[petsc-users] ParMETIS_V3_PartGeomKway

Hi guys, I'm wondering if there is any implementation for ParMETIS_V3_PartGeomKway()? All I can find is the implementation for ParMETIS_V3_PartKway and I'm wondering if including the vertex positions could help me get a better partitioning? Also I have a general question. Is minimizing number of edge cuts essentially the same as minimizing communication? I understand that they are related, but communication is proportional to the number of ghost points which is not exactly equal (its actually less than) to the number of edge cuts. So then is it possible that this could actually result in larger number of ghost points, at least for some of processors? Thanks, Mohammad
