Obama wants the US to build the world's first exascale supercomputer

President Obama has issued an executive order authorizing the creation of a National Strategic Computer Initiative that will attempt to build the first ever exascale computer, which would be 30 times faster than today’s fastest supercomputer.
The new initiative will see collaborations between the Department of Energy, Department of Defense and the National Science Foundation, with NASA, the FBI, the National Institutes of Health, the Department of Homeland Security, and NOAA providing input during the early stages of development. The primary task of the initiative is accelerating delivery of a capable exascale computing system.
“Computational problems and data centric problems are coming together in areas that range from energy, to climate modeling, to healthcare. This shift dictates the need for a balanced ecosystem for high performance computing with an undergirding infrastructure that supports both computationally-intensive and data centric computing.”
Currently, the fastest supercomputer in the world is China’s Tianhe-2, which runs at 33.86 petaflops. This means it is capable of performing 33.86 quadrillion floating point operations per second. The second fastest supercomputer in existence resides in the US; Titan Cray XK7, a machine at the Oak Ridge National Laboratory in Tennessee, runs at 17.59 petaflops.
The United States still has more entries on the Top500 list of supercomputers than any other country; it houses 233 of the world’s fastest computers, Europe 141 and China 37.
The National Strategic Computer Initiative seeks to build a supercomputer capable of running at 1000 petaflops or higher, which would make it the world’s first exaflop computer. This would give it the ability to perform one quintillion (a billion billion) calculations per second, which is believed to be the order of processing power of the human brain at neural level.
There was no timeline provided as to when this project will be completed, although the executive order did state that NSCI must be setup within 90 days of today and must release annual reports about its progress.

Obama orders creation of exascale supercomputer
Can the president's executive order prompt the development of computer systems capable of running at 1 exaflops?
By Charlie Osborne for Between the Lines | July 30, 2015 -- 07:56 GMT (08:56 BST)
US President Obama is seeking the might of exascale computers to power the country's government departments in the future.
In a new executive order, the president has issued demands for a new initiative which will focus exclusively on supercomputing research, released by the White House on Wednesday. Titled "Creating a national strategic computing initiative," the president's order outlines plans to create the world's first exascale computing system in order to establish the country's position in high-performance computing (HPC) research and development.
An exascale system would be capable of performing 1 million trillion floating-point operations per second -- otherwise converted as 1,000 petaflops or 1 exaflops -- which is far quicker than today's supercomputers.
However, such a system would need an architecture capable of combining thousands of high-power processors and CPUs, a complete overhaul of how today's computers operate, and would require a fortune in energy and building costs based upon today's system usage rates.
As reported by IEEE Spectrum, an exascale computer could be built, but current systems simply aren't tenable. Steve Scott, senior vice president and chief technology officer at Cray told the publication:
"To some degree it depends on how much money a country is willing to spend. You could build an exaflop computer tomorrow, but it'd be a crazy thing to do because of the cost and energy required to run it."
Despite this, HPC research has to start somewhere. Obama's order has led to the launch of the National Strategic Computing Initiative (NSCI), a "whole-of-government effort designed to create a cohesive, multi-agency strategic vision and Federal investment strategy, executed in collaboration with industry and academia, to maximize the benefits of HPC for the United States."
The initiative will primarily be a partnership between the US Department of Energy (DOE), the Department of Defense (DOD), and the National Science Foundation (NSF), although the private sector will also be consulted.
The US president believes that increased demand for computing power and maintaining economic growth requires the high performance of next-generation computers. As a result, the new federal strategy aims to propel research in this area forward through orders for the US to deploy and apply HPC technologies across the board, the fostering of growth for public-private collaborative research efforts and increased communication between different government departments, academic institutions and companies.
In addition, Obama says the US must develop a "comprehensive technical and scientific approach" to extend HPC research into hardware, system software, development tools, and applications.
Ultimately, the NSCI is tasked with the development of an exascale computing system which can deliver approximately 100 times the performance of current 10 petaflop systems across a range of applications for government use.
The initiative is also expected to provide, "over the next 15 years, a viable path forward for future HPC systems even after the limits of current semiconductor technology are reached (the "post- Moore's Law era")," according to the order.
If exascale supercomputers become reality through the initiative, NASA, the Federal Bureau of Investigation (FBI), the National Institutes of Health, the Department of Homeland Security, and the National Oceanic and Atmospheric Administration (NOAA) will benefit the most -- and have the option to pitch in their own ideas, requirements and applications through the research process.
While there is no definitive timeline for the NSCI to pull an exascale computer out of the hat, the group's council is required to submit a plan for the development of exascale computers within 90 days of the order being issued and check-in with updates annually.
