Exascale Computing

(exaFLOP computing capability, i.e., quintillion FLOPs)

The term Exascale Computing is used for computing on the scale of ExaFLOPs, i.e., a quintillion FLOPs, or 1018 floating point arithmetic operations performed per second, specifically the ability to dedicate such a capability to a single task, model, simulation, or calculation. As of 2017, the capability is merely a goal, pursued by the larger technically-capable countries, to use and push the decreasing cost of computing for more ambitious scientific analysis. Target dates to achieve the capability are generally around 2020. Scientific analysis that requires Three Dimensional Models will be more practical, such as Core Collapse Supernova models and other astrophysical phenomena.
