Comment (by knarf):

 I agree with Roland: we need more information to see what is going on.
 Especially, we need to know how exactly you run the par files (the exact
 command you used, and ideally also the content of the environment variable
 OMP_NUM_THREADS). Also, it would be good to know where in the simulation
 you see only 200%: is it during evolution or while still setting up
 initial data?
