Dear Jeff, thanks for the information.

I see, OpenMPI doesn't remap anything; this explains probably why my runtime
of my simulation varies sometimes between 30% for the same setup.

Open MPI currently has very limited cartesian support -- it actually doesn't
remap anything.
That being said, it is *very* easy to extend Open MPI's algorithms for
cartesian partitioning. As you probably already know, Open MPI is all about
its plugins -- finding and selecting a good set of plu
Dear OpenMPI list,
I am using a MPI-parallelized simulation program, with a
domain-decomposition in 6-Dimensions.
In order to improve the scalability of my program I would like to know
according to what preferences
is MPI distributing the ranks when using MPI_Cart_create( reorder allowed).
