US Once Again Boasts the World's Fastest Supercomputer (zdnet.com)

The US Department of Energy on Friday unveiled Summit, a supercomputer capable of performing 200 quadrillion calculations per second, or 200 petaflops. Its performance should put it at the top of the list of the world's fastest supercomputers, which is currently dominated by China. From a report (thanks to reader cb_abq for the tip): Summit, housed at the Oak Ridge National Laboratory (ORNL), was built for AI. IBM designed a new heterogeneous architecture for Summit, which combines IBM POWER9 CPUs with Nvidia GPUs. It has approximately 4,600 nodes, with six Nvidia Volta Tensor Core GPUs per node -- that's more than 27,000. The last US supercomputer to top the list of the world's fastest was Titan, in 2012. ORNL, which houses Titan as well, says Summit will deliver more than five times the computational performance of Titan's 18,688 nodes.

    This is kinda silly. The fastest supercomputer is going to be whomever has built the newest one. Moore's law is slowing down a tiny bit, but it's still going. Someone spending $100,000,000 on a supercomputer today is going to have a slower machine than someone building one for the same amount in a year's time.

    While I agree it is silly, the top 10 supercomputers are not in chronological order. Their commission dates and ranking are listed below. The top 5 newest supercomputers in this list are #1, 3, 4, 8, 9 in PFlops. Considering the 5 newest supercomputers average a rank of #5 and the 5 oldest supercomputers on the top 10 list have an average rank of #6, there is little correlation between age and computational power among the top machines. That has far more to do with what the machines were built to do and what budget they had, not the year they were built. Being newer does make your dollar stretch much further though.

    The supercomputers are measured using Linpack. This is a simple benchmark and can be done efficiently by large number of dumb cores in parallel. Though some workloads mimic Linpack, most workloads don't, so Linpack is not a good measure of supercomputer speed. Another benchmark which is gaining momentum nowadays is HPCG (see http://www.hpcg-benchmark.org/ ) which measures more broader performance and it shows quite a bit different picture. The top is still the 2011 K Computer. Some NEC computers which don't make in top500 are ranked in thirties. The Chinese computer is current top500 leader but it is ranked 5th on HPCG, even behind their own other computer which is 1/3rd the speed on Linpack.

    ? You don't seem to be the only one with this misconception. I see several posts below that echo you. Note that this supercomputer temporarily replaces a Chinese supercomputer at the top of the list that did not use American processors. So, prior to this one, the world leading supercomputer did not use American processors.

    Furthermore, this one is not an Intel or AMD machine. Still American companies, but each node in this one has 2 IBM Power9s and 6 NVIDIA V100 Voltas. In fact, the GPUs are the real compute power in most of the really big supercomputers these days and lots of them run NVIDIA GPUs.

    The Power9s appear to be made in Malta, NY, but the NVIDIA V100s, arguably the real compute power, are made by TSMC in Taiwan. This machine might be designed in America, but it appears to be mostly made in Taiwan.

    These processors are made to work together. The Power9 has native support for the NVIDIA's NVLink connections. The Power9's 16GB of HBM2 memory maintains cache coherency with the Voltas, essentially acting as an L3 cache for the Voltas.

    The core count in this system is mind-blowing. The Power9s are apparently the version with 24 cores each. So 24*2*4600 = 220,800 SMT4 cores. The Voltas are hard to quantify. Each Volta has 84 Streaming Multiprocessors (SMs). By that count, there are 84*6*4600 = 2,318,400 SMs. This is where the real supercomputing occurs. But each SM in turn contains 64 FP32 cores, 64 INT32 cores, 32 FP64 cores, 8 Tensor Cores, and 4 texture units. I'm not going to even bother doing the math. Suffice it to say that this machine has already broken the exaflop barrier in problems that didn't require FP64 precision.

    The transistor count is also astounding. The Voltas have 21.1 billion transistors each. The Power9s have 8 billion. ((21.1*6)+(8*2)) * 4600 = 655.96 trillion transistors just in terms of processors. We've come a long way since the Intel 4004's 2300 transistors less than 50 years ago.
