     "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 perform an LU decomposition with partial pivoting and
triangular system solves through forward and back substitution.  The library
also provides threshold-based ILU factorization preconditioners.")
