Third JUQUEEN Porting and Tuning Workshop @ JSC
Date: 2 - 4 February 2015
JUQUEEN is JSC's large special purpose supercomputer, an IBM Blue Gene/Q with 5.9 Petaflop/s. Although production on JUQUEEN started more than two years ago, users still need to make special efforts in order to get the most out of this unique research tool and get accustomed to the hard- and software.
Each year the workshop also focuses on one special user group with additional parallel talks and closer support (this does not exclude other users). The third workshop in this series invites users from earth system modelling. This will be supported by our Simulation Laboratories for Climate Science and Terrestrial Systems.
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. The workshop topics start with an introduction to JUQUEEN's hard- and software and related best practices. It will also explain the available performance and debugging tools and explain parallel I/O with its data formats. Special topics may then provide more in-depth knowledge on specific BG/Q features such as prefetching, SIMDsation with QPX, low-level networking, and active storage as well as topics close to earth system modelling.
It is highly recommended that project PIs send at least one expert on their code to this workshop.
Prerequisites
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
Each day will have a mix of lectures to choose from and hands-on sessions. The lectures will be given by local experts from Simulation Laboratories, Cross-Sectional Teams and Application Support.
The detailed agenda will be made available.Application
Registrations are only considered until the 19th of December 2014.
Due to available space, the maximal number of participants is limited.
Participants will be notified early in January 2015.
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.Further information
