  1. 51. Profiling Post-GRID analysis
    Dr Akira Shibata (New York University)

    1. Computing Technology
    Parallel Talk
    An impressive amount of effort has been put in to realize a set of frameworks to support analysis in this new paradigm of GRID computing. However, much more than half of a physicist's time is typically spent after the GRID processing of the data. Due to the private nature of this level of analysis, there has been little common framework or methodology. While most physicists agree to use...

    1. Computing Technology
    Parallel Talk
    The LHC machine has just started operations. Very soon, Petabytes of data from the ATLAS detector will need to be processed, distributed worldwide, re-processed and finally analyzed. This data-intensive physics analysis chain relies on a fabric of computer centers on three different sub-grids: the Open Science Grid, the LHC Computing Grid and the Nordugrid Data Facility--all part of the...

  3. 57. The CMS Tier 0
    Ian Fisk (Fermi National Accelerator Laboratory (FNAL))

    1. Computing Technology
    Parallel Talk
    The CMS Tier 0 is responsible for handling the data in the first period of it's life, from being written to a disk buffer at the CMS experiment site in Cessy by the DAQ system, to the time transfer completes from CERN to one of the Tier1 computing centres. It contains all automatic data movement, archival and processing tasks run at CERN. This includes the bulk transfers of data from Cessy...

  4. 45. Data transfer infrastructure for CMS data taking
    Mr Ricky Egeland (University of Minnesota – Twin Cities, Minneapolis, MN, USA)

    1. Computing Technology
    Parallel Talk
    The CMS PhEDEx (Physics Experiment Data Export) project is responsible for facilitating large-scale data transfers across the grid ensuring transfer reliability, enforcing data placement policy, and accurately reporting results and performance statistics. The system has evolved considerably since its creation in 2004, and has been used daily by CMS since then. Currently CMS tracks over 2 PB of...
