»Clang 3.7 will have full OpenMP 3.1 support

For the last several years, the OpenMP team has been working in collaboration with Intel, IBM and many other companies to add OpenMP support into clang/llvm.

Over the last 2 years, more OpenMP support has appeared in clang/llvm in llvm 3.5, 3.6 releases.

Now we can announce that this collaboration has achieved full OpenMP 3.1 support in clang/llvm 3.7, which will be released at the end of August.  Several features of the OpenMP 4.0 specifications are already supported in clang 3.7, and work continues on OpenMP 4.0 for clang 3.8.

The full details are on Michael Wong’s blog.

»OpenMPCon/IWOMP 2015 Developers Conference will be in Aachen, Germany

Michael Wong, the OpenMP ARB’s CEO, writes on his blog:

It is with great pleasure that I wish to announce OpenMPCon 2015 which is paired and co-located with the sister conference IWOMP 2015 on Sept 28-Oct 2. As OpenMP evolves rapidly with more releases to match pace with the rapidly evolving Hardware and Parallel world (one Technical Report followed by one ratified Specification every year; we are nearly delivering OpenMP 4.1 which you can preview at OpenMPCon), OpenMPCon aims to be the central place for the latest OpenMP Language development, tutorial, tips and tricks, as well developers connecting with language designers, and compiler/tool vendors.  This will be done on Monday and Tuesday, and partially on Wednesday where the tutorial is shared with IWOMP but can be attended by both conferences.

IWOMP continues its rich history of academic refereed journal research paper presentations on Thursday and Friday on the latest research that will move OpenMP forward into the next generation, as well as offering experimental data on current OpenMP usage that will allow the Language Committee to refine existing constructs. These two combined conferences form a very healthy way for OpenMP to remain agile and moving forward.
