+ 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 distributed version (MPI based).
