ITerative SOLvers - devel

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 implementations of some of the preconditioners listed above in pARMS.

This package provides the itsol header files required to compile C/C++ programs that use ITSOL.
