Hello All,

For the upcoming December ‘21 MPI forum, I’d like to announce a reading for a proposed change for the MPI 4.1 standard to clarifythe error handler argument to MPI_Comm_create_from_group and MPI_Intercomm_create_from_groups.

See issue

https://github.com/mpi-forum/mpi-issues/issues/511

and associated pull request

https://github.com/mpi-forum/mpi-standard/pull/629

Thanks,

Howard
