but are not onthat list. Most of the TOP500 machines reach more than 80% ofefficiency if they run LINPACK, on the other hand, if thesemachines run real engineering applications, they reachsignificantly less (~5%), due to the non-optimal manipulationwith matrices, or due to the need for execution of non-numericaloperations.A creator of the TOP500 supercomputers list rightfully claimedthe list sheds light on only one dimension of modernsupercomputing,
