  • Tomasz Lis (born 1966), Polish journalist and former TV anchor
  • 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.
