On Wednesday, July 12, the Livermore Computing Data Storage Group will release a new version of HTAR on all open (OCF) and secure (SCF) production machines. HTAR—a utility that combines a flexible file-bundling tool with fast parallel access to high performance storage—allows users to store and selectively retrieve very large sets of files efficiently. This update to HTAR allows specifying entries to exclude during creation of new archive files.

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 page describes training materials that are available, including workshops, online training, user manuals, and resources for new employees.

In addition to our Tutorials, users of Livermore Computing (LC) systems have access to several types of user information and documentation. Questions may be directed to the LC Hotline via e-mail or via telephone at (925) 422-4531. 

Slurm is a combined batch scheduler and resource manager that allows users to run their jobs on Livermore Computing’s (LC) high performance computing (HPC) clusters.  This document describes the process for submitting and running jobs under the Slurm Workload Manager.

IBM Spectrum LSF is a batch scheduler that allows users to run their jobs on Livermore Computing’s (LC) Sierra (link is external) (CORAL) high performance computing (HPC) clusters. IBM Cluster System Management (CSM) is the resource manager for the Sierra systems.

This is a quick start guide for LSF, a batch scheduler that allows users to run their jobs on Livermore Computing’s (LC) Sierra (link is external) (CORAL) high performance computing (HPC) clusters.

The Livermore Computing (LC) Identity Management (IdM) System automates the process of provisioning (creating and updating) and deprovisioning (deleting) user accounts across LC's multiple systems. IdM also allows the management of of accounts, groups, and LC identities for both the Open Computing Facility (OCF)—Collaboration Zone (CZ) and Restricted Zone (RZ)—and the Secure Computing Facility (SCF).

FTP

FTP (File Transfer Protocol) is an industry-standard protocol and user interface for transferring files between computer systems by means of a series of interactive commands. FTP involves a local client (software you execute to send or receive files) and a remote server (software elsewhere that responds to instructions from your client to accept or deliver files).

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.
