Frontier, the HPE Cray exa-scale supercomputer operated by the Department of Energy (DoE) at Oak Ridge National Laboratory (ORNL), is still by far the fastest supercomputer on the planet, according to Top 500 Computers.

With a High Performance Linpack (HPL) benchmark score of 1.102 Exaflops per second, Frontier is the only exa-scale supercomputer that is three times faster than its closest competitor, Fugaku, at the RIKEN Center for Computational Science (R-CCS) in Kobe, Japan. , according to the top 500. One exaflop is a quintillion arithmetic operations or floating-point operations (flops) per second.

Frontier, an HPE Cray EX system, has 8,730,112 cores and combines 3rd generation AMD EPYC processors optimized for HPC and AI, with AMD Instinct 250X accelerators, and Slingshot-10.

Frontier earned the top 500 spot for the month in June, when it achieved the same performance of 1.1 exaflops. It features a theoretical peak of 2 exaflops and is 10 times more powerful than ORNL’s own peak system.

Frontier is also part of the Department of Energy’s Exacscale computing project. Inside are 74 HPE Cray EX supercomputer cabinets, which include more than 9,400 AMD-powered nodes and 90 miles of networking cable, according to ORNL. It also contains 37,000 GPUs.

As ORNL explainsModeling cancer cells, supernovae, coronavirus or the atomic structure of elements requires the 64-bit precision that typical supercomputers provide, while machine learning algorithms require less headroom, for example 32, 24 or 16-bit precision and can therefore take advantage of of graphics processing units.

Frontier’s Orion storage system holds 700 petabytes of data; Each cabinet weighs 8,000 pounds and the system is cooled by 6,000 gallons of water pumped every minute by four 350-horsepower pumps. The pumps can fill an Olympic-sized swimming pool in 30 minutes. “Frontier is the clear winner in the exascale race, and it will take a lot of work and innovation to bring it out of the top spot,” reads a Top 500 press release.

Europe’s fastest supercomputer, which is third in the top 500, is Finland’s upgraded LUMI system, also HPE Cray EX. It is installed at EuroHPC at CSC Data Center in Kajaani, Finland and has a performance of 309.1 Pflop/s.

As Top 500 notes, the European Joint Undertaking for High Performance Computing (EuroHPC JU) It is pooling European resources to develop large-scale Exascale supercomputers for processing big data.

The newcomer is the Leonardo, which has been installed at the EuroHPC site in Cineca, Italy. It’s a French-made Atos BullSequana XH2000 system with Xeon Platinum 8358 32C 2.6GHz as main processors, NVIDIA A100 SXM4 40GB as accelerators, and Quad-rail NVIDIA HDR100 Infiniband as interconnect. It achieved a Linpack performance of 174.7 Pflop/s.

Atos earlier this year Unveiling the XH300a more powerful system than the XH200 with CPUs, GPUs and accelerators from AMD, Intel and Nvidia, as well as microprocessor technology from French company The Silicon Pearl (SiPearl).

Old Summit, a system built by IBM, ranks fifth with a performance of 148.8 Pflop/s.

Sierra, Summit’s sister at Lawrence Livermore National Laboratory, California, is in sixth place with a score of 94.6 Pflop/s.

China’s fastest supercomputer, Sunway TaihuLight, was The best performing supercomputer in the world in 2017, but now it ranks seventh with a performance of 93 Pflops/s. Tianhe-2A (Milky Way-2A) was the second fastest way in 2017 but is now in 10th place with a performance of 61.4 Pflops/sec. they were Overshadowed Summit and Sierra in 2018.

While China’s fastest supercomputers have slipped in the HPL Top 500 rankings, China still dominates the top 500 alongside the United States. The United States has 126 machines in the top 500, while China has 162 in this ranking. However, the number of systems in China is down from 173 in the June 2022 ranking. Europe as a whole accounted for 131 machines in the top 500, up from 118 in June.
