Software:

SuperLU -- Sequential and parallel libraries to solve unsymmetric sparse linear systems using LU factorization.
PDSLin -- Parallel Domain-decomposition, Schur complement based hybrid sparse linear solver.
XBLAS -- A reference implementation for the Extended and Mixed precision BLAS standard.
ARPREC -- A C++/F90 package for performing arbitrary precision arithmetic.
CLAPACK -- Full set of LAPACK in C.
ieee_except -- A set of condition estimation routines, which are faster than those in LAPACK, by utilizing floating-point exception handling. It contains routines to manipulate IEEE exception sticky flags.
