SAN FRANCISCO - The US Department of Energy disclosed details Monday of one of the most expensive computers being built: a US$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.
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. Aurora - which is also designed to exploit new advances in the field of artificial intelligence, including machine learning techniques pushed lately by the likes of Google and Facebook - may not crack the new speed barrier first.
Supercomputer speeds are not usually discussed much until machines run standard performance tests. But the stakes associated with the shift to exascale systems, and their enormous price tags, have attracted outsize attention. Energy Secretary Rick Perry, who took part in the event discussing Aurora on Monday, announced a plan last year to spend up to US$1.8 billion on two to three exascale systems.
The version of Aurora announced in 2015 was based on an Intel accelerator chip that the company later discontinued. A revised plan to seek more ambitious performance targets was announced two years later.
