    MPIWG/int.eu.grid MPI workshop

    → Europe/Zurich
    Trinity College Dublin, Ireland

    Trinity College Dublin, Ireland
    Childs, S.
    Description
    This hands-on workshop will bring together site administrators, VO experts and MPI specialists from the EGEE and int.eu.grid projects to discuss and test proposals for improving MPI support on the Grid. The primary goal is to agree on configuration procedures for sites so that users can use standard techniques to discover MPI-capable sites and submit MPI jobs on the EGEE and int.eu.grid infrastructures. We also hope to identify potential improvements to the core middleware that would facilitate submission and management of MPI jobs.

        Hands-on session 1

        In this session we will work directly with testbed sites to
        develop and validate an MPI configuration for EGEE sites. We
        will probably break into three groups:

        • YAIM
        • Quattor
        • Applications
    • Tuesday 12 December
      • 09:00 → 10:30
        Hands-on session 2

        Continuing with yesterday's work.

      • 11:00 → 12:30
        Review progress and assign actions

        In this session, we will review the progress made in the
        technical sessions and assign actions. These will probably
        include:

        • Updating documentation: GOC wiki, EGEE user guide
        • Liaising with SA3 YAIM team to integrate MPI site config
        • Liaising with SAM team to integrate MPI test
        • Integrating MPI config into Quattor
        • Completing and circulating MPI WG report
      • 14:00 → 15:30
        Workload management system issues

        There are a number of features of the workload management
        system that place limitations on MPI users. We will briefly
        present these problems and discuss possible solutions. We
        hope to formulate recommendations for any future work on MPI
        by the WMS developers.

      • 16:00 → 17:30
        Future directions

        What we would like to see happen to make MPI on the Grid
        work really well for users. Input from int.eu.grid would be
        particularly welcome here.
