Uncle Sam bungs rich tech giants quarter of a billion bucks for exascale super R&D

Carrot dangled for 2021 mega-machines


The US government has dangled $258m in funding in front of six American tech giants to encourage the development of exascale supercomputer systems.

Uncle Sam wants at least one exascale machine powered up on American soil by 2021, and in production by 2022. A second system should also be arriving around that time, ideally.

By exascale, we mean a computer that can hit at least one exa-FLOPS, or a billion billion floating-point math calculations per second, which would smoke today's publicly known world's-fastest machine (China's 93PFLOPS Sunway TaihuLight). The US Department of Energy wants number-crunching beasts that can sustain exascale levels of performance for applications, rather than a peak 1EFLOPS figure that isn't achievable outside of a benchmark.

To help make this all happen, the Rick Perry-led energy department is offering about quarter of a billion dollars over a three-year period to half a dozen technology suppliers to carry out exascale R&D work. The companies will spend some of their own dosh on the effort – at least 40 per cent of the total research bill – ensuring taxpayers aren't footing the entire expense.

The plan, we're told by officials, is this: the tech giants will be paid to investigate specific areas of research, such as an application or system design, with input from supercomputing software developers and engineers. They'll be expected to produce final reports on each of the studies. The overall goal is to work out a way to build and supply affordable exascale machines that meet US boffins' requirements. Universities and government research labs will ultimately buy and operate the systems when they are ready using their own budgets.

"It isn't that we send the money, wait three years, and get an answer," said Paul Messina, director of the energy department's Exascale Computing Project. "The funding is based on specific work packages."

The six companies are: AMD, Cray, HPE, IBM, Intel and Nvidia. They will, according to Messina, be expected to come up with "innovative memory architectures, higher-speed interconnects, improved reliability systems, and approaches for increasing computing power without prohibitive increases in energy demand."

"It is essential that private industry play a role in this work going forward," he added.

Uncle Sam previously injected about $40m into exascale research.

"Here's another way to think about this R&D investment," said Nicole Hemsoth, co-editor of our sister site The Next Platform, in an analysis of today's news. "$258 million in funding across six companies to develop something that might be able to stand in as the correct architecture eventually."

Meanwhile, the government is said to be renegotiating with Intel and Cray over the construction and installation of the $200m 180-petaFLOPS Aurora supercomputer. It was due to arrive in 2018, but it looks as though that deadline will be pushed back as the vendors and the Department of Energy hammer out a new contract. ®

  • Tesla driver charged with vehicular manslaughter after deadly Autopilot crash

    Prosecution seems to be first of its kind in America

    A Tesla driver has seemingly become the first person in the US to be charged with vehicular manslaughter for a deadly crash in which the vehicle's Autopilot mode was engaged.

    According to the cops, the driver exited a highway in his Tesla Model S, ran a red light, and smashed into a Honda Civic at an intersection in Gardena, Los Angeles County, in late 2019. A man and woman in the second car were killed. The Tesla driver and a passenger survived and were taken to hospital.

    Prosecutors in California charged Kevin George Aziz Riad, 27, in October last year though details of the case are only just emerging, according to AP on Tuesday. Riad, a limousine service driver, is facing two counts of vehicular manslaughter, and is free on bail after pleading not guilty.

  • AMD returns to smartphone graphics with new Samsung chip for your pocket computer

    We're back in black

    AMD's GPU technology is returning to mobile handsets with Samsung's Exynos 2200 system-on-chip, which was announced on Tuesday.

    The Exynos 2200 processor, fabricated using a 4nm process, has Armv9 CPU cores and the oddly named Xclipse GPU, which is an adaptation of AMD's RDNA 2 mainstream GPU architecture.

    AMD was in the handheld GPU market until 2009, when it sold the Imageon GPU and handheld business for $65m to Qualcomm, which turned the tech into the Adreno GPU for its Snapdragon family. AMD's Imageon processors were used in devices from Motorola, Panasonic, Palm and others making Windows Mobile handsets.

    'I recognize that I come across as lacking empathy,' billionaire VC admits

    Billionaire tech investor and ex-Facebook senior executive Chamath Palihapitiya was publicly blasted after he said nobody really cares about the reported human rights abuse of Uyghur Muslims in China.

    The blunt comments were made during the latest episode of All-In, a podcast in which Palihapitiya chats to investors and entrepreneurs Jason Calacanis, David Sacks, and David Friedberg about technology.

    The group were debating the Biden administration’s response to what's said to be China's crackdown of Uyghur Muslims when Palihapitiya interrupted and said: “Nobody cares about what’s happening to the Uyghurs, okay? ... I’m telling you a very hard ugly truth, okay? Of all the things that I care about … yes, it is below my line.”
