Last October, we helped celebrate Petascale Day with a panel on the scientific potential of new supercomputers capable of running more than a thousand trillion floating point operations per second. But the ever-restless high performance computing field is already focused on the next landmark in supercomputing speed, the exascale, more than fifty times faster than the current record holder (Titan, at Oak Ridge National Laboratory). As with the speed of personal computers, supercomputers have been gaining speed and power at a steady rate for decades. But a new article in Science this week suggested that the path to the exascale may not be as smooth as the field has come to expect.

The article, illustrated with an image of a simulated exploding supernova (seen above) by the CI-affiliated Flash Center for Computational Science, details the various barriers facing the transition from petascale to exascale in the United States and abroad. Government funding agencies have yet to throw their full weight behind an exascale development program. Private computer companies are turning their attention away from high performance computing in favor of commercial chips and Big Data. And many experts agree that supercomputers must be made far more energy-efficient before leveling up to the exascale — under current technology, an exascale computer would use enough electricity to power half a million homes.
