Hi all, The Collective and Persistent WGs would like to read issue 90 (PR 51), Front matter material to address the addition of persistent collective communication operations; this impacts the Collective Chapter at present. (No new wording has been added to the Topology chapter or elsewhere in this set of changes as proposed.) Issue: <https://github.com/mpi-forum/mpi-issues/issues/> https://github.com/mpi-forum/mpi-issues/issues/90 PR: https://github.com/mpi-forum/mpi-standard/pull/51 PDF: https://github.com/mpi-forum/mpi-standard/files/2043453/mpi32-report-ticket9... This is a consequence of Issue #25 being accepted to the standard. This is not needed if Issue #25 is not voted in successfully. Thank you, Tony Skjellum
