Hi together, 
I'm currently evaluating to use PETSc as framework for our next software project. 
My question concerns dynamic repartitioning: I have already found in the Documentation (Chapt. 3.5) that PETSC does not currently support dynamic repartitioning, load balancing by migrating matrix entries between processes, etc. I know that Zoltan e.g., which PETSC can be configured with offers this functionality. Is there an tutorial demonstrating how the automatic load-balancing features of Zoltan can be used in combination with linear/non-linear solvers offered by PETSC? Or should one, for problems requiring dynamic load-balancing strategies move to Trilinos all together?
Thank you for any input,
Best Regards, 
Alex von Ramm
