[petsc-users] ParMetis error

[Smith, Barry F.]

  Mark,

    It may be best to try jumping to the latest PETSc 3.12. ParMETIS had some difficult issues with matrices we started to provide to it in the last year and the code to handle the problems may not be in 3.11

    If the problem persists in 3.12 then I would start with checking with valgrind.
