US Once Again Boasts the World's Fastest Supercomputer (zdnet.com) 85
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.

? 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

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 wha

But he said if they spent the same amount next year it would be faster, which is true. We don't know the prices of the machines you listed.

Not necessarily. IBM is also building a newer . . . slower . . . supercomputer for the DoE:
Summit is one of two of these next-generation supercomputers that IBM is building for the DEO. The second one is Sierra, which will be housed at the Lawrence Livermore National Laboratory. Sierra, which is also scheduled to go online this year, is less powerful at an expected 125 petaflops, but both systems are significantly more powerful than any other machine in the DoE’s arsenal right now.

Supercomputers these days are superscalar, so you can add as many racks and shelves of nodes as you have space and money for. When they do upgrades, they just swap out the old slowest nodes and add new nodes with the faster CPUs and GPU's.

I'd rent it out. Sell processing time on it. How else would one pay the power bills? You can rent a lot of processing power on Amazon, but you can't rent a supercomputer-grade high performance interconnect between your nodes. Not from them, anyway.
I'd offer a special service for non-profit customers: They can pay power costs only, but then they only get to use idle resources. Commercial-rate customers take priority - got to pay the bills somehow.

The bandwidth in Amazon's HPC nodes is sort of ok compared to some cluster configurations, but the latency still leaves a fair bit to be desired. Last I tested, 6 months ago, the AWS HPC networking still had a 6 times higher latency on real world tasks I tested it with, compared to Infiniband equipped nodes(depending on the node hardware in question, GPU's might even talk over Infiniband to another GPU inside the node, if it's on another PCIe root complex, because it's faster, and I didn't receive an answer

I am shocked that these firms don't yet offer to bill by CPU usage. I come from the end of the age when CPU cycles were charged per contract and were planned using budgets. It wasn't for rationing but to help pay for the resources.

How is this any different than a data center of the same scale? I'm not even sure it has a higher bisection bandwidth.
Okay—I am sure it will have way lower latency between nodes at any equivalent bandwidth tier. But unless you're planning to aggressively exploit that, it's just your garden variety datacenter make more expensive and less flexible.

High speed interconnects, and much more computing power, mostly in the GPUs that many headless data center servers don't even have.

There are plenty of critical applications that benefit from fast interconnects.

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/ [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
