Since 2013, Chinese machines have occupied the number one slot in rankings of the world's most powerful supercomputers. Now America is back on top again. Engineers at the US Department of Energy's Oak Ridge National Lab in Tennessee have just unveiled Summit, a supercomputer with enough processing power to surpass the current record holder, China's Sunway TaihuLight.

The new machine is capable, at peak performance, of 200 petaflops—200 million billion calculations a second. To put that in context, everyone on earth would have to do a calculation every second of every day for 305 days to crunch what the new machine can do in the blink of an eye. Summit is 60 percent faster than the TaihuLight and almost eight times as fast as a machine called Titan, which is also housed at Oak Ridge and held the US supercomputing speed record until Summit's arrival.

[...] Jack Wells of Oak Ridge says the experience of building Summit, which fills an area the size of two tennis courts and carries 4,000 gallons of water a minute through its cooling system to carry away about 13 megawatts of heat, will help inform work on exascale machines, which will require even more impressive infrastructure. Things like Summit's advanced memory management and the novel, high-bandwidth linkages that connect its chips will be essential for handling the vast amounts of data exascale machines will generate. Scientists at the national lab say they've already leveraged Summit's AI smarts to conduct what is effectively an exascale comparative genomics calculation. Thanks to these and other advances, Summit will help us reach even more impressive peaks of computing power.

    If it is mine, it is erotica.
    If it is *yours*, it is porn.
