Industry Out of Phase With Supercomputers (IEEE Spectrum)

An article in IEEE Spectrum covers a recent report by the National Nuclear Security Administration (NNSA): 

NNSA has developed massive and sophisticated codes that run on supercomputers to verify the continued security and performance of nuclear weapons designed decades ago. Keeping them up to date requires new generations of supercomputers that can run more complex models faster than the months required on today’s machines. But industry, which has shelled out big bucks for state-of-the-art fabs, is targeting big, profitable markets like cloud computing.

US DoE (Argonne) to acquire AMD+Nvidia supercomputer as testbed for delayed Intel-based exascale supercomputer

From Reuters: The Nvidia and AMD machine, to be called Polaris, will not be a replacement for the Intel-based Aurora machine slated for the Argonne National Lab near Chicago, which was poised to be the nation's fastest computer when announced in 2019.

Instead, Polaris, which will come online this year, will be a test machine for Argonne to start readying its software for the Intel machine, the people familiar with the matter said.


Cray and AMD will build 1.5 exaFLOPS supercomputer for DOE

From Ars Technica: AMD and Cray have announced that they're building "Frontier," a new supercomputer for the Department of Energy at Oak Ridge National Laboratory. The goal is to deliver a system that can perform 1.5 exaflops: 1.5×1018 floating point operations per second.

The current (Nov 2018) Top 500 leader, Summit at ORNL, runs at 0.2 exaflops.


U.S. DoE unvails $500m supercomputer

From the New York Times: DoE is unveiling a new $500m exascale supercomputer, produced by a collaboration between Intel and Cray. This is part of the computing arms race with China, which has been making big strides in supercomputing in the past decade.

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.
