An early benchmark for scientific applications, since replaced by System Performance Evaluation Cooperative (SPEC) benchmarks. See SPEC.

(n.) A linear algebra software package, which has been mounted on a wide range of platforms. It has now been superceded by LAPACK. (n.) also a set of widely quoted performance benchmarks based on linear algebra and available from the National Software Exchange.

LINPACK is a software library for performing numerical linear algebra on digital computers. It was written in Fortran by Jack Dongarra, Jim Bunch, Cleve Moler, and Pete Stewart. Designed for use on supercomputers in the 1970s and early 1980s, it has been largely superseded by LAPACK, which will run more efficiently on modern architectures.
