Accessing RCC clusters

This tutorial shows the basic steps to use the Midway3 cluster at the RCC. For complete RCC technical documentation, see the main sections of this user guide. The information here describes how users can connect to Midway to access RCC resources. All users are responsible for knowing and abiding by the RCC User Policy.

RCC account credentials

To connect to RCC resources, you must have an RCC user account (request an account). Your RCC account uses your UChicago CNetID and its corresponding password:

Username: CNetID
Password: CNetID password

Copy code

Wherever you see grey boxes like the one above, click the icon in the top right corner of the box to copy the contents to your clipboard. It's especially useful for longer code snippets!

After putting in your password, you will choose an option to accept a push on the Duo app. If successful, you will land on your home folder on the Midway3 login node as shown at the command prompt `[your-cnetid]@midway3-login3` or `[your-cnetid]@midway3-login4`.

You can check where the present working directory by running the command `pwd`:
pwd
