[petsc-users] mat option producing error for stash

[Norihiro Watanabe]

Hi,

I would like to check if my program assembles a matrix without
generating stash. To help checking it, I wonder if there is a mat
option producing errors if entries destined for other processors are
added/set. I mean something like MAT_NEW_NONZERO_LOCATION_ERR for
stashing.


Best,
Nori
