Not so long ago, there was a question whether exascale supercomputers would be built from a very large number of thin nodes containing only modest amounts of parallelism or a smaller number of fat nodes powered by specialized accelerators and powerful manycore processors. …
I have been frequently asked when the OpenMP and OpenACC directive APIs for parallel programming will merge, or when will one of them (usually OpenMP) will replace the other. …
OpenACC is one of the prongs in a multi-prong strategy to get people to port the parallel portions of HPC applications to accelerators. …
On today’s episode of “The Interview” with The Next Platform we talk with Doug Miles who runs the PGI compilers and tools team at Nvidia about the past, present, and future of OpenACC with an emphasis on what lies ahead in the next release. …
Academic centers and government agencies often design and write their own applications, but some of them and the vast majority of enterprise customers with HPC applications usually depend on third parties for their software. …
Across the HPC community, commercial firms, government labs and academic institutions are adapting their code to embrace GPU architectures. …
OpenACC’s global attraction can be seen in the recent February 2017 OpenACC mini-hackathon and GPU conference at KAUST (King Abdullah University of Science & Technology) in Saudi Arabia. …
Although there will be some meaty hardware and systems news in high performance computing over the course of 2016, this will be the year that programming models for HPC systems take center stage, especially as large supercomputing sites prepare for their first waves of pre-exascale machines. …
The choice of programming tools and programming models is a deeply personal thing to a lot of the techies in the high performance computing space, much as it can be in other areas of the IT sector. …
While nothing can beat the notoriety of the long-standing LINPACK benchmark, the metric by which supercomputer performance is gauged, there is ample room for a more practical measure. …
