Serving Data to the Lunatic Fringe: The Evolution of HPC Storage
John Bent, Brad Settlemyer, and Gary Grider
Before the advent of Big Data, the largest storage systems in the world were found almost exclusively within high performance computing centers such as those found at US Department of Energy national laboratories. However, these systems are now dwarfed by large datacenters such as those run by Google and Amazon. Although HPC storage systems are no longer the largest in terms of total capacity, they do exhibit the largest degree of concurrent write access to shared data. In this article, we will explain why HPC applications must necessarily exhibit this degree of concurrency and the unique HPC storage architectures required to support them.
