Learning With the Flow

The bigger the swirl, the bigger the problem — and the bigger the computing power needed to solve it. Computational fluid dynamics researchers have spent decades studying how liquids and gases flow in and around such machinery as airplane wings, propeller blades and jet engines in search of faster speeds…

The Climate in a Container

Successfully running a simulation program on a supercomputer requires more than just writing code. An application such as a climate model requires libraries, network support, and the correct operating environment. Because of these complex and multilayered requirements, applications are typically customized and built natively on a computing system, making them…
