ITSOL is a library of iterative solvers for general sparse linear systems of equations. ITSOL can be viewed as an extension of the itsol module in SPARSKIT. It is written in C and offers a selection of recently developed preconditioners. The preconditioner suite includes: ILUK (ILU preconditioner with level of fill) ILUT (ILU preconditioner with threshold) ILUC (Crout version of ILUT) VBILUK (variable block preconditioner with level of fill - with automatic block detection) VBILUT (variable block preconditioner with threshold - with automatic block detection) ARMS (Algebraic Recursive Multilevel Solvers -- includes actually several methods - In particular the standard ARMS and the ddPQ version which uses nonsymmetric permutations). Note that ITSOL is a scalar package. You may find parallel implentations of some of the preconditioners listed above in pARMS .
