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.
