Introduction to Using the Shell in a High-Performance Computing Context

This workshop is an introduction to using high-performance computing systems effectively. We obviously can’t cover every case or give an exhaustive course on parallel programming in just two days of teaching time. Instead, this workshop is intended to give students a good introduction and overview of the tools available and how to use them effectively.

By the end of this workshop, students will know how to:

Use the UNIX command line (also known as terminal or shell) to operate a computer, connect to a cluster, and write simple shell scripts.

Prerequisites

There are no real prerequisites for this lesson, but prior programming and/or command line experience will be helpful.
