Hopper

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.

Retrieve files on the SCF by using SFTP/SCP, FTP or Hopper to make a copy of a file from the transfer server to your local machine. Initiate the FTP client software, connect to fastfis.llnl.gov, and complete the authentication process (by specifying a user name and SCF password). After you have connected to to fastfis.llnl.gov, change to your FROM directory and list the file(s) in the directory.

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).

Here are a number of the more popular tools you'll find on LC systems for moving data between different destinations.

Useful introductory information on LC's software environment is presented in the Software and Development Environment section of the Introduction to Livermore Computing Resources, or the Linux Clusters Overview for system-specific information.

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