Don't remember - but you can try with latest superlu_dist and see if the problem persists. [it has a bunch of fixes]
To try latest superlu_dist - you can use balay/update-superlu_dist_6.1.0/maint_no_merge [this branch is off maint - so to try with master - you can merge this with master] git checkout master git checkout -b test git merge origin/balay/update-superlu_dist_6.1.0/maint_no_merge Satish On Thu, 6 Dec 2018, Matthew Knepley via petsc-users wrote: > Satish, > > This is exactly the same method (pzgssvx) that had a problem before.
