Minimal implementation/example for a MPI-enabled multigrid-preconditioned-solver

[rbourgeois33]

Hi,

The implementation examples such as multigrid-preconditioned-solver are very helpful for understanding how to use the ginkgo library.

I would like to test the performances of the library on our CFD matrices when solving linear systems on several GPUs.

Is there a sample code or a tutorial for this ?

Thanks in advance,
Rémi

Hi @rbourgeois33 , thanks for bringing this up.
Sure, I will create a sample code to demonstrate the distributed multigrid setup
