Note: Having O(Petaflops) compressed in 1U gives us an exascale supercomputer when putting O(1000) nodes next to each other -- a typical size of a well-equipped university supercomputer center, not even a national one. So neglecting the price tags, exascale computers are now within reach. If this does not make you nevous, read the first sentences of https://en.wikipedia.org/wiki/Exascale_computing https://en.wikipedia.org/wiki/Exascale_computing: > Exascale computing would be considered as a significant achievement in computer engineering, for it is believed to be the order of processing power of the human brain at neural level (functional might be lower). It is, for instance, the target power of the Human Brain Project.
