Nov. 5 — The OpenMP Consortium announces the release of a Technical Report detailing directives used for the execution of loops and regions of code on attached accelerators. The directives described in this Technical Report are a work in progress, and the goal of this release is to get early feedback on the proposed directives.
"We aim to provide what the marketplace has been looking for, a standard high-level way of programming accelerators across a broad base of languages and for all forms of accelerator devices", said Michael Wong, OpenMP CEO.
This Technical Report describes a model for the offloading of code and data onto a target device. Any device may be a target device, including graphics accelerators, attached multiprocessors, co-processors and DSPs. The directives detailed in the Technical Report can be used in Fortran, C, and C++.
The directives are the result of a 3-year effort by the OpenMP Consortium of HPC vendors, national labs, supercomputing centers, academic institutions and users. User experience with members' initiatives have provided important information to the effort.
Technical Report Process
The OpenMP Consortium has created a process by which Technical Reports can be released to the public. With this process, the Consortium will be able to show intermediate versions of the standardization work, and describe possible future directions or extensions to the OpenMP specification. These Technical Reports are not yet part of the OpenMP Standard, in contrast with Specifications, which are normative. Feedback can be posted on the OpenMP Forum, for which registration is required.
The OpenMP Application Program Interface (API) is a multi-platform shared-memory parallel programming model for the C, C++ and Fortran programming languages. Jointly defined by a group of major computer hardware and software vendors and the user community, OpenMP is a portable, scalable model that gives shared-memory parallel programmers a simple and flexible interface for developing parallel applications for platforms ranging from multicore systems and SMPs, to embedded systems.
Incorporated in 1997, The OpenMP ARB is the non-profit corporation that owns the OpenMP brand, oversees the OpenMP specification and produces and approves new versions of the specification. Further information can be found at http://www.openmp.org/.

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...
Although Horst Simon was named Deputy Director of Lawrence Berkeley National Laboratory, he maintains his strong ties to the scientific computing community as an editor of the TOP500 list and as an invited speaker at conferences.

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.

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.
