US Overtakes China in Top Supercomputer List (bbc.com) 74

China has been pushed into third place on a list of the world's most powerful supercomputers. From a report: The latest list by Top 500, published twice a year, puts two US machines -- Summit and Sierra -- in the top two places. The US has five entries in the top 10, with other entries from Switzerland, Germany and Japan. However, overall China has 227 machines in the top 500, while the US has 109. Summit can process 200,000 trillion calculations per second. Both Summit and Sierra were built by the tech giant IBM. China's Sunway TaihuLight supercomputer, which this time last year was the world's most powerful machine, is now ranked at number three, while the country also has the fourth spot in the list.

    ... to see a good smattering of non-intel CPUs make a good show again. Still waiting on the workstations based on those though. POWER9 is pretty much the only one you can also stuff in a one or two socket deskside box.

    American computers operate with numbers in binary format, strings of 1s and 0s, the optimal format for electronic computation.

    Chinese computers operate on primitive pictographs, little pictures like Egyptian hieroglyphics to represent objects. That is why a Chinese keyboard has over 1000 keys. They need a special key for every pictograph. It's a very primitive system rooted in the Neolithic era.

      China uses standard QWERTY keyboards. They enter hanzi using Pinyin [wikipedia.org], a phonetic script using the Latin alphabet.

      Keyboards with over a thousand keys were made decades ago, but they were for manual typing (keystroke directly to paper), and nobody uses them anymore. I have only seen them in museums.

    The TOP500 list is interesting, but people treating it like a "race" for the fastest machine is kind of silly.

    It used to be whomever could come up with the most optimal architecture would have the fastest computer. You had exotic CPUs running in custom hyper-ring or torus buses.

    Nowadays it's whomever throws the most amount of money at buying the newest and, generally, commodity hardware. There are different flavors of custom Linux micro-oses they run. There are different interconnects, though they are almos

    Even though #1 [top500.org] & #2 [top500.org] on the TOP500 are NVIDIA based. And NVIDIA DGX-1 lets anyone join TOP500 by buying a few dozens boxes and networking them together (see #50 [top500.org] and #51 [top500.org])

    The first thing through my head was, does it matter how fast it is if you don't know how to use it, the second was that comes with terrible innuendo...

    Regardless, what are really being done with the computers of value? Is the fastest supercomputer really adding the most value to the world?

    We're talking about the list of *known* supercomputers. I'm sure various government agencies have supercomputers that are secret. In fact, it's highly probable that the most powerful in the world are not public knowledge.

      Yes, absolutely. The Top-500 doesn't include systems from NSA and other US/non-US governmental agencies; corporate systems such as for oil exploration, etc.; or even some academic systems such as Blue Waters at UIUC.

      The Top-500 list is mainly for governmental bragging rights, as even the non-government owned machines are largely government funded. However, this list does help to push forward the research for tackling the big problems of scalable cost, performance, power, reliability, and programmability.

      • Petroleum Geo-Services (PGS) in Houston is actually on the list at #41 with 4 petaflops, but right next door is British Petroleum's cluster which I don't see on the list. This says it's 9 petaflops [bp.com] which would put it around #20. Shell also has some large clusters here.. I think around the astrodome area. Exxon has at least one Cray up north in the Woodlands which I don't see on the list either.
  • Basically you can simulate weather, nuclear bombs and a few other things, but that is it.

      Right. And in silico drug design and functional materials design do not exist. Those rotor blades and aeroplane wings also just simulate themselves.

        Well their parents better tell them to knock it off, I hear it will make you go blind.
