    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.
