The LINPACK Benchmarks are a measure of a system's floating point computing power. Introduced by Jack Dongarra, they measure how fast a computer solves a dense n by n system of linear equations Ax = b, which is a common task in engineering.The latest version of these benchmarks is used to build the TOP500 list, ranking the world's most powerful supercomputers.The aim is to approximate how fast a computer will perform when solving real problems.
