What are SSH keys SSH keys are a pair of cryptographic keys that enable secure, password-less remote access to servers and other systems. Amplifying Workflow with SSH Authentication SSH authentication serves as a significant enhancer of your research workflow when working with High Performance Computing (HPC) resources. It paves the way for smooth file transfers between your local computer and the server straight from terminal, eradicating the need for repeated password input.

Overview Roar Collab is Penn State’s High-Performance Computing (HPC) Cluster. In this post, I will lay out the basic tools needed to use it. Here, I assume: You have already created an account and have access. Otherwise, follow the official documentation for instructions. Basic knowledge on Linux and using the comand line/bash shell. If not, check “Command Line Basics”. For the remainder of this tutorial, I will refer to Roar Collab as Rcollab.
