The promise of exascale computing


The growing power of supercomputers continues to push the boundaries of our knowledge, whether we’re exploring the workings of the universe or looking for better ways to promote clean energy and human health.

Researchers including those at the DOE-supported Exascale Computing Project are preparing for the next computing milestone, which will produce systems performing over a quintillion calculations each second. By contrast a person doing one calculation each second would take more than 30 billion years to reach a quintillion.

Here are just a few ways exascale computers will expand research and development, compared to a single desktop computer and to the nation's most powerful computer today, the Titan system at the Oak Ridge Leadership Computing Facility.
