Expert: Exaflops Supercomputing Is Unlikely in the Near Future

The much-discussed idea that supercomputing performance could soon reach exaflops (1018 floating point operations per second) levels will not be possible before the end of the decade, according to Horst Simon, the US Lawrence Berkeley National Laboratory’s deputy director. A combination of technical challenges are proving an obstacle, including the total power needed by such a system, increased chip power efficiency, and the cost of data movement and memory. “I also think calling the system exa-anything is a bad idea. It’s become a bad brand, associated with buying big machines for a few national labs,” he told HPCWire. “It also sets the community up for a perceived failure if we don’t get to exaflops.” And measuring the system’s performance once it is built also poses a challenge, he adds, estimating an exascale system will need five to six days to run the LINPACK benchmark. A reasonable goal toward exascale computing, Simon said, would be constructing an exascale system that could rank first in the TOP500 supercomputing-performance list by 2020. He says there are projects working in that direction, including the US Department of Energy’s FastForward. Simon says the US needs exascale computing resources to maintain a competitive advantage in manufacturing as well as for national security.

US Agencies Award $62.5 Million for Exascale Computing


The US Department of Energy, Office of Science, and National Nuclear Security Administration has awarded $62.5 million in R&D contracts for exascale-computing projects that can be deployed in national defense, scientific research, and energy security applications. The recipients of the FastForward initiative contracts were AMD, IBM, Intel, Nvidia, and Whamcloud. They now will work on the critical technologies behind energy-efficient computing systems that perform quintillions of floating-point operations per second. Their two-year contracts are for development of processors, memory, storage, and  communication systems between computers and outside networks.
