Initial Login
- Install a time-based, one-time password (TOTP) application, such as FreeOTP, Google Authenticator, or BNL Duo.
- Login with your SDCC account (not BNL or other accounts):
The Department of Energy (DOE) mandates that all DOE facilities use two-factor authentication methods on all gateways into the facility that provides shell access. The SDCC gateways support SSH key login.
Gateway Machines
See our gateway information page for a list of gateways and complete details.
SSH keys are a public/private key pair that allows login to an SSH daemon (sshd) without using a password. SSH keys are generated using the ssh-keygen program on Linux/Unix/ macOS/Cygwin, or with PuTTYgen on Windows.
Note: SSH keys are checked within the sshd program itself, thereby taking precedence over the other authentication methods.
How to use your SSH key pair to log into another remote machine.
There are a number of problems that can cause failures when connecting to the SDCC. Here are some things to look for and try in order to resolve your problem.
Private and Public Key Issues
- Have you uploaded your public key to the SDCC via the key file upload form (requires your Kerberos user name and password)?
Each time you log into a remote host using SSH keys, you will be prompted to supply the pass phrase used to lock your private key. There is an SSH agent that will hold your private key for you, respond to the SSH transaction, and supply the key as needed. You start the SSH agent with the command:
Using the Institutional Cluster (IC), including information about central storage, backups, and transfers.
Currently, central storage for the Institutional Cluster (IC) is provided by IBM's Spectrum scale file system (GPFS), a high-performance, clustered filesystem that supports full POSIX filesystem semantics.
If you have used our previous cluster, your files from 'nano' (including /home, /work, and /gscr) are now stored at /hpcgpfs01/cfn/. Please copy those files to your current home directory.

Overview
The new CRS Batch software was designed to allow users a transparent transition from old CRS batch software, whenever possible. In many instances, functionality and flexibility of the new software has been enhanced to address users' requests. An example is the ability of the new CRS batch software to leverage the use of commodity hardware (Intel-based servers) and open-source Linux OS to simplify the interface to the RCF/ACF mass storage system (HPSS).
New Features
The new CRS system has a number of enhancements and new features.
