libsuperlu3 binary package in Ubuntu Trusty ppc64el

 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.
