<h1>"OpenMP®" Support for the OpenMP language</h1>
|
|
<!--*********************************************************************-->
|
|
|
|
<p>The OpenMP subproject of LLVM is intended to contain all of the
|
|
components required to build an executing OpenMP program that are
|
|
outside the compiler itself. Support for OpenMP 3.1 in Clang is in the
|
|
process of being promoted into the Clang mainline, and can be
|
|
found at <a href="http://clang-omp.github.io/">OpenMP/Clang</a>.
|
|
</p>
|
|
|
|
<p>Here you can find the code for the runtime library against which
|
|
code compiled by the OpenMP/Clang compiler must be linked before it
|
|
can run. This code is also available
|
|
at <a href="http://openmprtl.org/">openmprtl.org</a>; we intend to
|
|
keep the different sites in sync.
|
|
</p>
|
|
|
|
<p>We are, however, still missing test code. Any contributions in
|
|
that area would be greatly appreciated!
|
|
</p>
|
|
|
|
<p>All of the code here is <a
|
|
href="http://llvm.org/docs/DeveloperPolicy.html#license">dual licensed</a>
|
|
under the MIT license and the UIUC License (a BSD-like license).
|

<!--=====================================================================-->
|
|
|
|
<ul>
|
|
<li>Correctness as defined by the
|
|
<a href="http://www.openmp.org/mp-documents/OpenMP3.1.pdf">OpenMP
|
|
3.1 standard (PDF)</a> now, and <a href="http://www.openmp.org/mp-documents/OpenMP4.0.0.pdf">OpenMP

|
4.0 standard (PDF)</a> in the future.</li>
|
|
<li>High performance.</li>
|
|
<li>ABI compatibility with <a href="http://gcc.gnu.org">Gcc</a> and
|
|
<a href="http://software.intel.com/en-us/intel-compilers">Intel's
|
|
existing OpenMP compilers.</a>
|
|
</li>
|
|
</ul>
|
|
|
|
<!--=====================================================================-->
|
|
<h2 id="why">Why have the runtime code here?</h2>
|
|
<!--=====================================================================-->
|
|
|
|
<p>It makes sense to have the runtime sources in the same place
|
|
(and with the same license) as the compiler.
|
|
</p>
|
|
|
|
<!--=====================================================================-->
|
|
<h2 id="requirements">Platform Support</h2>
|
|
<!--=====================================================================-->
|
|
|
|
<p>The OpenMP runtime is known to work on 32 and 64 bit X86
|
|
processors when compiled with either the Intel compiler or gcc, and also the Intel® Xeon Phi™ product family, when compiled with
|
|
the Intel compiler.
|
|
</p>
|
|
|
|
<p>A full OS compatibility matrix is in
|
|
<a href="README.txt">README.txt</a>
|
|
</p>
|
|
|
|
|
|
<!--=====================================================================-->
|
|
<h2 id="dir-structure">Status</h2>
|
|
<!--=====================================================================-->
|
|
|
|
<p>Currently the runtime is built with either gcc or icc. Obviously
|
|
it would also be good to build with Clang.
|
|
