Developing and Running MPI applications on the EGEE and Int.EU.Grid infrastructures

10 Sept 2007, 09:00 → 11 Sept 2007, 18:00 Europe/Zurich

Lloyd Institute (Trinity College Dublin)

Brian Coghlan (Trinity College Dublin), Stephen Childs (Trinity College Dublin)

This two day event will bring together experienced MPI application developers from EGEE, int.eu.grid and CosmoGrid. The aim will be to show how to adapt MPI code for usage on these grids. In addition to comprehensive treatment of basic MPI usage, we will also introduce advanced topics such as MPI tool support, visualisation and computational steering.

09:30 → 10:15 EGEE support for MPI

In this session we will describe the current support for MPI applications in EGEE including: current issues, recommended usage, and future developments.

10:15 → 10:45 Coffee Break

10:45 → 12:15 MPI Practical

This MPI practical gives the user a hands on look at developing and running MPI applications on the Grid. We will cover the following issues: searching the information system for MPI-compatible sites, developing JDLs and wrapper scripts, submitting applications using mpi-start, interaction with Grid storage.
