【 摘 要 】

These are slides from a presentation during an NERSC site visit to Los Alamos National Laboratory. The following topics are covered: building/installing libfabric, OpenMPI using libfabric, MPICH using libfabric, Open SHMEM (Sandia), other applications, and what is next. The next steps are: get a libfabric 1.4 out, it would be nice to have libfabric 1.4 installed in system space on Cori, add libfabric modules on Cori, might be a good idea to have a SLURM PMI module to simplify its use when building/using Open MPI and MPICH built to use libfabric, and upgrade Edison to CLE 5.2 UP04 or newer.
