Top High-Performance Computers by TeraFLOPS

Die weltweit leistungsfähigsten Rechnersysteme werden als Supercomputer bezeichnet. Die meisten dieser digitalen Giganten finden ihren Einsatz in der Industrie. Hier berechnen sie u.a. komplexe Simulationen. Die Infografik von Statista zeigt die Rechenleistung der leistungsstärksten Supercomputer weltweit im November 2018. Der Rechner “Summit” vom Hersteller IBM erzielt eine Leistung von rund 143.500 TeraFLOPS (21,23 Billiarden FLOPS, oder 143 PetaFLOPS). FLOPS steht dabei für Floating Point Operations Per Second und bezeichnet die Anzahl der ausführbaren (Gleitkomma-) Rechenoperationen pro Sekunde. Zum Vergleich: laut Angaben von Sony erreicht die Grafikeinheit der Spielekonsole Playstation 4 eine Rechenleistung von 1,84 TeraFLOPS. Umgerechnet in Konsolen entspricht die Leistung von Summit also der von rund 78.000 Sony Playstation 4.

Als schnellstes deutsches Rechensystem ist der Rechner SuperMUC-NG erstmals unter die in der Grafik gezeigten weltweiten Top-10 eingezogen. Der deutsche Superrechner vom Hersteller Lenovo hat es dabei knapp verpasst, sich an die europäische Spitze zu setzen: Vor ihm liegt noch Piz Daint aus der Schweiz.

Die im Halbjahres-Rhythmus veröffentlichte Top-500-Liste der rechenstärksten Computer ist ein Indikator dafür, wo Forschung mit Big Data am intensivsten betrieben wird. Die meisten dieser Rechner stehen in China.

November 2018

The 52nd edition of the TOP500 list saw five US Department of Energy (DOE) supercomputers in the top 10 positions, with the first two captured by Summit at Oak Ridge National Laboratory (ORNL) and Sierra at Lawrence Livermore National Laboratory (LLNL).

Summit widened its lead as the number one system, improving its High Performance Linpack (HPL) performance from 122.3 to 143.5 petaflops since its debut on the previous list in June 2018. Sierra also added to its HPL result from six months ago, going from 71.6 to 94.6 petaflops, enough to bump it from the number three position to number two. Both are IBM-built supercomputers, powered by Power9 CPUs and NVIDIA V100 GPUs.

Sierra’s ascendance pushed China’s Sunway TaihuLight supercomputer, installed at the National Supercomputing Center in Wuxi, into third place. Prior to last June, it had held the top position on the TOP500 list for two years with its HPL performance of 93.0 petaflops. TaihuLight was developed by China’s National Research Center of Parallel Computer Engineering & Technology (NRCPC).

Tianhe-2A (Milky Way-2A), deployed at the National Supercomputer Center in Guangzho, China, is now in the number four position with a Linpack score of 61.4 petaflops. It was upgraded earlier this year by China’s National University of Defense Technology (NUDT), replacing the older Intel Xeon Phi accelerators with the proprietary Matrix-2000 chips.

At number five is Piz Daint, a Cray XC50 system installed at the Swiss National Supercomputing Centre (CSCS) in Lugano, Switzerland. At 21.2 petaflops, it maintains its standing as the most powerful system in Europe. It is powered by a combinations of Intel Xeon processors and NVIDIA Tesla P100 GPUs

Trinity a Cray XC40 system operated by Los Alamos National Laboratory and Sandia National Laboratories improved its performance to 20.2 petaflops, enough to move it up one position to the number six spot. It uses Intel Xeon Phi processors, the only top ten system to do so.

The AI Bridging Cloud Infrastructure (ABCI) installed in Japan at the National Institute of Advanced Industrial Science and Technology (AIST) is listed at number seven with a Linpack mark of 19.9 petaflops. The Fujitsu-built system is powered by Intel Xeon Gold processors, along with NVIDIA Tesla V100 GPUs.

Germany provided a new top ten entry with SuperMUC-NG, a Lenovo-built supercomputer installed at the Leibniz Supercomputing Centre (Leibniz-Rechenzentrum) in Garching, near Munich. With more than 311,040 Intel Xeon cores and an HPL performance of 19.5 petaflops, it captured the number eight position.

Titan, a Cray XK7 installed at the DOE’s Oak Ridge National Laboratory, and previously the most powerful supercomputer in the US, is now the number nine system. It achieved 17.6 petaflops using NVIDIA K20x GPU accelerators.

Sequoia, an IBM BlueGene/Q supercomputer installed at DOE’s Lawrence Livermore National Laboratory, is the 10th-ranked TOP500 system. It was first delivered in 2011, achieving 17.2 petaflops on HPL.
