======
Lis (Library of Iterative Solvers for linear systems, pronounced [lis])
is a parallel software library for solving discretized 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 eigenvalue problems
* Parallel preconditioners for iterative methods
* Quadruple precision floating point operations
* Performance analysis
* Command-line interface to solvers and benchmarks
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 library is used. Both the Harwell-Boeing and Matrix
Market formats are supported to import and export user data.
See PDF files in directory doc for full description.
