The National Oceanic and Atmospheric Administration (NOAA) announced back in 2020 that it would be replacing some of its older, now-outdated supercomputers that are used to run weather forecasts and predict patterns. NOAA has now replaced the older models, which were Cry and IBM supercomputers located in Reston, Virginia, Florida, and Orlando - with two Hewlett Packard Enterprise (HPE) Cray supercomputers.

These two supercomputers come with 2,560 AMD Epyc Rome 64-core 7742 server CPUs that collectively provide 327,680 cores that are capable of operating up to 12.1 petaflops. This new setup is approximately three times faster than what NOAA was previously using, and with the new upgraded power, the agency believes it will be able to provide more accurate and detailed weather forecasts to the public. Notably, the two new NOAA supercomputer systems are called Dogwood and Cactus, and rank as the 49th and 50th fastest supercomputers in the world.

According to the researchers behind the latest Sunway supercomputer, the Sunway has over 37 million CPU cores, quadrupling the number found in Frontier, nine petabytes of memory, and 96,000 semi-independent computer systems referred to as 'nodes,' that can exchange data at rates greater than 23 petabytes per second. The Sunway is capable of exascale computing, allegedly up to 5.3 exaFLOPS (5.3 quintillion floating-point operations per second).

The research team trained an artificial intelligence (AI) model, named bagualu (meaning alchemist's pot), with 174 trillion parameters using the Sunway. According to the South China Morning Post, this number rivals that of the number of synapses in the human brain, though some estimates of the true number of synapses go as high as 1,000 trillion.

NVIDIA announced last week that Taiwan tech giants were preparing NVIDIA Grace CPU-powered servers, and now we have our first: the new Venado supercomputer that's being constructed by the Los Alamos National Laboratory. The new VENDAO supercomputer is capable of a huge 10 exaflops of peak AI performance.

It feels like a little bit of "me too" with NVIDIA's announcement of the Venado supercomputer, but more concrete details will be provided at the International Supercomputing Conference in Hamburg, Germany later today.

Quantum computing could unlock 190% leap in ray tracing performance

Anthony Garreffa | May 25, 2022 10:08 AM CDT

We all know that turning ray tracing on radically reduces performance, so any help in the performance department is not only welcomed, it's begged for.

Quantum computing could unlock 190% leap in ray tracing performance 01 | TweakTown.com

A team of researchers from the UK, US, and Portugal have suggested that there's some huge untapped performance using a hybrid of classical ray tracing algorithms with quantum computing. Ray tracing workloads that were boosted by up to 190% by quantum computing.

How? By limiting the amount of computations needed by each individual ray. The researchers demonstrated this by rendering a small, 128x128 ray traced image in three approaches: classical rendering, non-optimized quantum rendering, and optimized quantum rendering.
