Archival Storage

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."

This page lists available online tutorials related to parallel programming and using LC's HPC systems.

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.

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.

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.
