Introduction

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 differential equations using iterative methods.
Installing Lis requires a C compiler. If you wish to use the Fortran interface, a Fortran compiler is needed, and the algebraic multigrid preconditioner requires a Fortran 90 compiler. For parallel computing environments, an OpenMP or MPI library is necessary. Lis supports both the Harwell-Boeing and Matrix Market formats for importing and exporting user data.
