Lis (linear algebra library)

Lis (Library of Iterative Solvers for linear systems, pronounced [lis]) is a scalable parallel software library for solving linear equations and eigenvalue problems that arise in the numerical solution of partial differential equations using iterative methods.

Features

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

Quadruple precision floating point operations

Performance analysis

Command-line interface to solvers and benchmarks

Example

A C program to solve the linear equation Ax=b is written as follows:

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 MPI library is used. Both the Harwell-Boeing and Matrix Market formats are supported to import and export user data.
