Cray XE6 Optimization Workshop

Cray XE6 Optimization Workshop


HLRS installed HERMIT, a Cray XE6 system with AMD Interlagos processors and a performance of 1 PFlop/s. Currently, the system is extended by a Cray XC30 system. We invite current and future users to participate in this special course on porting applications to our Cray architectures. HERMIT provides our users with a new level of performance. To harvest this potential will require all our efforts. We are looking forward to working with our users on these opportunities.

The first three days, specialists from Cray will support you in your effort porting and optimizing your application on our Cray XE6/XC30. On the fourth day, Georg Hager and Jan Treibig from RRZE will present detailed information on optimizing codes on the multicore AMD Interlagos and Intel Sandy Bridge processors.

This workshop provides scientific training in Computational Science, and in addition, the scientific exchange of the participants among themselves.
HERMIT is available in Germany and Europe through this link.

HLRS is part of the Gauss Centre for Supercomputing (GCS), which is one of the six PRACE Advanced Training Centres (PATCs) that started in Feb. 2012. The mandate for the PATCs is as follows:
"The PRACE Advanced Training Centres will serve as European hubs of advanced, world-class training for researchers working in the computational sciences." (see D3.2.3)
This course is a PATC course, see also the PRACE Training Portal and Events. For participants from public research institutions in PRACE countries, the course fee is sponsored through the PRACE PATC program.

Cancelation policy

If you cannot come to the course, please send an email to the organizer as soon as possible. This would allow us to accept additional participants from the waiting-list. There is no cancelation fee.
NO-SHOW: Registered persons that do not cancel and do not show up without any reasons are blocked for the next year on any of our workshops (because it is to expensive to produce unused copies of the slides for them).


maximum of 50 participants in Stuttgart (according to the seats in the rooms).


Each participant will get a paper copy of all slides.
