Nevertheless, the LINPACK benchmark performance can provide a good correction over the peak performance provided by the manufacturer.
It is a simplification, since no single computational task can reflect the overall performance of a computer system. The aim is to approximate how fast a computer will perform when solving real problems. The latest version of these benchmarks is used to build the TOP500 list, ranking the world's most powerful supercomputers. 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 LINPACK Benchmarks are a measure of a system's floating-point computing power.
