[dune-pdelab] Runtime Jump for Large YaspCube Grids

[Dominic Kempf]

Hello Dion,

to answer your question we need some information on the exact problem you
are using for this benchmark. Can you provide us the code? I will refrain
from any wild guesses that come to my mind before having seen the actual
problem.

Best,
Dominic
