Mark, I'll try to get you some numbers on this. One quick question. Is it possible to use
-pc_ml_CoarsenScheme METIS I've tried, but I get an error message. *ML*WRN* This function has been compiled without the configure *ML*WRN* option --with-ml_metis *ML*WRN* I will put all the nodes in the same aggregate, this time... *ML*WRN* (file ./Coarsen/ml_agg_METIS.c, line 966) I'm about to build, and I didn't know if I'm missing an option that I need.
