A starting point for finding information about computer system performance, benchmark test results and benchmark source code.

A high quality "building block" routines for performing basic vector and matrix operations. Level 1 BLAS do vector-vector operations, Level 2 BLAS do matrix-vector operations, and Level 3 BLAS do matrix-matrix operations.

A collection of linear algebra routines with an improved interface which exploits Fortran 95 features such as assumed-shape arrays, optional arguments, and generic interfaces. Includes source code, documentation, and related papers.

A software library containing over 1400 general purpose mathematical and statistical routines written in Fortran 77.

A collection of Fortran solvers for the initial value problem for ordinary differential equation systems.

A packages for solving large sparse linear systems by iterative methods.

A portable FORTRAN emulation of CRAY SCILIB.

A subroutines for solving some types of algebraically explicit differential algebraic equations.

Multiple precision arithmetic.

This is Richard Brent's classic MP package, which was published as TOMS algorithm 524. Contains some features such as the Bernoulli numbers, which are not available in either Smith or Bailey's packages. Dates from 1981.
