Hi all, I would like to read the errata for passive target RMA on shared memory. The issue is #61: https://github.com/mpi-forum/mpi-issues/issues/61 PR and pdf are still missing, but the ticket shows the change very clear, and they should come soon. I hope that this is okay. Although the problem and solution is well known since Sep. 2016, this errate was not yet pushed into the standard. I hope that it will work now (still on Monday, Hawaiian time) for MPI-4.0.
