High performance computing is seemingly becoming a way of life in many fields, both for research and for industry. Cloud services such as Amazon Web Service, Microsoft Azure, Digital Ocean, and a number of others allow for quick execution of tasks commonly found in many research areas. The University of Iowa maintains a high performance computing system (Argon) that allows for processing of such tasks with a Linux operating and scheduling system that is similar to those found on other cloud platforms.

Access to such a system means no longer having to manage multiple desktop computers to execute enough replications of a simulation study or no longer having to find a desktop or laptop with enough RAM to make a program run. Overall, the quality and depth of research can be greatly expanded by using a HPC resource like Argon.

University of Iowa HPC Information

In this post, I outline how to access and use the Argon HPC via an R Studio Server run through the Iowa Interactive Data Analytics Service (IDAS) system.

Prerequisites

To follow this guide, you must first have the following:

  1. A University of Iowa Argon account. You can request one from: https://research.its.uiowa.edu/our-services/computing-services/argon-high-performance-computing-hpc
  2. A University of Iowa Interactive Data Analytics Service Account. You can request one from: https://its.uiowa.edu/idas
  3. A download of the following file: https://jonathantemplin.com/wp-content/uploads/2023/08/ArgonDemo.zip

Video Demonstration

To show how to connect to Argon via IDAS and how to execute these job scripts, please watch the following video:
