Course 2013-Cray XK at HLRS, Stuttgart
|Course Cray XK
Großer Seminarraum (big seminar-room),
HLRS (Höchstleistungsrechenzentrum Stuttgart),
||2013, Monday, April 29, 9:00 - Tuesday, April 30, 16:30
||OpenACC Programming for Parallel Accelerated Supercomputers -- an alternative to CUDA from Cray perspective.
This workshop will cover the programming environment of the Cray XK7
hybrid supercomputer, which combines multicore CPUs with GPU accelerators
Attendees will learn about the directive-based OpenACC programming model
whose multi-vendor support allows users to portably develop applications
for parallel accelerated supercomputers.
The workshop will also demonstrate
how to use the Cray Programming Environment tools to identify CPU application
bottlenecks, facilitate the OpenACC porting, provide accelerated performance
feedback and to tune the ported applications. The Cray scientific libraries
for accelerators will be presented, and interoperability of OpenACC directives
with these and with CUDA will be demonstrated. Through application case studies
and tutorials, users will gain direct experience of using OpenACC directives
in realistic applications.
Users may also bring their own codes to discuss with Cray specialists or begin porting.
This workshop provides scientific training in Computational Science,
and in addition, the scientific exchange of the participants among themselves.
Monday: 9:00-9:30 local registration, 9:30 - 18:00 course
Tuesday: 9:00 - 17:00 course

HLRS is part of the
Gauss Centre for Supercomputing (GCS), which is one of the six
PRACE Advanced Training Centres (PATCs) that started in
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."
This course is a PATC course, see also the PRACE Training
For participants from public research institutions in PRACE countries,
the course fee is sponsored through the PRACE PATC program.
