Connecting to the system¶
There are two main systems to connect to, interconnected by the network filesystem (i.e. $HOME and $PROJECT, read more in the Data Management section):
- The Neocortex system (contains the Cerebras CS machines, driven by the HPE Superdome Flex system)
- The Bridges-2 system (provides access to the GPU partition on Bridges-2)
There are also two different ways to connect to the system:
- via a web interface using the Open OnDemand platform
- via a command line interface over SSH
Please read below and connect to the system as needed. The resource usage will be tracked for each project.
Connecting to Neocortex (preferred)¶
Info
If you forget your Neocortex authentication credentials, please visit the PSC Password Change Utility webpage.
Neocortex users have been granted Neocortex resources for their projects (please refer to the Allocations section for more information). You will get to compile code, validate code, and run training jobs on the CS machines using this system.
How to connect to Neocortex over SSH?¶
Connect to neocortex.psc.edu using your PSC credentials.
How to connect to Neocortex using Open OnDemand?¶
Navigate to the Neocortex Open OnDemand webpage and login using your PSC credentials.
Connecting to Bridges-2¶
Neocortex users have been granted Bridges-2 resources for their projects (please refer to the Allocations section for more information).
You will get to validate/compile code using this resource, and you also have access to GPUs on this system; however, you will not get to run training jobs on the CS machines from Bridges-2, as those are only available in Neocortex.
How to connect to Bridges-2 over SSH?¶
Info
If you forget your Neocortex authentication credentials, please visit the PSC Password Change Utility webpage.
Connect to bridges2.psc.edu using your PSC credentials.
How to connect to Bridges-2 using Open OnDemand?¶
You can also use Open OnDemand on Bridges-2. For doing so, navigate to the Neocortex Open OnDemand webpage and login using your PSC credentials.
