Parallel iterative sparse solver #7

Open meyer-nils opened 2 weeks ago

meyer-nils commented 2 weeks ago

On CPU, the iterative sparse matrix solver is still operating not in parallel and thus slows down execution significantly.

The following backends could be used instead of scipy:

PETSc: Should be powerful, but it is not easy to install cross-platform. So this should be an optional backend and not default.
Trilinos: Probably even more complex to setup than PETSc.
Apple Accelerate wrapper: Platform specific and would need some custom Cython.
