Cray enhances coprocessor and accelerator programming with support for OpenACC 2.0

8 Oct 2013 Seattle - Cray Inc. has introduced new OpenACC 2.0 support for directives-based programming of accelerators and coprocessors in Cray supercomputers. Leveraging years of successful production accelerator experience and supercomputing domain knowledge, the Cray OpenACC programming implementation now supports NVIDIA Tesla GPU accelerators and Intel Xeon Phi coprocessors on the Cray XC30 series of supercomputers.

In an ongoing effort to make it easier for programmers to take advantage of parallel computing, the OpenACC parallel programming standard is a simple, directives-based approach enabling the acceleration of applications on hybrid many-core and multi-core processing systems. The OpenACC approach provides simplified programming of accelerators and coprocessors, wide application support, and flexible and standards-compliant results. OpenACC 2.0 support is delivered for the Cray compiler through the latest release of the Cray Programming Environment.

"Congratulations to Cray for releasing the first compiler with complete support for OpenACC 2.0", stated Duncan Poole, president of OpenACC. "The objective of OpenACC is to provide a programming API that performs well on all types of accelerators and CPUs. The OpenACC organisation is responding quickly to create an open standard that is architected to ensure developer code is portable, with good performance on all types of accelerators and CPUs. This rapid pace of leadership further distances the OpenACC specification from similar efforts."

"Software tools that are optimized for supercomputers are an imperative for programmers to get every ounce of power and performance efficiency out of a supercomputing system", stated Peg Williams, Cray's senior vice president of high performance computing systems. "Cray's support for version 2.0 of the OpenACC Application Programming Interface demonstrates our commitment to providing the OpenACC user community with the ability to develop applications that are easily portable across platforms while eliminating the need for multiple versions of source code."

Established in 2011, OpenACC is a non-profit organisation founded with the purpose of advancing directives-based programming methodology for enabling high performance accelerators and coprocessors in hybrid supercomputing systems. By exposing parallelism to the compiler, directives allow the compiler to do the detailed work of mapping the computation onto the accelerator. Offloading specific loops and regions of code from the CPU to an attached accelerator can greatly improve performance while simultaneously significantly reducing power consumption.

Cray is a co-founding member, and the OpenACC organisation has been joined by numerous high performance computing (HPC) organisations since, including users, computing centres and educational institutions, as well as silicon and software vendors.

The Cray implementation of OpenACC 2.0 delivers on user productivity requests and optimization requirements, including dozens of new construct updates, enhancements and improvements. More information on OpenACC and the 2.0 specification can be found at www.openacc-standard.org .

To learn more about the OpenACC 2.0 enhancements for the Cray XC30 supercomputers, you can register for an upcoming webinar , which will be held on Wednesday, October 30, 2013 at 10:00 a.m. PDT.
