Cray Enhances Coprocessor and Accelerator Programming With Support for OpenACC 2.0

Cray Enhances Coprocessor and Accelerator Programming With Support for OpenACC 
SEATTLE, WA -- (Marketwired) -- 10/08/13 --  Global supercomputer
leader Cray Inc. (NASDAQ: CRAY) today 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(R) Tesla(R) GPU accelerators and Intel(R) Xeon Phi(TM)
coprocessors on the Cray(R) XC30(TM) 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," said 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
organization 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
"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," said 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 organization 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 organization has been
joined by numerous high performance computing (HPC) organizations
since, including users, computing centers 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

supercomputers, please register for an upcoming webinar, which will
be held on Wednesday, Oct. 30, 2013 at 10:00 a.m. PDT.
