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.

Elsa Gonsiorowski helps users and applications perform their best
“If applications don’t read and write files in an efficient manner,” system software developer Elsa Gonsiorowski warns, “entire systems can crash.”
HPSS: High Performance Storage System
Livermore’s archive leverages High Performance Storage System (HPSS), a hierarchical storage management (HSM) application that runs on a cluster architecture that is user-friendly, extremely scalable, and lightning fast. The result: Vast amounts of data can be both stored securely and accessed quickly for decades to come.
