I Brazilian LHC Computing Workshop Welcome

Purpose Discuss the computing needs of each experiment and establish the amount of computing resource that should be available in Brazil for processing the LHC data Make a strategic plan to guarantee that  the different middleware and software could smoothly run in all the resources Pursue the real integration of the resources in a distributed LHC Tier 2 ( Tier 1) facility Discuss about a unified administrative/technical structure to present ourselves as a single, coherent and organized group to CERN and to our financial agencies Establish guidelines for new resource and infrastructure projects 30/Mar/2006 S.

OSG X LCG X AliEn X Dirac X … LHCb: Very small participation from US Syracuse University: 11 out of 654 members Focused on European solutions LCG, EGEE  EELA (E-Infrastructure shared between Europe and Latin America) Using DIRAC Grid Framework for LHCb Distributed Infrastructure with Remote Agent Control Python based grid job management system Follows Condor model of job pools Service Oriented Architecture Alice Alice Environment Starting point for developing the gLite, next generation of grid middleware developed by EGEE Projects using AliEn ALICE is using for simulation, reconstruction and distributed analysis of physics data Panda at GSI, Darmstadt is using for simulation Mammogrid, European Federated Mammogram Database AliEn will be progressively interfaced to emerging products from both Europe and the US http://www.cern.ch/paterson/CHEP06_DIRAC_SKP.ppt http://www.eu-eela.org/ http://alien.cern.ch 30/Mar/2006 S.

A Distributed Infrastructure The Evaluation Panel agrees with the idea of establishing a common Nordic grid. The Nordic countries, individually, appear to have difficulties with establishing the sufficient critical mass to become attractive collaboration partners in the larger grid projects in Europe and the rest of the world. But the establishment of Nordic Data Grid Facility will ensure – for scientist in the Nordic countries – a grid infrastructure which is of sufficient critical mass to join various scientific projects needing grid and high performance computing in Europe and the rest of the world.
