The GSL now uses a secure encrypted FTP server (FTPS not SFTP) for data transfer. You will receive an email regarding login information. Please use an FTP client (e.g., FileZilla) or FTP from the command-line (e.g., lftp) that supports explicit FTPS. You may allow for multiple parallel connections to speed up downloading. Basic instructions for FileZilla and command-line as well as troubleshooting suggestions are detailed below.

Command-line lftp is the best option for transferring data to Berkeley’s computing cluster. You must be logged into a data transfer node ( and not a login node. See the Berkeley HPC user guide for further details.
