Local organizer: Dr. Dirk Brömmel

The commissioning of the new Blue Gene/Q petaflop supercomputer JUQUEEN marked another quantum leap in supercomputer performance at JSC. At the same time, it was recognised that special efforts by the users are necessary in order to get the most out of this unique research tool.

The aim of this hands-on workshop is to support current users of JUQUEEN in porting their software, in analysing its performance, and in improving its efficiency.

It is highly recommended that project PIs send at least one expert on their code to this workshop.


Participants should belong to a currently active simulation project on JUQUEEN (project-ID!) and should already have an active user account (user-id!). Test runs during the workshop will be done on the participants' own project accounts.

In order to gain maximum benefit from this workshop, participants should have an in-depth (hands-on) knowledge of the algorithms and codes used in their project.

In addition, we also ask participants to prepare a test case to evaluate the initial performance of their code and to monitor the progress.

General outline of the workshop

Day 1, morning: Overview Presentations

Day 1, afternoon and following days

  • Work on own application: porting, analysis, and optimisation

  • Support by experts from:

    • Performance Tools group
    • IBM
    • Simulation Labs
    • JSC application support
  • Talks and Breakout-Sessions

    • special interest group computational fluid dynamics
    • specialized in-depth topics for Blue Gene

The detailed agenda is available as a link on the left hand side.


Registrations are only considered until the 12th of January 2014.
Due to available space, the maximal number of participants is limited.
Participants will be notified early in January 2014.

Note that in the application form we ask for some information about your project and code in order to better plan the workshop program. This workshop is a Prace Advanced Training Centres (PATC) course.
