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.

This issue has been resolved.
Some users are currently unable to access their home drives on Argon. Affected users may receive an error message like “Could not chdir to home directory /Users/hawkid: No such file or directory” when trying to access their Argon home directory.
IDAS users might receive errors starting an IDAS session when requesting their hpchome be mounted.
ITS is investigating this issue and updates will be posted on the HPC System News support page.

This issue has been resolved.
Argon and IDAS are currently unavailable. Users are seeing failed or stalled logins when attempting to connect to Argon. IDAS will still continue to function if Argon Homes or LSS are not being used. IDAS class instances are down if they have shared libraries or shared storage.
Research Services is investigating this issue. Further update information can be found at https://hpc.uiowa.edu/system-news/argon-login-issues
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
See Fall 2021 HPC maintenance | High Performance Computing for more information.
The Argon HPC system will be in a regularly scheduled quarterly maintenance. For more details, see: HPC Summer 2021 Maintenance
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.
