I just implemented two new solvers in Petsc that make use of
Krylov subspace recycling, which means that if you have to solve
a sequence of linear systems, the overall cost can be reduced
significantly (by 10 to 100).
Have you sent these to [email protected]? We would be happy to add
them.
Why is a special interface needed from libmesh?
Just to enable/disable the recycling, I'd assume? Our LinearSolver
doesn't know a priori how related each solve is to the previous.
