Hello, I was wondering if it is already possible to set the number of levels with the ML package. I tried -pc_mg_levels and PCMGSetLevels, both do not work.
I have an 8*10^6 Poisson matrix, and so far ML has given me the best results. However, I think with increasing the gridsize, i should also increase the number of multigrid levels. What are your thoughts?
