Implementations [Legacy]

**** The following is a legacy wiki entry inherited from the previous Google code repo; it is very likely out of date ****

If you have a library which supports Portals 4 and is not listed, please let us know.

Implementations

Open MPI

• You'll need either a checkout of the SVN trunk or a nightly tarball:

svn co https://svn.open-mpi.org/svn/ompi/trunk
cd trunk
./autogen.sh

OR

http://www.open-mpi.org/nightly/trunk/

• Then configure Open MPI:

   ./configure --prefix=<PREFIX> \
      --with-portals4=<PORTALS4> \
      --with-platform=contrib/platform/snl/portals4-orte
   make all install

The implementation is still a work in progress and likely to die in strange ways. The one-sided and collective algorithms have not been optimized for Portals 4 at this time.

Portals SHMEM

• An implementation of the OpenSHMEM specification over Portals 4 is available on [Google Code].
