It was written in [[Fortran]] by [[Jack Dongarra]], Jim Bunch, [[Cleve Moler]], and Gilbert Stewart, and was intended for use on [[supercomputer]]s in the 1970s and early 1980s.<ref>

LINPACK makes use of the [[Basic Linear Algebra Subprograms|BLAS]] (Basic Linear Algebra Subprograms) libraries for performing basic vector and matrix operations.

The [[LINPACK benchmarks]] appeared initially as part of the LINPACK user's manual. The parallel LINPACK benchmark implementation called [[HPL (benchmark)|HPL]] (High Performance Linpack) is used to benchmark and rank supercomputers for the [[TOP500]] list.
