[petsc-users] Benchmarking different PETSc installations

[Barry Smith]

   We don't really have a good application included with PETSc for this purpose, our examples are too simple, implemented just to demonstrate specific ideas.  You might talk to Richard Mills who is at ORNL about using PFLOTRAN for this purpose.
