Dear PETSc team, I just have a small and naive question about graph weights in Parmetis. When looking at mat/partition/impls/pmetis/pmetis.c, it seems that weight arrays (for vertices or edges) can be given to parmetis, however the wgtflag variable is always set to 0 from what I understand, which means that no weights are used in ParMETIS_V3_PartKway. So does this mean that the parmetis routine uses the weight arrays whenever they are not NULL, even if wgtflag is 0? I didn't try to use any weight yet, but will probably try it soon... Thank you for any help you can provide, francois pacull.
