This 3-hour workshop series will introduce you to the concepts in High-Performance Computing, as well as the Illinois Campus Cluster and its operations. This includes shell basics, cluster structure and operations, batch job management, the environment, and related topics of convenience for users. (We assume that you have some command-line experience before, with either PowerShell or Bash.) Users are encouraged to bring a laptop and follow along with the exercises. Installation instructions (if necessary) will be provided. This material is presented by Computational Science and Engineering and sponsored by the Illinois Campus Cluster Program.
