exaflopTen Exascale supercomputers by 2023

The US is spending $1.8 billion on three exascale supercomputers which should be completed in 2021-2022. The US is building the A21 at Argonne national labs, Frontier at Oak Ridge national lab and El Capitan at Livermore national lab. By …

exaflopMost powerful supercomputer in Texas by 2019 with new cooling technology

A 250 petaflop supercomputer immersed in liquid coolant is being built in Texas. In 2019, it could be the world’s most powerful supercomputer. 40,000 server immersed in coolant are going into a data center in Houston. It is being built …

artificial intelligencePossible game changer in detection of submarines

China will try to use lasers, microwave radar and a lot of computation to detect submarines down to 500-meter depth. Experiments carried out by the United States and former Soviet Union achieved maximum detection depths of less than 100 meters, …

chinaChina is testing two prototype candidates for exascale supercomputers

China on Sunday put into operation a prototype supercomputer that will test out possible technologies and architectures for an exaFLOP supercomputer in 2020 or 2021. The Sunway exascale computer prototype was developed by the National Research Center of Parallel Computer …

computersMemristor based equation solver could cut energy used by 100 times for longer lasting smartphones

Up until now small variations in the current passing through a memristor device was not precise enough for numerical calculations. The Nanoelectronics group, University of Michigan, got around this problem by digitizing the current outputs—defining current ranges as specific bit …

futureLenovo made about 25% of the top500 supercomputers

In June, 2018, 117 of the 500 most powerful supercomputers included in the TOP500 are Lenovo installations. Nearly one out of every four systems (23.4 percent) on the prestigious list is a Lenovo solution. Most are built with 4 terabyte …

gpuRace for ExaFlop Supercomputers with GPU dominant machines

The World of supercomputers is shifting rapidly with most of the compute power coming from GPU acceleration. In June 2018, 56 percent of the additional flops were a result of NVIDIA Tesla GPUs running in new supercomputers. Most of the …

brontoflopsNon-von Neumann zettaFLOPS supercomputers, yottaFLOPS cryogenic supercomputers and beyond with molecular nanotechnology

Thomas Sterling has retracted his prediction that we will never reach ZettaFLOP computers. He now predicts zettaFLOPS can be achieved in less than 10 years if innovations in non-von Neumann architecture can be scaled. With a change to cryogenic technologies, …

computersNew silicon photonics will cut data center power by up to 50% and increase supercomputer speed

New optical modulators (the device that encodes digital information onto a light signal) use 100 times less energy than commercial modulators and the research modulators are only 5% of the size of the commercial devices. The new on chip photonic …

exaflopGerman university getting multi-petaflop Cray CS500 supercomputer

Paderborn University (Germany) has selected a Cray CS500 cluster accelerated by FPGAs as the first phase of its Noctua multi-petaflop supercomputer. The new supercomputer will be comprised of 272 compute nodes, connected by Intel’s 100 Gbps Omni-Path fabric. Each node …
