SDSC Voyager Habana Training and Inference Processor based AI System

Voyager uses ssh key pairs for access.

Approved users will need to send their ssh public key to consult [at] sdsc.edu (consult[at]sdsc[dot]edu) to gain access to the system.

To log in to Voyager from the command line, use the hostname:

login.voyager.sdsc.edu

The following are examples of Secure Shell (ssh) commands that may be used to log in:

ssh <your_username>@login.voyager.sdsc.edu ssh -l <your_username> login.voyager.sdsc.edu

Notes and hints

• Voyager will not maintain local passwords,  your public key will need to be appended to your ~/.ssh/authorized_keys file to enable access from authorized hosts. We accept RSA, ECDSA and ed25519 keys. Make sure you have a strong passphrase on the private key on your local machine.
  • You can use ssh-agent or keychain to avoid repeatedly typing the private key password.
  • Hosts which connect to SSH more frequently than ten times per minute may get blocked for a short period of time
• Do not use the login node for computationally intensive processes, as hosts for running workflow management tools, as primary data transfer nodes for large or numerous data transfers or as servers providing other services accessible to the Internet. The login nodes are meant for file editing, simple data analysis, and other tasks that use minimal compute resources. All computationally demanding jobs should be run using kubernetes.

MFA

Voyager does not maintain local passwords and relies entirely on SSH key pairs. Keys must be appended to ~/.ssh/authorized_keys. RSA, ECDSA, and ed25519 keys are accepted, and a strong passphrase on the private key is required.
