SAN FRANCISCO — The Department of Energy disclosed details on Monday of one of the most expensive computers being built: a $500 million machine based on Intel and Cray technology that may become crucial in a high-stakes technology race between the United States and China.
The supercomputer, called Aurora, is a retooling of a development effort first announced in 2015 and is scheduled to be delivered to the Argonne National Laboratory near Chicago in 2021. Lab officials predict it will be the first American machine to reach a milestone called “exascale” performance, surpassing a quintillion calculations per second.
That’s roughly seven times the speed rating of the most powerful system built to date, or 1,000 times faster than the first “petascale” systems that began arriving in 2008. Backers hope the new machines will let researchers create significantly more accurate simulations of phenomena such as drug responses, climate changes, the inner workings of combustion engines and solar panels.

Supercomputers, which play a major role in tasks such as weapons design and code-breaking, have long been considered a proxy for national competitiveness in science and technology. The United States led the field for decades, but China has become an aggressive rival.
An IBM system called Summit, built for the Oak Ridge National Laboratory in Tennessee, took back the No. 1 position last year on a twice-yearly ranking of the world’s 500 most powerful systems — a spot held by China for five years.
But China leads by another key measure: It accounted for 227 systems on the…The post Racing Against China, U.S. Reveals Details of $500 Million Supercomputer appeared first on FeedBox.
