ITERATIVE SOLVERS

GMRES(30), PCG. Iteration stopped if

Iterative solver treated as failure, if a break down occured or more than steps were needed.





ORDERINGS

PQ (PP resp.), RCM, MMD, AMD, MeTiS node ND, + row/column scaling

Matrices also seperately preprocessed by maximum weight matching and tested





PRECONDITIONERS

  1. Inverse-based multilevel ILU (referred as ILUPACK)

  2. ILUTP

  3. IB-ILUC (single-level, inverse-based)
