Introduction

Lis, a Library of Iterative Solvers for linear systems, is a scalable parallel library for solving linear equations and eigenvalue problems with sparse iterative methods.
Installation of Lis requires a C compiler. To use the Fortran interface, a FORTRAN 77 compiler is required. To use the algebraic multigrid preconditioner, a Fortran 90 compiler is required. OpenMP and MPI-1 are used in parallel computing environments.
Lis has been tested on the following platforms:

• Version 1.2.15 (September 8, 2009) New!
  • lis-1.2.15.tar.gz (source code)
  • lis-manual-1.2.15_en.pdf (user's manual)
• Version 1.1.2 (September 24, 2007)
  • lis-1.1.2.tar.gz (source code)
  • lis-manual-1.1.2_en.pdf (user's manual)
  • lis-1.1.1-win32.zip (binary package for Windows)
