Use these instructions to connect to both classified and unclassified HPC machines at LANL.
LC provides the /usr/gapps file system for user-developed and supported applications on LC systems. There is a single /usr/gapps file system globally available to all LC systems within a given zone or network (three on OCF and one on SCF). This global file system replaces the previous /usr/apps file systems that were local to each production system or cluster.
There are three instances of /usr/gapps on the OCF:
Trans is a utility from the Cray machines that has been ported to run on the IBM machines. It knows about several forms of files on older machines and how to convert them for use on current machines.
LC has archival storage systems for moving files between LC file systems and HPSS archival storage on all three networks: CZ, RZ, and 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).
Both TapeFIS and OWL (one-way link) FIS are available on the iSNSI network. iSNSI TapeFIS is bidirectional and requires Derivative Classifier (DC) intervention for file transfers from Pinot to the OCF. Login examples are provided below. OWL transfers are significantly faster but are unidirectional for transfers from CZ and RZ to the SCF.
Hopper is a powerful interactive tool that allows users to graphically move, copy, find, delete, and otherwise operate on files. Users can connect to and manipulate resources using ftp, ssh, sftp, htar, Endeavor (nft), and other protocols.
The Livermore Computing (LC) file interchange service (FIS) allows LC users to transfer files between the unclassified Open Computing Facility (OCF)—both the Collaboration Zone (CZ) and the Restricted Zone (RZ)—and the classified Secure Computing Facility (SCF). This document describes how FIS works and how to use it effectively.
