These Are The 7 Most Powerful Computers Of All Time

Jakarta - Supercomputers have held a highly valued position in the technology space. They are used for many things, including climate modeling, disease research, and nuclear science.

They are also used to run complex simulations involving many variables in the universe. More recently, supercomputers have been used to track the spread and mutation of the coronavirus.

Supercomputers are often ranked in terms of the number of computations per second. This so-called TeraFLOPS is a unit of computing power equivalent to one trillion (10¹²) floating-point operations per second.

Here are the supercomputers that are claimed to be the most powerful so far

Fugaku

Processor: IBM POWER9 22C 3.1GHz

Peak performance: 125.712 TFlop/sec

This IBM-made supercomputer combines two types of processor chips. Namely IBM's Power 9 processor and Nvidia's Volta graphics processing unit. Nuclear weapons scientists use it in nuclear weapons simulations as a substitute for underground testing. It helps assess the performance of nuclear weapons systems as well as nuclear weapons science and engineering calculations.

Sunway TaihuLight

Location: National Supercomputer Center in Wuxi, China

Cores: 10.649.600

Memory: 1.310.720GB

Processor: Sunway SW26010 260C 1.45GHz

Peak Performance: 125.436 TFlop/sec

This Chinese supercomputer has 40.960 many-core 64-bit RISC SW26010 processors designed in China based on the Sunway architecture. Each processor chip contains 256 processing cores.

The name translates as divine power, the light of Taihu Lake. From June 2016 to June 2018, it was the fastest supercomputer in the world. Computers are involved in modeling climate, weather, and earth systems, life science research, advanced manufacturing, and data analytics.

Perlmutter

Location: National Energy Research Scientific Computing Center, USA

Cores: 706.304

Memory: 390.176GB

Processor: AMD EPYC 7763 64C 2.45GHz

Peak Performance: 89.794.5 TFlop/sec

This supercomputer is based on the HPE Cray “Shasta” platform and is a heterogeneous system with GPU-accelerated nodes and only a CPU. It was named in honor of Nobel prize winner Saul Perlmutter.

Among its use cases are nuclear fusion simulation, climate projection, and materials and biological research.

Selene

Location: NVIDIA Corporation, USA

Cores: 555.520

Memory: 1.120.000 GB

Processor: AMD EPYC 7742 64C 2.25GHz

Peak Performance: 79.215 TFlop/sec

Selene is a DGX SuperPOD powered by an Nvidia A100 GPU and an AMD Epyc Rome CPU in the DGX A100 form factor. Using Mellanox HDR InfiniBand as a system network.

The Selene platform supports a broad user community, such as supercomputer-scale continuous integration for software, research, "big iron AI" work (e.g., Megatron, ASR), and automotive.

Tianhe-2A

Location: National Supercomputer Center in Guangzhou, China

Cores: 4.981.760

Memory: 2.277.376 GB

Processor: Intel Xeon E5-2692v2 12C 2.2GHz

Peak Performance: 100.679 TFlop/sec

This supercomputer was developed by China's National Defense Technology University (NUDT) and is housed at the National Supercomputer Center in Guangzhou, China.

When first deployed, it had 16.000 computer nodes, each consisting of two Intel Ivy Bridge Xeon processors and three Xeon Phi coprocessor chips, one of the largest implementations of Ivy Bridge and Xeon Phi chips in the world.

It runs on Kylin Linux, a version of the operating system developed by China's National University of Defense Technology (NUDT).
