The High Performance Storage System (HPSS), the archival storage system for the Livermore Computing (LC) open and secure computing facilities, provides different classes of service (COS) for storing files. The Data Storage Group has configured HPSS to use different COS to make the best possible use of available hardware resources. To date, the user interface automatically selects the COS in which to store a file.

This page lists available online tutorials related to parallel programming and using LC's HPC systems. NOTE: archive tutorials are no longer updated and may contain broken links and other QA issues.

Livermore Computing provides first-class computational infrastructure that supports the computing requirements of the Laboratory's scientists. In addition, LC develops High Performance Computing (HPC) solutions, in collaboration with partners at Los Alamos and Sandia National Laboratories, for use by the Advanced Simulation and Computing Program.

EZFILES helps you effectively manage your files and directories on Livermore Computing (LC) computers. EZFILES explains the hierarchical structure of directories and file systems on LC computers, the properties and limits of those directories, the role of the common home directory, and the default search paths.

This manual introduces tools for effectively storing and archiving files from Livermore Computing (LC) computers by using the High Performance Storage System (HPSS), also referred to herein as "storage."

HTAR ("HPSS Tape Archiver") is an LC-designed TAR-like utility program that makes TAR-compatible archive (library) files but with High Performance Storage System (HPSS) support and enhanced archive-management features.
