(description " This version of Open@tie{}MPI has an implementation of
@code{MPI_Init_thread} that provides @code{MPI_THREAD_MULTIPLE}. This won't
work correctly with all transports (such as @code{openib}), and the
performance is generally worse than the vanilla @code{openmpi} package, which
only provides @code{MPI_THREAD_FUNNELED}.")))
