Facebook builds the world's most powerful AI supercomputer

Meta, the company behind Facebook, said the supercomputer will be completed as soon as 2022, serving AI research to develop the metaverse.

The system, called AI Research SuperCluster (RSC), was declared by CEO Mark Zuckerberg of Meta as "the most powerful AI supercomputer in the world" when it was released later this year. The product is built for metaverse development in mind.

"Our experience shows that the metaverse will require enormous computing power with billions of billions of calculations per second. RSC enables a new AI model that can learn from trillions of samples, understand hundreds of languages and more. more," wrote Mark Zuckerberg.

In an article on the company's website, Meta's Technical Director Kevin Lee explains their need for increasingly high processing power in speech, language, and vision tasks. For example, to identify harmful content, the system needs to process longer videos, faster sampling rates, speech recognition must work well in situations with background noise, etc. .

In the field of metaverse, RSC is expected to create completely new AI systems. For example, it could provide voice translation for a group of people who speak a different language at the same time, allowing them to work together or play an AR game.

According to Mr. Lee, in the early stages, RSC is equipped with 760 Nvidia DGX A100 systems with 6,080 GPUs for computing tasks. This number will increase to 16,000 GPUs when completed. The GPUs communicate with each other via the Nvidia Quantum transmission system at 200 Gb/s. Triple-tier memory with capacities of 10, 46, and 175 petabytes, respectively.

In the test published by the company, the process of processing computer vision tasks is 20 times faster than the system that Meta is using with 22,000 Nvidia V100 Tensor Core GPUs.

As the most powerful AI supercomputer, Meta's RSC is not necessarily the most powerful supercomputer in the world. According to experts, it is necessary to distinguish between "supercomputer" and "AI supercomputer". RSC cannot be compared with machines used in fields such as cosmology, nuclear physics... because they have different purposes.

The difference between these supercomputers comes from the need for precision, said Bob Sorensen, a supercomputer analyst at Hyperion Research. Operations can occur between very large or very small numbers, including decimals. The precision of the numbers after the comma can be inversely proportional to the calculation speed. AI is a field that requires not too high precision, so Meta's supercomputer will probably have faster computing speeds than supercomputers in the rest of the fields.

In addition, according to Bob Sorensen, Meta's publication is based on theoretical calculations. In fact, most supercomputers won't be able to run with this performance.

Currently, the world's most powerful supercomputer belongs to the Fugaku machine, developed by Fujitsu and Japan's Riken National Research Institute with a computational speed of 442 petaflops, or 442 million billion operations per second. This is almost three times higher than the second-ranked supercomputer, IBM's Summit, with 148 petaflops. In third place is Sierra, the system located at Lawrence Livermore National Laboratory (USA) with a speed of 94.6 petaflops.

1968 Pontiac Firebird

1968 Pontiac Firebird photos collection, awesome Pontiac Firebird pictures The Pontiac Firebird is an American automobile that was built by Pontiac from the 1967 to the 2002 model years. The Firebird was introduced 23 February 1967, the same model year as the automaker's platform-sharing model, the Chevrolet Camaro. This coincided with the release of the 1967 Mercury Cougar, which shared its platform with another pony car, the Ford Mustang. The name "Firebird" was also previously used by Pontiac's parent company General Motors for the General Motors Firebird 1950s and early-1960s concept cars. First generation Firebirds (1967–1969) The first generation Firebirds had a characteristic Coke bottle styling. Unlike its cousin the Chevrolet Camaro, the Firebird's bumpers were integrated into the design of the front end. The Firebird's rear "slit" taillights were inspired by the Pontiac GTO. Both a two-door hardtop and a convertible were offered throug...

1967 Pontiac GTO

The Pontiac GTO is an American muscle car that was built by Pontiac in generations from 1964 to 1974 model years, and by GM's subsidiary Holden in Australia from 2004 to 2006. 1967 Pontiac GTO 1969 Pontiac GTO the "Judge" The first three generations of the Pontiac GTO was a muscle car of the 1960s and 1970s era.The Pontiac GTO was known as the judge of all muscle cars. the Pontiac GTO is considered by some to have started the trend with all four domestic automakers offering a variety of competing models. 1970 Pontiac GTO "Judge" For the 1964 and 1965 model years, the GTO was an optional package on the intermediate-sized Pontiac Tempest. The GTO became its own model from 1966 to 1971. It became an option package again for the 1972 and 1973 intermediate Le Mans. For 1974, the GTO option package was offered on the compact-sized Ventura. 1971 Pontiac GTO The GTO was selected Motor Trend Car of the Year in 1968.It was the only muscle car in the world which containe...

Greatest muscle cars of all time

Because it is a genre that enthusiasts are passionate about, you are bound to generate some criticism when compiling a list of the 7 greatest muscle cars of all time. However, we stuck its neck out to do just that. Some enthusiasts trace the history of muscle cars to the 1949 Oldsmobile Rocket 88. But the heyday of this genre ran from 1965 to 1970 before collapsing under the weight of higher gas prices, more stringent exhaust emissions regulations and soaring insurance costs. What is a muscle car? There isn't a settled definition, but most experts agree it's a smaller, 2-door car powered by a high-displacement engine typically found in a larger, full-size sedan. Some argue that pony cars, such as the Ford Mustang and Chevrolet Camaro, aren't muscle cars at all, but for this list, we chose not to make that distinction. Manufacturers engineered muscle cars for straight-line speed, inspiring more than an occasional Saturday night drag race between traffic lights. Neither built...

Netflix gets user reaction when blocking account sharing

Netflix to Make Changes for People Who are Sharing the Same Accounts A lot of users decided to cancel the service after Netflix no longer allowed account sharing in more than 100 countries. Every three months, Brandy Andersen loads her clothes, kitchen supplies, fans, and a small TV into her car to travel to a new city. Her job as an emergency nurse makes her travel frequently between New York, Boston and Washington, as well as remote parts of northern California. Meanwhile, her Netflix account is registered at her home address in the state of Georgia, thousands of kilometers away. Andersen is one of many longtime Netflix customers who are angered by the account sharing block, which began in place in the U.S. last week. After years of encouraging account sharing with each other, Netflix is asking users to set a location, like a subscriber's home address. When logging into an account at this location, anyone can use the account. If the user enters the account from another location, ...

Cortana will stop working on Windows

Hi! I'm Cortana The eight-year-old virtual assistant Cortana on Windows is about to stop working, after Microsoft launched a series of new AI applications. On its support page, Microsoft says it is "making changes to Windows that may affect Cortana users." By the end of 2023, this virtual assistant will no longer appear on its operating system as a standalone application. Cortana first appeared on the Windows Phone mobile operating system to compete with Google Assistant or Apple Siri. Microsoft later expanded the assistant to other platforms, including Android and iOS. Since 2015, Cortana has been deeply integrated into Windows 10 and the Microsoft product ecosystem, supporting users in tasks such as scheduling, tasks, and voice email. According to Microsoft, the change with Cortana will first affect apps in Windows. Other platforms such as Outlook mobile, Teams mobile will still use this virtual assistant. Cortana's death announcement comes after Micorosft introduce...
