High performance computing (HPC) accelerates the process of research discovery. Most domains now use HPC, and research is increasingly compute- and data-intensive as more scientists and engineers employ machine learning, neural networks and other artificial intelligence (AI) workflows. 

In collaboration with other units on campus, ITS-Research Services supports the Argon HPC system which features ~16,000 CPU processors and more than 300 GPU accelerators. 

The Interactive Data Analytics Service (IDAS) is a computational resource, launched mid 2019, that supports large-scale and collaborative data analytics workflows involving RStudio for R, Jupyter Notebook for Python, and more. Users may access HPC resources within the IDAS interface using Jupyter Notebooks, while performing interactive data analysis tasks with applications used for AI workflows.  

HPC and data science workshops are offered by ITS-RS training personnel; watch for upcoming sessions on the HPC website

Logins to the Argon HPC system may periodically fail due to an unresponsive login node. ITS is currently investigating the issue.

Users experiencing issues connecting to argon.hpc.uiowa.edu should connect to a login node directly instead:

  • argon-login-1.hpc.uiowa.edu
  • argon-login-3.hpc.uiowa.edu
  • argon-login-4.hpc.uiowa.edu

The issue has been resolved.


One of the servers for the Argon Home directories is having an issue with file locks. If your home account is on this server, you may experience processes that get stuck shortly after launching. The problem is being investigated and will be mitigated as soon as possible.
