MPI Forum, There is some debate over whether ticket #420 is a ticket 0 change or an errata. If it is the latter, then it will be read at the June meeting in Chicago. https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/420 It is a bug fix for one of the examples of the new neighbourhood collectives.
