OpenACC Programming for Parallel Accelerated Supercomputers

Abstract

This workshop will cover the programming environment of the Cray XK6 hybrid supercomputer, which combines multicore CPUs with GPU accelerators (http://www.cray.com/Products/XK6). Attendees will learn about the directive-based OpenACC programming model (http://www.openacc-standard.org), 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.

PRACE PATC

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.
