Abstract

The announcement late 2011 of the new OpenACC directive-based programming standard supported by CAPS, CRAY and PGI compilers has open up the door to more scientific applications that can be ported on many-core systems. Following a porting methodology, this talk will first review the principles of programming with OpenACC and then the advanced features available in the CAPS compilers to further optimize OpenACC applications: library integration, tuning directives with auto-tune mechanisms to build applications adaptive to different GPUs. CAPS compilers use hardware vendors' backends such as NVIDIA CUDA and OpenCL making them the only OpenACC compilers supporting various many-core architectures.
