The Road to Exascale

Solving the world’s biggest challenges requires the most sophisticated scientific tools, including fast and powerful supercomputers. That’s why the US Department of Energy (DOE) devotes so many resources to designing and building next-generation systems. But back in 2008, the feasibility of exascale-class computing—supercomputers that can perform exaflops, or a billion…

Exascale Computing’s Four Biggest Challenges and How They Were Overcome

In 2008, the Exascale Study Group (ESG) issued a report, Technology Challenges in Achieving Exascale Systems, sponsored by the Defense Advanced Research Projects Agency. It concluded that exascale supercomputers faced four major obstacles—power consumption, data movement, fault tolerance, and extreme parallelism—“where current technology trends are simply insufficient, and significant new…
