[petsc-users] Avoid MUMPS ordering for distributed matrices?

[Dominik Szczerba]

In my procedure considerable time is spent to partition the domain.
When using MUMPS as a solver for my matrix I see the message:

"Ordering based on METIS"

and this seems to take a lot of time. Is it not possible to take over
the existing ordering, or is this ordering something else than matrix
partitioning that I had already performed?

Thanks for any clarifications,
Dominik
