The power of supercomputers
Before starting the list, it is important to explain how the capacities of these machines are measured to determine which ones are the most powerful. Power is measured in two values, Rmax and Rpeak, that is, respectively, the highest points scored LINPack bench bench, and a high theoretical point to be obtained by estimating those perfect conditions.
In both cases, the data are measured foldFLOPS (PFLOPS). FLOP means «floating point operations per second », or floating point performance per second. To get an idea of the mass, PC graphics cards measure their power in TFLOPS, and only handle much more powerful than 10 TFLOPS. Supercomputers measure their strength in PFLOPS, that is, if TFLOP is 1012 FLOPS, PFLOP is 1015 HISTORY
An IBM conference
This supercomputer is located in Oak Ridge's laboratory across the United States, and is the world's largest, with Rmax 148,600 and Rpeak of 200,795 PFLOPS. Its model is the IBM Power System AC922, and it equips POWER9 processors from IBM and Tesla V100 from NVIDIA.
IBM has seen it
This other IBM model is built by the IBM Power System S922LC series linked to the infiniband EDR, and features 94,640 Rmax and 125,712 Rpeak. Like Summit, it is equipped with IBM POWER9 and NVIDIA Tesla V100 processors. It is available from Lawrence Livermore's national laboratory, also at EUUU.
NRCPC Sunway TaihuLight
The third most powerful supercomputer in the world is located at the world center of Wuxi, China, and is capable of delivering up to 93,015 Rmax PFLOPS and Rpeak & # 39; s 125,436 PFLOPS. It is a farm of Sunway MPP models produced by Sunway, and is equipped with SW26010 processors that each have 260 physical cores.
NUDT & # 39; s Tianhe-2A
Another is a Chinese supercomputer, but this time it is located at Guangzhou's national parking center. It is also a TH-IVB-FEP server farm connected to TH Express-2, and is equipped with Intel Xeon E5-2692 v2 processors (12 cores and 24 processors) and Matrix-2000 (128 cores). Its capacity is 61,445 and 100,679 PFLOPS in Rmax and Rpeak respectively.
Dell EMC Border
This server farm is located in a computer center in Texas, United States, and is the only one dedicated to education and the only one that uses Linux CentOS as an operating system. It has Dell C6420 servers connected to the infiniband HDR and has Xeon Platinum 8280 processors, delivering power of 23,516 Rmax and 38746 Rpeak. As you can see, power numbers are already reduced gradually.
Piz Daint, of Crocus
This supercomputer is located at the Swiss National Supercomputing Center, Switzerland, and is the most powerful in Europe. It is built by Cray XC50 servers equipped with Xeon E5-2690 v3 processors and NVIDIA Tesla P100 graphics, delivering up to 21,230 PFLOPS Rmax and 27,154 PFLOPS Rpeak power supplies.
The Third Crusade
Although from the same manufacturer, this supercomputer is available at the Los Alamos national laboratory in the United States. It's similar to the interior but somehow inferior, since its Cray XC40 servers have Xeon E5-2698 v3 processors but Xeon Phi 7250 accelerators, and provide performance of 20,159 and 41,461 PLOPS to Rmax and Rpeak respectively.
AI Bridging cloud infrastructure, from Fujitsu
This supercomputer is located at the national center of advanced and advanced computer science in Japan. It features PRIMERGY CX2550 M4 servers equipped with Xeon Gold 6148 processors and Tesla V100 high-speed graphics, linked to infiniband EDR, and delivered up to 19,880 PFLOPS Rmax and 32,577 PFLOPS Rpeak performance.
This ThinkSystem SD530 server server connected to Intel Omni-Path is located in Leibniz, Germany, and includes Xeon Platin 8174 monitors that provide 19,477 and 26,874 PFLOPS performance in Rmax and Rpeak respectively.
We arrived at the world's 10th most powerful supercomputer with another IBM. In this case, the IBM Power System S922LC servers only use Sierra but at a lower rate. The processors used are also the IBM POWER9 and NVIDIA Tesla V100, but they are much smaller and the power they offer is up to 18,200 PFLOPS in Rmax and 23,047 PFLOPS in Rpeak. It is located in Lawrence Livermore's national legal laboratory in the United States, such as Sierra.
