augmentation_scaling |
Value of the scaling coefficient in front of the augmented system. This is only useful when a GKB algorithm is used. By default, there is no augmentation.
n_stored_directions |
Number of iterations to perform before restarting the solver. This quantity is useful when a GCR or FMGRES is used.
xtra_sles_param |
Set of parameters only used in some situations such as the need to solve approximately the A.x = 1 linear system (A is the (1,1)-block matrix). This is a complementary step in the approximation of the Schur complement.
By default, this is a copy of the block11_sles_param with less restrictive convergence criteria
