on LTO robot) • Improved network connection: • 155 Mbps Santander-Geant • 2.5 Gbps into-Geant and to USA • Personnel (for whole GRID activity): • 2 Grid “experts” + support from university computing architecture team • 2 DBMS “experts” • Several seniors with experience in HEP offline software (installation and processing) CDF Computing in the GRID Framework in Santander

  4. Perspectives • Need to use the GRID framework • sinergy for activities, infraestructure use, personnel in DATAGRID/CROSSGRID and also activity in CMS • Funding requested for our activity in CDF computing: • 1 dedicated person (starting before end of the year) • 50 k$/year on hardware (double by 2004 current resources) • Mixed model: (trying to optimize funding possibilities/analysis objectives): • Minimal resources at FNAL: • Disk on-line + CPU (basically for people at FNAL ) • Shared resources at Santander: • 50% of current server cluster operated in GRID framework • Upgrade of on-line disk + additional computing nodes + tape CDF Computing in the GRID Framework in Santander

  5. Interest of Collaboration • Physics channels: • B-physics, top and Higgs searches • Possible Scheme (to be considered in discussion of contribution to CDF): • MC Production in Santander GRID cluster (including limited tape storage) • Production data analysis jobs in Santander also via GRID • Initial user analysis jobs tested at Fermilab with limited resources • Deploy a powerful Interactive Physics Analysis Facility in GRID framework, including significative resources in Santander • Contribute to CDF Grid Activities with expertise on testbeds, and participating in EU-US initiatives CDF Computing in the GRID Framework in Santander
