Jülich BlueGene/P Extreme Scaling Workshop

14-16 February 2011,
Jülich Supercomputing Centre

Jülich BlueGene/P JUGENE

The purpose of the workshop is to give application teams an opportunity to scale their code across the full Blue Gene/P system JUGENE, which consists of 72 racks with a total of 294,912 cores - the highest number of cores world-wide. Appropriate hardware, software and support personnel will be provided to help to accomplish this task.

Application process

The attendees of the workshop will be selected from written proposals which need to be submitted before November 30th, 2010. Participation is limited to 6 to 8 application teams. Selection criteria are the confidence that the code could scale across 72 racks (or at least a large portion of it), that the JUGENE infrastructure (OS, compilers, libraries) support the user request, and on the scientific impact that the code could produce. Applicants who have not yet participated in one of the previous scaling workshops are preferred.

To sign up for the workshop, send a 1 to 2 page proposal per email to sc@fz-juelich.de; please use 'ScalingWS11' as part of the subject.

The proposal should contain a

  • description of the application to be scaled,
  • scaling plots, which shows a good scaling of at least up to 64k tasks
  • code requirements (e.g. special libraries, compiler versions, I/O needs, ... beyond a "standard"
  • BlueGene/IBM setup)
  • contact data
  • references

Note: If accepted, we expect that at least one team member will register and attend for the workshop.

Important dates

Final submission deadline: Nov 30, 2010
Notification of acceptance: Dec 07, 2010
Machine access for preparations: Jan 15, 2011
Workshop: Feb 14 to 16, 2011

Participants

Ten teams from all over the world got selected to participate in the workshop and tried to scale their applications to the full system (72 rack) scale.
