Is there an easy way to change these options? From MATSOLVERPASTIX,
it seems that no command line options to control this.

Do I have to modify PaStiX.py and recompile? If yes, would you like to
give me some hints
Looks like Pastix is running with different options hence different
performance.

Hello PETSc team,
I was using PaStiX within petsc 3.1-p8. Today, I am trying PaStiX
within petsc-dev. However, For the same code, solving the same linear
system takes longer time (120s vs 90s) in petsc-dev. Both are compiled
with debugging mode off. Is it possible that the newer PaStiX is
slower t
