University of Houston Joins the OpenMP Effort

The University of Houston (UH) has joined the OpenMP Consortium, a group of leading hardware and software vendors and research organizations creating the standard for the most popular shared-memory parallel programming model in use today.

“We are excited to join the OpenMP family as an academic member”, says Barbara Chapman, Professor of Computer Science and director of the Center for Advanced Computing and Data Systems (CACDS) at UH. “Through cOMPunity, we have been involved since the beginning. With this new membership, we will continue to engage with the OpenMP community.”

“This is a great step forward for the UH HPCTools research group. We look forward to continuing our efforts to support standardization of OpenMP, to providing reference implementations through the OpenUH compiler and proposing new features”, says Yonghong Yan, Research Assistant Professor at UH.

The University of Houston is located in the Houston metropolitan area, world headquarters for the energy industry and home to the Texas Medical Center. UH HPCTools Research group, led by Chapman and Yan, performs research on parallel programming models, compiler technologies, and HPC applications and systems. CACDS provides HPC resources at UH.

“I wish to warmly welcome UH to OpenMP, although they are no stranger, with a rich and deep history of working with and contributing to OpenMP as well as research regarding OpenMP” says Michael Wong, OpenMP CEO.

The OpenMP ARB now has 14 permanent members and 12 auxiliary members. Permanent members are vendors with a long-term interest in creating products for OpenMP, while auxiliary members have an interest in OpenMP and do not create or sell products.

9th OpenMP Workshop Sept 16-18 in Australia

IWOMP 2013 Canberra

9th International Workshop on OpenMP — September 16-18, 2013

The »International Workshop on OpenMP (IWOMP) is an annual workshop dedicated to the promotion and advancement of all aspects of parallel programming with OpenMP. It is the premier forum to present and discuss issues, trends, recent research ideas and results related to parallel programming with OpenMP. The international workshop affords an opportunity for OpenMP users as well as developers to come together for discussions and sharing new ideas and information on this topic.

IWOMP 2013 will be a three-day event. The first day will consist of tutorials focusing on topics of interest to current and prospective OpenMP developers, suitable for both beginners as well as those interested in learning of recent developments in the evolving OpenMP standard. The second and third days will consist of technical papers and panel sessions during which research ideas and results will be presented and discussed.

OpenMP 3.1 Support in Clang Announced

The Clang community has announced the availability of a full OpenMP 3.1 support implementation in the Clang compiler:

“This project implements OpenMP support in the Clang C language family front-end for the LLVM compiler. The current scope of the project is to support the OpenMP 3.1 specification.”

The project is hosted here:

It is based on clang 3.3 (and will be updated as new clang/llvm releases become available); also, we plan to eventually contribute everything to the clang trunk (initial patches have already been committed). This implementation supports 3.1 version of OpenMP standard in full; it passes all OpenMP tests we tried with it so far (this includes OpenMP Validation Suite from OpenUH Research Compiler, SPEC OMP2012 and internal Intel test suites). Performance-wise, it demonstrates similar gains and scalability as other compilers with OpenMP support.

OpenMP Consortium Announces Red Hat As New Member

26 vendors and research organizations collaborating on standard parallel programming model

Red Hat has joined the OpenMP Architecture Review Board (ARB), a group of leading hardware and software vendors and research organizations creating the standard for today’s most prevalent shared-memory parallel programming model.

“As a leading proponent of OpenMP, Red Hat is thrilled to officially join the OpenMP ARB,” said Mike Werner, senior director, ISV and developer ecosystems, Red Hat. “We believe that the OpenMP model is important in simplifying parallel processing efforts, and implement the standard in Red Hat Enterprise Linux, including Red Hat Enterprise Linux 6.”

Red Hat is the world’s leading provider of open source solutions, using a community-powered approach to reliable and high-performing cloud, Linux, middleware, storage and virtualization technologies. The company’s membership in the OpenMP ARB exemplifies a long-standing commitment to the development and support of tools and standards that help advance open source technology and its adoption within the developer community.

“I am very pleased to have Red Hat participate in the OpenMP family”, said Michael Wong, OpenMP CEO. “Red Hat has a long tradition of supporting OpenMP with rapid GCC implementations and strong commitment to open standards. This will help to ensure deeper collaboration.”

The OpenMP ARB now has 14 permanent members and 12 auxiliary members. Permanent members, including Red Hat, are vendors who have a long-term interest in creating products for OpenMP, while auxiliary members are organizations with an interest in the standard but that do not create or sell OpenMP products.
