LINPACK
LINPACK is Fortran library for numerical linear algebra. It was written by Jack Dongarra, Jim Bunch, Cleve Moler, and Pete Stewart. Designed for use on supercomputers in the 1970s and early 1980s, has been largely superceded by LAPACK, which will run more efficiently on modern architectures.The LINPACK Benchmark is based on LINPACK. Introduced by Jack Dongarra, it measures how fast a computer solves dense system of linear equations, a common task in engineering. It is an important measure of a system's floating point computing power.
