The U.S believes it will be ready to seek vendor proposals to build two exascale supercomputers—costing roughly $200 million to $300 million each— by 2019.
The two systems will be built at the same time and will be ready for use by 2023, although it’s possible one of the systems could be ready a year earlier, according to U.S. Department of Energy officials.
But the scientists and vendors developing exascale systems do not yet know whether President-Elect Donald Trump’s administration will change directions. The incoming administration is a wild card. Supercomputing wasn’t a topic during the campaign, and Trump’s dismissal of climate change as a hoax, in particular, has researchers nervous that science funding may suffer.
