Don't let go!

Singer Hall at Swarthmore College, a modern gray building with many reflective windows.

Registration for Linux Clusters Institute Intermediate Workshop is now open! June 1-5 at Swarthmore College. Details at linuxclustersinstitute.org/2026-lci-int...

Good for you! 😎

Correct. And you don't have to trust Claude's build-in safeguards, which may not work when Claude executes binaries or writes it's own code. The container (and the Linux kernel) enforce the limits on a lower level.

It really depends on your needs. We have users that have access to data that MUST NOT leak. For those, the only way to use AI at least in a limited fashion is in a container. "Inconvenient" beats "impossible". 😎

Yes, RW or RO are both supported.

Apptainer is also the only such tool available on our HPC systems. 😁

Here is a screenshot of the cmdln version. The first parameter is the directory to be "mounted inside the container", and all other parameters are passed through to Claude. Behind the scenes it "module load apptainer", pulls a minimal container, configures the "bind mounts" and starts Claude.

The story is easy access to AI in an #HPC environment, with limitations enforced by the container and not by Claude settings. The limitations extend to Claude's tool calls and applications because everything runs in the container. Not new, but existing capabilities exposed in a user friendly fashion

I sure hope not...😂

Worried about Claude Code accessing sensitive data? How about an icon on the #HPCDesktop that limits Claude's access? I prototyped this using #Apptainer. This enforces real limits for Claude Code and any app it launches. (and for the #HPC folks, there is also a cmdln version 😎)

Must refrain from commenting on Fleischsalat....

Interesting that this made it into the international press.

The deadline for paper submissions to the Interactive and Urgent #HPC workshop at #ISC26 is approaching. www.interactivehpc.com/cfp Please consider submitting and reach out if you have questions.

I really enjoyed attending #HPC #GOOD26, organized by Open OnDemand and the Ohio Supercomputer Center. Looking forward to coming back next year!

This looks like a good day to fly. I am on my way to Salt Lake City for this year's Open OnDemand conference. #hpc #good26 #ood

Next week, I will be presenting on my favorite topic, the #HPCDesktop at this year's Open OnDemand Conference - www.good2026.openondemand.org. Looking forward to meeting all the nice folks behind OOD! #HPC #OOD

Excellent reminder of where we are going thanks to AI....

ORNL, Genesis and AI
#EnergyHPCAI #hpc

Day 2 Rice Energy HPC and AI conference. Let's see what LLMs can do for compilers.
#EnergyHPCAI #hpc

This should be interesting... #EnergyHPCAI #hpc

Opening panel "Understanding the Value of HPC", with representatives from HPC centers and industry. #EnergyHPCAI #hpc

This is my first time at the #EnergyHPCAI conference. Looking forward to it! I will be representing Cendio ThinLinc at the conference.

I use LLAMA 4 Scout and it works well and fast on H100s. The parameters are pretty limited and the sacct syntax is pretty straightforward as well.

Don't have a GUI environment available on your #HPC system, thats unfortunate and you should consider an #HPCDEsktop... but converting to a TUI was an easy one-shot by the LLM. 🤯

In 90 minutes I went from idea to prototype, thanks to Cursor/Opus 4.6. My app uses a local LLM to turn text into #SLURM sacct/squeue calls and then shows the result in a table. It's not perfect; the system prompt needs tuning; but amazing what is possible as a user on an #HPC system. #HPCDesktop

Are you working on something cool related to interactive or urgent #HPC? Please consider submitting to our workshop at #ISC26. Paper submission closes on March 25th! Reach out with questions!

Looking for feedback on an #HPC "batch job wizard", as shown in the video. The core idea is to iteratively build a #Slurm job script, highlighting the relation between the GUI and the Slurm directives. The video shows a prototype QT/Python app on an #HPCDesktop. Could this work for new HPC users?

"The year in code" is a really fun way to summarize how I used Cursor this year. No surprise here... I mostly use Claude Sonnet and Opus.

I remember sitting in a presentation at ISC back in 2009 by Argonne about running Plan9 on an IBM BlueGene. 😁
