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.
To connect to a CS-2 login, ssh to login nodes:
The CS-2 cluster has its own Kubernetes-based system for job submission and queuing. Jobs are started automatically through the Python scripts.
Use Cerebras cluster command line tool to get addional information about the jobs.
- Jobs that have not yet completed can be listed as
(venv_pt) $ csctl get jobs - Jobs can be canceled as shown:
(venv_pt) $ csctl cancel job wsjob-eyjapwgnycahq9tus4w7id
See csctl -h for more options.
The Cerebras Hands-on section consists of examples using Cerebras ML software stack and Cerebras SDK.
