[dune-pdelab] Accumulation mode for Nonoverlapping AMG

[Markus Blatt]

Hi,


is there a special reason (e.g. a bug), why the default accumulation
mode for the nonoverlapping AMG ist atOnceAccu (if accumulation
happens, everything is gathered on one process)? For the overlapping
case we allow the numbers of processes on the coarse level to decrease
to a smaller number of processes (>=1) and do this successfully.
