The floating-point environment on Sun SPARC and
x86/x64 platforms enables you to develop robust, high-performance,
portable numerical applications. The floating-point environment can
also help investigate unusual behavior of numerical programs written by
others. These systems implement the arithmetic model specified by IEEE
Standard 754 for Binary Floating Point Arithmetic.
Sun Performance Library is a set of optimized,
high-speed mathematical subroutines for solving linear algebra and other
numerically intensive problems. Sun Performance Library is based on a
collection of public domain library functions available from Netlib
(http://www.netlib.org)
that have been enchanced and optimized for high-performance Sun platforms.
Sun Performance Library contains enhanced versions of the
following standard libraries:
- LAPACK version 3.1.1 for solving linear algebra
problems.
- BLAS1 (Basic Linear Algebra Subprograms)
for performing vector-vector operations.
- BLAS2 for performing matrix-vector
operations.
- BLAS3 for performing matrix-matrix
operations.
- Netlib Sparse-BLAS for performing
sparse vector operations.
- NIST Fortran Sparse BLAS version 0.5
for performing fundamental sparse matrix operations.
- SuperLU version 3.0
for solving sparse linear systems of equations.
Sun Performance Library includes the following additional
routines:
- Fast Fourier transform (FFT) routines
- Direct Sparse Solver routines
- Interval BLAS routines

Numerical Computation Guide
A complete application programmer's handbook to understanding the data
structures and operations made available by hardware, system software,
and software libraries that together implement IEEE Standard 754. IEEE
Standard 754 makes it easier to write numerical applications. It is a
solid, well-thought-out basis for computer arithmetic that advances the
art of numerical programming.
