SuperLU is a general purpose library for the direct solution of
|
|
large, sparse, nonsymmetric systems of linear equations on high
|
|
performance machines. The library is written in C and is callable
|
|
from either C or Fortran. The library routines will perform 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 is the multi-threaded version (POSIX threads or OpenMP).
