Big data means big issues for exascale computing!


When exascale computers begin calculating at a billion, billion operations each second, gaining insights from the massive datasets generated by the simulations they run will be a huge challenge. Scientists may be tempted to pause the simulation, effectively “holding the machine hostage” as they scramble to create meaningful portrayals of the data barrage, says Hank Childs, a Lawrence Berkeley National Laboratory computer systems engineer. Childs, a recent recipient of a $2.5 million Department of Energy Early Career Research Program award, is out to prevent that.
