Lisandro Dalcin has sent us a nice example of solving a sparse system with
a scipy.sparse matrix by petsc4py - let's interface petsc solvers.

The present use of `MatGetSubMatrix` looks awkward and like it wastes significant memory, particularly when there are several MPI processes per device. `MatGetSubMatrices` does more precisely what you…

It would be helpful to be able to test various types of nonlinear solvers at the macro scale. Various options such as PETSc/SNES, Trillinos/Nox/LOCA, and LLNL/Sundials are available. Each of these opt…
