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.

New Account Setup outlines how to get an account on the Open Computing Facility (OCF) CZ and RZ systems and the Secure Computing Facility (SCF). You may also use the Livermore Computing (LC) Identity Management (IDM) System to request and manage accounts.

Use these instructions to connect to both classified and unclassified HPC machines at LANL.

This page provides links to ASC policies, LC policies, and LLNL policies.

Forms are provided for those requests not available through the LC IdM System. Interactive HTML and PDF versions are forms you complete on the Web. Non-interactive PDF versions are to print out and complete by hand.

This is a policy governing the use of the /usr/gapps subdirectory, available on LC production computing resources.

The /usr/gapps file system contain user-supported files that are shared with a number of users, such as applications codes, files used to execute these codes, and source codes maintained or used by a group of LC users.

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 (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).
