Jülich BlueGene/P Porting, Tuning, and Scaling Workshop

22-24 April 2008
Jülich Supercomputing Centre

Jülich BlueGene/P JUGENE 2008Jülich BlueGene/P JUGENE 2008, 16 Racks
Source: Forschungszentrum Jülich

IBM, BG consortium, Totalview, and JSC experts will provide first-hand knowledge on how to port applications to the Blue Gene/P system, debug them on large numbers of nodes, and how to scale existing Blue Gene codes to the new full 16-rack Blue Gene/P system of JSC.

The workshop is open to everyone (not just users of JSC or even IBM systems)!

Goals

In this workshop you will:

  • Get a first-hand overview of the Blue Gene/P architecture from IBM representatives
  • Begin hands-on porting and tuning of your application with IBM and JSC staff assistance
  • Learn how to debug applications running on a large number of nodes from Totalview experts
  • Understand transitioning from the Blue Gene/L to the Blue Gene/P
  • Be able to investigate scalability of your code and perform scaling experiments upto the full 16-rack (65.536 cores) system
    [For projects with an already scalable Blue Gene/L application code]
