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.

To install itsol, run the following command in macOS terminal (Applications->Utilities->Terminal)
sudo port install itsol
To see what files were installed by itsol, run:
port contents itsol
To later upgrade itsol, run:
sudo port selfupdate && sudo port upgrade itsol
