Why does the American flag need expensive supercomputers

Jack Dongara spoke to ORNL friends recently.

Due to Frontier, the US ranks first within the record of the five hundred finest supercomputers when it comes to the variety of calculations that may be carried out per second, because of Frontier, the primary $600 million exascale supercomputer from the Division of Power – positioned at Oak Ridge Nationwide Laboratory. However Jack Dongara famous that China, which has two supercomputers ranked sixth and ninth on the record, may surpass the computing energy of america in fixing scientific and technological issues.

Dongarra, with appointments on the College of Tennessee, ORNL, and the College of Manchester within the UK, is that this yr’s winner of the celebrated award AM Turing Award From the Society for Computing Machines, the equal of the Nobel Prize in computing. He holds a prize of 1 million {dollars}.

Dongarra informed FORNL that border Carry out arithmetic at a price of 1.1 exaflops, or 1.1 quintillion arithmetic operations per second – a billion instances a billion floating-point operations per second, or FLOPS (for instance, including and multiplying numbers with decimal factors). Frontier is 5 instances sooner than probably the most highly effective supercomputers in use as we speak.

The latest TOP500 list shows the ORNL Department of Energy's Frontier supercomputer ranks #1 in the world.

To assist his followers perceive the facility of Frontier, which occupies the world of ​​two tennis courts, Dongara recommended we think about Utah has 60 Nieland courts, every with 100,000 seats. To do the variety of calculations per second you may get on Frontier, you would need to give everybody a laptop computer able to 166 billion FLOPS and join the laptops in all of the stadiums collectively.
