ITL uses the abstract interface of matrix-vector, vector-vector, and vector-scalor operations MTL is default to serve those operations. ITL is able to use other packages such as Blitz++ and BLAS with the same abstract interface provided.

The Iterative Template Library is:

Generic, Orthogonal, and Comprehensive:

ITL includes a large number of preconditioners and iterative methods. Users are able to use ITL with their data structures if those data structures need the concepts of algorithms.

Flexible and Extensible:

The ITL interface is designed to allow using other packages conforming to the abstract interface of matrix-vector operations. ITL is able to extend the matrix-free methods without any problems.

High Performance:

The performance of ITL is mainly dependent on the package provides matrix-vector operations. With the default MTL implemention ITL demonstrates performance equal to (and in many cases better than) other fine-tuned Fortran libraries.

Reliable:

ITL is extensively tested on a nightly basis.

Portable:

ITL is written in ANSI C++ and can be compiled and used on any target platform with an ANSI C++ compiler.

Current release of ITL is 4.0.0.

The mail list of ITL is combined in the MTL mail list. If you would like to be kept informed as new releases of ITL are made available, please subscribe to our MTL announcement list.
