	The previous benchmarks are not suitable for testing parallel computers, and the so-called Linpack's Highly Parallel Computing benchmark, or HPLinpack benchmark, was introduced. In HPLinpack the size n of the problem can be made as large as it is needed to optimize the performance results of the machine. Once again, 2/3n³ + 2n² will be taken as the operation count, with independence of the algorithm used. Use of the Strassen algorithm is not allowed because it distorts the real execution rate.
