[petsc-users] parmetis weights

[francois pacull]

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.
