[LLVMdev] OpenMP 3.1 Support Implementation In Clang Is Available
[This is a cross-posting of a message posted in cfe-dev mailing list ( http://lists.cs.uiuc.edu/pipermail/cfe-dev/2013-August/031595.html); sorry for double-posting.] All, This is to announce availability of a full OpenMP 3.1 support implementation in Clang compiler. The project is hosted there: http://clang-omp.github.com/ 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. (Sorry, I can’t be more specific here, as properly reporting performance results is a precise and laborious process. You are welcome to try clang compiler with OpenMP support on your own OpenMP programs, awe performance gains and share excitement with the community. :-)) The project was started by Mahesha HS (then at AMD), who created initial patch. After that, it was carried out by several Intel engineers; Alexey Bataev did most of the coding. Hal Finkel, Dmitry Gribenko and Doug Gregor contributed a lot with code reviews. OpenMP in an evolving standard; thus, there is always something still left to be done, and your contributions (of any kind -- patches, code reviews, testing, bug reports) are very much welcome!
