We don´t have this. But it could be a useful utitilty.

We have something like this here:

  bench/fem/assembly

I created a little Python module that does runs various solver/preconditioner combinations.
It works by overwriting and extending the dolfin.solve routine.
The source and an example can be downloaded at:

Nice. Can you post some results (tables or plots)? It would be
interesting to see some numbers.

Post the numbers to the DOLFIN mailing list.
