Amazon's cloud unit taps own chips for new supercomputing offering

Dec 1 (Reuters) - Inc’s cloud unit on Tuesday offered a new supercomputing service based on its self-designed processors, a further sign of how chips based on Arm Ltd’s technology are encroaching on Intel Corp and Advanced Micro Devices Inc turf.

Amazon Web Services, or AWS, sells its computing services based on the customer’s choice of an underlying central processor chip. Software developers have traditionally chosen between Intel or AMD products, but since 2018 Amazon has also offered its own “Graviton” chips designed with technology from Arm, which is in the midst of a $40 billion takeover by Nvidia Corp.

Arm-based chips have long powered mobile phones because they can operate on very low power levels, but they are increasingly used in data centers where their power efficiency helps control costs. The world’s fastest computing system, the Fugaku supercomputer in Japan, is based on Arm chips.

Supercomputing helps with tasks such as weather forecasting, medical research and modeling aerodynamics for cars without a wind tunnel. But systems remain expensive and mostly operated by governments and research centers.

AWS is hoping to slash costs, saying the new service will get 40% better price-to-performance than its similar offerings from AMD and Intel. AWS’s own technology will quickly pass data through multiple Graviton processors, a key supercomputing process in which many chips act as a hive mind to tackle a large task. AWS will rent the service out so that researchers need not build or manage a system.

Supercomputing “is no longer this thing that only governments do,” Dave Brown, vice president of Elastic Compute Cloud at AWS, said in an interview. “You can decrease the cost – you don’t need a supercomputer any more. You can spin them up in the cloud and then spin them down.” (Reporting by Stephen Nellis in San Francisco; Editing by Richard Chang)
