[Dune] experience with Dune/ALUGrid/Simplex on > 1000 cores

[Benedikt Oswald]

Dear Dune,

we are currently testing our code in a Cray XT5 environment.
In particular, we would like to scale to considerably more than 1000 cores
using ALUGrid<Simplex>, i.e. with unstructured tetrahedral grids.

Is there any experience with this out there ? In particular, do you think that
Metis/Parmetis could pose problems with this number of cores ?

Thanks for some hints and have a great day! Benedikt
