Name

lis - library of iterative solvers for linear systems

Synopsis

[see Lis User Manual for full description]

Description

Lis, a Library of Iterative Solvers for linear systems, is a parallel library for solving linear equations and eigenvalue problems that arise in the numerical solution of partial differential equations using iterative methods.

Lis provides facilities for:

* Automatic program configuration

* NUMA aware hybrid implementation with MPI and OpenMP

* Exchangeable dense and sparse matrix storage formats

* Basic linear algebra operations for dense and sparse matrices

* Parallel iterative methods for linear equations and standard eigenvalue problems

* Parallel preconditioners for iterative methods

* Hardware accelerated internal quadruple (double-double) precision floating point operations

* Performance analysis

* Command-line interface to solvers

System Requirements

The installation of Lis requires a C compiler. The Fortran interface requires a Fortran compiler, and the algebraic multigrid preconditioner requires a Fortran 90 compiler. For parallel computing environments, an OpenMP or an MPI-1 library is used. Both the Harwell-Boeing and Matrix Market formats are supported to import and export user data.
