SANTA CLARA, CA, Nov. 7 – The OpenACC standards group today announced increasing momentum behind the OpenACC parallel programming standard by developers, technology providers and new research institutional members. OpenACC provides a quicker and easier path to results for scientists when programming accelerators.
OpenACC is a programming standard for parallel computing using directives, designed to enable millions of scientists around the world to easily take advantage of the transformative power of computing systems equipped with heterogeneous CPU/GPU systems. OpenACC provides the easiest way for scientists, with or without extensive parallel programming expertise, to accelerate their research in a matter of hours using familiar programming models.
“2012 was an outstanding year of growth for OpenACC”, said Duncan Poole, President of the OpenACC standards group. “All of the founding members shipped products compliant to the OpenACC standard, key labs and research organizations signed up as members and developers achieved significant benefit from the portability and performance of the OpenACC directives model.”
At SC12, the members will be demonstrating OpenACC support for accelerators from AMD, Intel, and NVIDIA.
Notable among the recent applications that have benefitted from OpenACC programming:
At SC12, the members will be demonstrating OpenACC support for accelerators from AMD, Intel, and NVIDIA. "Flexibility across multiple platforms while giving options of vendors is one of the key benefits to programming with OpenACC," said Thomas Schulthess, Director of the Swiss National Supercomputing Center. "OpenACC provides support and efficiency for programming heterogeneous HPC systems, including all major architectures used in parallel computing today. OpenACC significantly enhances productivity of those scientists who need to migrate legacy software onto modern computing systems".
During 2012 the founding members--CAPS, Cray, PGI and NVIDIA, were joined by Allinea, Georgia Tech, Oak Ridge National Labs, Rogue Wave and University of Houston. These organizations will help determine the strategy and future direction of the OpenACC standard, including best practices for programming and debugging directives, the use of OpenACC at scale, as well as research intended to improve the robustness and performance of OpenACC compilers.
We are proud to announce our newest members:
OpenACC will be showcased at SC12 in Salt Lake City by all of the partners. Please visit http://www.openacc.org/sc2012 for an up to date listing of the OpenACC talks and sessions throughout the conference.
The OpenACC Application Program Interface describes a collection of compiler directives to specify loops and regions of code in standard C and Fortran to be offloaded from a host CPU to an attached accelerator, providing portability across operating systems, host CPUs and accelerators. OpenACC allows programmers to provide simple hints (directives) to the compiler, identifying which areas of code to accelerate. By exposing parallelism to the compiler, directives allow the compiler to do the detailed work of mapping the computation onto the accelerator. OpenACC enables users to create a single code base that runs on heterogeneous many-core accelerators as well as multi-core systems, making scaling application performance easier and more portable than ever. It also offers an ideal way to preserve investment in legacy applications.
In a recent solicitation, the NSF laid out needs for furthering its scientific and engineering infrastructure with new tools to go beyond top performance, Having already delivered systems like Stampede and Blue Waters, they're turning an eye to solving data-intensive challenges. We spoke with the agency's Irene Qualters and Barry Schneider about..
Large-scale, worldwide scientific initiatives rely on some cloud-based system to both coordinate efforts and manage computational efforts at peak times that cannot be contained within the combined in-house HPC resources. Last week at Google I/O, Brookhaven National Lab’s Sergey Panitkin discussed the role of the Google Compute Engine in providing computational support to ATLAS, a detector of high-energy particles at the Large Hadron Collider (LHC).
The Xeon Phi coprocessor might be the new kid on the high performance block, but out of all first-rate kickers of the Intel tires, the Texas Advanced Computing Center (TACC) got the first real jab with its new top ten Stampede system.We talk with the center's Karl Schultz about the challenges of programming for Phi--but more specifically, the optimization...

he study of climate change is one of those scientific problems where it is almost essential to model the entire Earth to attain accurate results and make worthwhile predictions. In an attempt to make climate science more accessible to smaller research facilities, NASA introduced what they call ‘Climate in a Box,’ a system they note acts as a desktop supercomputer.

At some point in the not-too-distant future, building powerful, miniature computing systems will be considered a hobby for high schoolers, just as robotics or even Lego-building are today. That could be made possible through recent advancements made with the Raspberry Pi computers.

When it comes to cloud, long distances mean unacceptably high latencies. Researchers from the University of Bonn in Germany examined those latency issues of doing CFD modeling in the cloud by utilizing a common CFD and its utilization in HPC instance types including both CPU and GPU cores of Amazon EC2.
