Accessing Hydro

Access and Policy

Access to the Hydro cluster is limited to users of allocated NFI projects and Illinois Computes projects. Please see the NCSA Services - Hydro page for additional information on non-NFI funded access to the Hydro cluster.

If you are part of an allocated NFI project and would like access to the Hydro cluster, please submit a support request with a justification for your need to use the cluster.

Logging In

Connect to Hydro via the login hosts at hydro.ncsa.illinois.edu using SSH with your NCSA Duo passcode or push response from your phone app.

For instructions on how to activate your NCSA Duo account, see Duo at NCSA. To check if your NCSA Duo is working properly, log into the NCSA Duo portal and choose an authentication method.

Account Management

For instructions on how to manage a Hydro project group (add and remove users, or set a group delegate), see NCSA Allocation and Account Management. Please note though, that group membership changes synchronize with Hydro every 15 minutes in case your changes are not appearing on the system immediately.
