[petsc-dev] corrupted ta->count with GAMG

Thu Oct 25 11:37:37 CDT 2012

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.

John
