Creates a persistent communication request for a collective operation or neighborhood collective operation.
As of Nov. 2018, the feature of persistent collective communication operations and persistent collective neighborhood communication operations is planned to be included in the next MPI Standard after MPI-3.1.
https://github.com/mpi-forum/mpi-issues/issues/25
Open MPI implements 2018 Draft Specification of the MPI standard shown in the following URL.
https://www.mpi-forum.org/docs/drafts/mpi-2018-draft-report.pdf
The interface may still change in the standard. Therefore the prefix MPIX_ is used instead of MPI_ for these request creation routines. To start, complete, and free the created request, usual MPI routines (MPI_Start etc.) can be used.
Future versions of Open MPI will switch to the MPI_ prefix and will not require the C header file mpi-ext.h, the Fortran modules mpi_ext and mpi_f08_ext, and the Fortran header file mpif-ext.h once the MPI Standard which includes this feature is published.
