Dear all,

thanks to you all for your many feedback that we received for this proposal.

Based on that, I updated the issue #120

   MPI_Cart_weighted_create / Topology aware Cartesian communicators 

   https://github.com/mpi-forum/mpi-issues/issues/120

for reading at September Meeting 2019 in Zürich.

For a full pdf of the proposal with changebars, see

   
https://github.com/mpi-forum/mpi-issues/files/3512431/mpi32-report-topol-2019-08-17-annotated.pdf

The pull request is at
    https://github.com/mpi-forum/mpi-standard/pull/98

A portable and complete implementation together with documentation
can be found on the issue and also on our EuroMPI 2018 directory: 

   https://fs.hlrs.de/projects/par/mpi/EuroMPI2018-Cartesian/

There will be also a paper presentation at the EuroMPI conference.

Because I'm on travel next week with very limited email-access,
I send out this email very early and a bit uncoordinated - my apologies.

Best regards
Rolf
