The K Computer is based at the RIKEN Advanced Institute for Computational Science in Kobe, Japan, and smashes the previous supercomputing records with a processing power of more than 8 petaflop/s (quadrillion calculations per second) — three times that of its nearest rival."

peace is not a static state of being. peace is a balanced state of tension between armed foes. war is a disruption in this equilibrium that is then restored. the goal of maintaining peace is to not have any sudden shocks to the status quo
you will never, ever, have a world where peace is simply a static state of being that requires no armed maintenance. why? human nature is why
show me a place where everyone is unarmed and peaceful, and i'll show you a warlord's pillaging grounds
sorry, but this is reality. stop asking for things that don't exist, and never will, as long as human beings are human beings

The K Computer was built by Fujitsu, and contains more than 80,000 2GHz SPARC64 VIIIfx CPUs, each with eight cores, to deliver a total of more than 640,000 processing cores.
That said I'm fairly surprised that it managed to be the 4th highest efficiency system, the SPARC64 isn't really known for being a hugely efficient and the low density of FLOPS/chip would normally mean it needs more support infrastructure further lowering the efficiency. Obviously the guys at Fujitsu have managed to do some great system engineering since Rmax is so close to Rpeak, kuddo's to them for making an awesome system around an ok chip!
