Preconditioners with GMRES
Closed this issue · 2 comments

Somehow none of the available preconditioners of CUSP speeds up a GMRES
solution. Only diagonal preconditioner seems to be working, but it causes a
slow down. Smoothed aggregation preconditioner gives NANs after a number of
iterations. ainv preconditioner freezes.

It is possible to check whether CULA Sparse's GMRES solver can be used with
preconditioners or not. CULA Sparse's CG solver can now be used with the
Poisson solver. With slight modification its GMRES solver can be available for
the N-S solver.

Issues related to the old segragated solver are being closed as WONTFIX.
