    devel/lwgrp: New port: Light-weight group library for MPI

    The Light-weight Group library provides data structures and collectives to
    create/destroy ordered process groups efficiently in MPI codes — useful
when
    frequent, transient groups make communicator creation too costly.

    https://github.com/llnl/lwgrp/

    It is one of the dependencies for sysutils/mpifileutils.
