I/O, Networking, and Storage

Disk- and tape-delivered I/O bandwidths are being rapidly outpaced by capacity increases, which means valuable processor time is being wasted while waiting for data delivery. For extreme-scale machines to be productive, bandwidth challenges throughout the entire I/O stack must be addressed. We’re working on techniques and technologies that leverage node-local or near-node storage, refactor parallel file systems, and evolve tertiary storage software to enable efficient extreme-scale computing environments.

Podcast: Software Enables Use of Distributed In-System Storage and Parallel File System

A software product from the ECP called UnifyFS can provide I/O performance portability for applications, enabling them to use distributed in-system storage and the parallel file system.
