Linear algebra codes designed for sparse matrices.
  • BILUM Code by Yousef Saad and Jun Zhang to solve general sparse linear systems by using Krylov subspace methods preconditioned by some multi-level block ILU (BILUM) preconditioning techniques.
  • DarkStar Software Spinoff Includes a block-band matrix solver and a Fortran 90 makefile with corresponding dependency generator. By Udo Grabowski.
  • ITPACK Collection of Fortran 77 subroutines for solving large sparse linear systems by adaptive accelerated iterative algorithms.
  • MINRES: Sparse Symmetic Equations Solves sparse linear equations using a conjugate-gradient type method.
  • MUMPS: A Multifrontal Massively Parallel Sparse Direct Solver Fortran 90 package for solving linear systems of equations of the form A*x = b, where the matrix A is sparse and can be either unsymmetric, symmetric positive definite, or general symmetric. Released in the public domain. Includes documentation, related publications, and an FAQ.
  • NIST Fortran Sparse BLAS Provides computational kernels for fundamental sparse matrix operations.
  • NSPCG Fortran 77 subroutines for solving large sparse linear systems by adaptive accelerated iterative algorithms.
  • OptimQR The optimqr program will read a description of the sparsity pattern of some system matrix for system of linear equations. It will then apply heuristic branch and bound search to find a near-optimal ordering of the rows and columns of the system matrix. The ordering is written to disk. The codegen.pl program can then read the system ordering, and create a solver written in Fortran 77, that will solve the system using sparse QR factorization (using Givens rotations).
  • PROPACK Software by Rasmus Munk Larsen for large and sparse SVD calculations, with versions in Fortran and Matlab.
  • SMLIB Fortran 90 modules by Ernst Meese for the compressed sparse row (CSR) and the modified sparse row (MSR) data storage formats, a very general incomplete LU factorisation routine, the Krylov subspace solvers CGS, BiCGSTAB and GMRES.
  • SMMP Fortran 77 code for sparse matrix multiplication, transposition, and format conversion.
  • SVDPACK Comprised of four numerical (iterative) methods for computing the singular value decomposition (SVD) of large sparse matrices using double precision Fortran 77.
  • SYMMLQ: Sparse Symmetic Equations Solves a set of sparse, symmetric linear equations using a conjugate gradient type method.
  • Systems Optimization Laboratory Code for sparse linear equations (symmetric or general) and sparse least squares, and updating a dense square factorization L C = U.
  • Y12m Fortran 77 code that solves sparse systems of linear algebraic equations by Gaussian elimination.
