[SciPy-dev] petsc - UMFPACK and scipy

[Nils Wagner]

Ondrej,

Please can you show me an example where petsc solvers are "better" than
UMFPACK.

4) About the petsc - I know it's another dependence. However, I
noticed you are using umfpack in SciPy. So why not petsc? I think it
contains much more (sometimes better) solvers (depends on the
problem). It's seems logical to me, to either use nothing, or the best
library available, which I believe is petsc.
