sorry for double-posting.]<br><br>All,<br><br></div>This is to announce availability of a full OpenMP 3.1 support implementation in Clang compiler.<br><div><br>The project is hosted there: <a href="http://clang-omp.github.com/" target="_blank">http://clang-omp.github.com/</a><br>
<br>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).<br><br>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. :-))<br>
<br>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.<br>
<br>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!<br><br>Yours,<br>Andrey Bokhanko<br>
