Cray XE6 Optimization Workshop

Research & Science
Cray XE6 Optimization Workshop


HLRS installed HERMIT, a Cray XE6 system with AMD Interlagos processors and a performance of 1 PFlop/s. We strongly encourage you to port your applications to the new architecture as early as possible. To support such effort we invite current and future users to participate in special Cray XE6 Optimization Workshops. With this course, we will give all necessary information to move applications from the current NEC SX-9, the Nehalem cluster, or other systems to HERMIT. 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.
Monday-Wednesday, specialists from Cray will support you in your effort porting and optimizing your application on our Cray XE6.
On Thursday, Georg Hager and Jan Treibig from RRZE will present detailed information on optimizing codes on the multicore AMD Interlagos processor.
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.
