lis(3) Introduction to Library Functions lis(3) NAME lis - library of iterative solvers for linear systems SYNOPSIS [see Lis User Guide for full description] DESCRIPTION Lis (Library of Iterative Solvers for linear systems, pronounced [lis]) is a parallel software library to solve discretized linear equations and eigenvalue problems that arise from the numerical solution of partial dif- ferential 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 eigenvalue problems * Parallel preconditioners for iterative methods * Quadruple precision floating point operations * Performance analysis * Command-line interface to solvers and benchmarks SYSTEM REQUIREMENTS Installing Lis requires a C compiler. If you wish to use the Fortran inter- face, a Fortran compiler is needed, and the algebraic multigrid precondi- tioner requires a Fortran 90 compiler. For parallel computing environments, an OpenMP or an MPI library is necessary. Lis supports both the Harwell- Boeing and Matrix Market formats for importing and exporting user data.
