The PowerOmics login nodes can be accessed through Secure Shell from any machine on the Rice campus network and certain Texas Medical Center campus networks.

If you need off-campus access, please visit our Off-Campus Access Guide

To login to the system from a Linux or Unix machine, use the ssh command:

To transfer files into the cluster from a Linux or Unix machine, use the scp command:

For more information about using Secure Shell, please see our Using SSH to Login and Copy Files Guide.

First Time Login

If this is the first time you are logging in and you need login instructions, please see our FAQ .

Login Nodes

Once you are logged in to the system, you are logged into one of several login nodes as shown in the diagram below. These nodes are intended for users to compile software, prepare data files, and submit jobs to the job queue. They are not intended for running compute jobs. Please run all compute jobs in one of the job queues described later in this document.

Do not run compute jobs on login nodes

Cluster login nodes are multi-user access points intended for users to compile software, copy and prepare data files, and submit jobs to the job queue. Any user running intensive computational tasks directly on the login node risks disciplinary action up to and including the loss of their access privileges.
