»OpenMP 4.0 Release Candidate 1 Now Available

OpenMP, the de facto standard for parallel programming on shared memory systems, continues to extend its reach beyond pure HPC to include embedded systems, real time systems, and accelerators.

Release Candidate 1 of the OpenMP 4.0 API specifications currently under development is now available for public discussion.  This update includes thread affinity, initial support for Fortran 2003, SIMD constructs to vectorize both serial and parallelized loops, TASKGROUP, user-defined reductions, and sequentially consistent atomics.

The OpenMP ARB plans to integrate the Technical Report on directives for attached accelerators, as well as more new features, in a final Release Candidate 2, to appear sometime in the first Quarter of 2013, followed by the finalized full 4.0 API specifications soon thereafter.

The 4.0 Release Candidate API specifications (4.0RC1) and the Technical Report (TR1) PDFs can be downloaded from the »OpenMP Specifications page.

A new public »discussion forum has also been created to discuss the 4.0RC1 and the TR1.

»The OpenMP Consortium Releases First Technical Report

Champaign, Illinois - Nov 5, 2012 - 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.

The Technical Reports are located at

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.

»Language Committee Meeting in Toronto

There will be a meeting of the OpenMP Language Committee in Toronto at the downtown Holiday Inn, Oct 22-25, 8:00 am-6 pm.

Our main aim is close on the OpenMP 4.0 Draft, which is to be released for Public Comment in November at the SuperComputing 12 conference and exhibition in Salt Lake City.

Topics to be covered in this meeting include: Tasking, Fortran 2003 base language support, Affinity, Accelerators, Error Models, and SIMD.

Three special lunch time sessions will discuss: The Future of OpenMP, OpenMP Tools, and the IBM/Rice Doacross proposal.

These meetings are open to the public. However, if you wish to attend the meeting, please notify us at

The meeting will be held at the Holiday Inn Toronto Downtown Centre, 30 Carlton Street, Toronto, Canada. (416) 977-6655

Future meetings of the OpenMP Language Committee are planned for January 2013 in Houston, Texas, and in May (host site to be determined).

»aiXcelerate 2012 - Tuning for big SMP HPC Workshop

RWTH Aachen Unversity

Monday, Oct 8 - Wednesday, Oct 10, 2012

Center for Computing and Communication

RWTH Aachen University (Aachen, Germany)

This tuning workshop will cover tools and methods to program big SMP systems in detail.

Attendees are kindly requested to prepare and bring in their own code, if applicable. It is recommended to have good knowledge in MPI and/or OpenMP and the programming language (C/C++/Fortran) of the code. If you do not have an own code, but you are interested in the presented topics, you can work on prepared exercises during the lab time.
The machines are all operated under Linux, so all codes need to run there.
Participants from RWTH Aachen university are welcome, but also participants from other universities or  companies.
The presentations will be given in English.
