Name        : OpenNL
Product     : Fedora 15
Version     : 3.2.1
Release     : 5.fc15
URL         : http://alice.loria.fr/index.php/software/4-library/23-opennl.html
Summary     : A library for solving sparse linear systems
Description :
OpenNL (Open Numerical Library) is a library for solving sparse linear systems,
especially designed for the Computer Graphics community. The goal for OpenNL is
to be as small as possible, while offering the subset of functionalities
required by this application field. The Makefiles of OpenNL can generate a
single .c + .h file, very easy to integrate in other projects. The distribution
includes an implementation of our Least Squares Conformal Maps parameterization
method.

New version: OpenNL 3.2.1, includes support for CUDA and Fermi architecture
(Concurrent Number Cruncher and Nathan Bell's ELL formats)


OpenNL offers the following set of functionalities:

    Efficient sparse matrix data structure (for non-symmetric and symmetric
matrices)
    Iterative builder for sparse linear system
    Iterative builder for sparse least-squares problems
    Iterative solvers: conjugate gradient, BICGStab, GMRES
    Preconditionners: Jacobi, SSOR
    Iterative solver on the GPU (Concurrent Number Cruncher and Nathan Bell's
ELL)
    Sparse direct solvers: OpenNL can be linked with SuperLU
    Simple demo program with LSCM (Least Squares Conformal Maps)
