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.

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. 😁

Here is a workflow for new #HPC users. It shows how to start an interactive job in #Slurm and connect a resource monitor. I built the GUIs with Cursor, they are Python/QT apps running on an #HPCDesktop. The Slurm GUI is on Github and the job monitor will soon be.

I have been wondering about this as well. They (as in the EU) denoted the LUMI HPC machine as an AI factory and I just don't get it...

Last talk for today is by Jay McGlothlin talking about Implementing support for Interactive and AI workloads in a traditional HPC environment

Up next is Ye Htet, talking about Modeling and Optimizing Real-Time Telescope Interaction for Multi-wavelength Observation of Gamma-ray Burst

Up next, Ketan Maheshwari talking about Evaluating HPC Scheduling Strategies for Urgent Workloads

Next up, Shohei Minami will talk about
Physical System Study on Balancing Interactive and Batch Job Performance through Oversubscribing Scheduling

Alan Chalker is talking about Open OnDemand

And here is the agenda for today.

Go time...

St. Louis's weather is working in our favor! 😁 Join us in room 260 for the Interactive and Urgent #HPC workshop at #SC25. Starting at 8:30. Keynote by Alan Chalker of OOD fame!

If you are attending the Friday workshops at #SC25, please consider attending the Sixth Combined Workshop on Interactive and Urgent High-Performance Computing. Keynote by Alan Chalker from OSC, talking about Open OnDemand.

Good morning #HPC, Good morning #SC25

The "Elevators" are a technical marvel, given they were built in the 1960s. Surely one of the strangest elevators on the planet.
