SANTA CLARA, Calif., March 14 — The OpenACC Architecture Review Board today announced 23 OpenACC related sessions and tutorials that will be held during the GPU Technology Conference (GTC) at the San Jose Convention Center, March 18-21.
OpenACC provides a quicker, easier and more portable path to detailed results for programmers using accelerators across a wide range of disciplines.
Highlights of OpenACC sessions taking place at GTC 2013 include:
More information about OpenACC sessions can be found at http://www.openacc.org/events/calendar as well as further details on partners and membership related information. The complete GTC event information can be found at http://www.gputechconf.com/page/home.html.
"The extensive collection of OpenACC sessions at GTC reflects the dramatic growth in the number of programmers who are adopting the standard," said Duncan Poole, president of the OpenACC Standards Group. "The sessions will provide OpenACC programming tips and best practices from industry experts and will give attendees a unique opportunity to network with individuals from a range of fields that are experiencing the tremendous impact of accelerated computing in their work."
The updated OpenACC version 2.0 specification will be available for public comment on Fri., March 15 at http://www.openacc.org/sites/default/files/OpenACC-2.0-draft.pdf. This version adds several important new features to the specification, including support for procedure calls and separate compilation, nested parallelism and multiple device types.
OpenACC is a programming standard for parallel computing using directives, designed to enable researchers, scientists and engineers around the world to easily take advantage of the transformative power of computing systems equipped with heterogeneous CPU/Accelerator 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.
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...

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.

Program provides cash awards up to $10,000 for the best open-source end-user applications deployed on 100G network.
05/10/2013 | Cleversafe, Cray, DDN, NetApp, & Panasas | From Wall Street to Hollywood, drug discovery to homeland security, companies and organizations of all sizes and stripes are coming face to face with the challenges – and opportunities – afforded by Big Data. Before anyone can utilize these extraordinary data repositories, however, they must first harness and manage their data stores, and do so utilizing technologies that underscore affordability, security, and scalability.
