| Description: |
SuperLU is a general purpose library for the direct solution of large,
sparse, nonsymmetric systems of linear equations. The library is
written in C and is callable from either C or Fortran program. It
uses MPI, OpenMP and CUDA to support various forms of parallelism. It
supports both real and complex datatypes, both single and double
precision, and 64-bit integer indexing. The library routines performs
an LU decomposition with partial pivoting and triangular system solves
through forward and back substitution. The LU factorization routines
can handle non-square matrices but the triangular solves are performed
only for square matrices. The matrix columns may be preordered
(before factorization) either through library or user supplied
routines. This preordering for sparsity is completely separate from
the factorization. Working precision iterative refinement subroutines
are provided for improved backward stability. Routines are also
provided to equilibrate the system, estimate the condition number,
calculate the relative backward error, and estimate error bounds for
the refined solutions.
This version uses MPI and OpenMP.
This is the mpich version. |
