Hi All, I suggest we meet today to continue the discussion where we left off last time with syncing up the diagrams with the document at ???. Also, I opened an errata issue concerning MPI_Comm_create_from_group to hopefully be included in the 4.1 standard. See https://github.com/mpi-forum/mpi-issues/issues/511 Please feel free to update this issue. This came up when one of my interns was writing unit sessions tests and wasn’t sure whether or not we could use an MPI_INFO_NULL like argument here. I have a conflict which may get canceled, but if not, I will not be able to attend today.
