Connection to a CS-2 node

Cerebras Wafer-Scale Cluster connection diagram Connection to one of the CS-2 cluster login nodes requires an MFA passcode for authentication - either an 8-digit passcode generated by an app on your mobile device (e.g. MobilePASS+) or a CRYPTOCard-generated passcode prefixed by a 4-digit pin. This is the same passcode used to authenticate into other ALCF systems, such as Theta and Cooley.
In the examples below, replace ALCFUserID with your ALCF user id.
To connect to a CS-2 login:

  1. ssh to a desired login node: 
    ssh ALCFUserID@cer-login-01.ai.alcf.anl.gov
    or 
    ssh ALCFUserID@cer-login-02.ai.alcf.anl.gov
    or 
    ssh ALCFUserID@cer-login-03.ai.alcf.anl.gov
  2. Alternatively, ssh randomly to one of the above three login nodes: 
    ssh ALCFUserID@cerebras.ai.alcf.anl.gov
