Good Morning #PEARC26

Let's talk about #HPCDesktops and ThinLinc at #HPC #PEARC26. I am thankful to Cambridge Computer for allowing us to exhibit at their partners pavilion.

Now happening at #ISC26 #HPC

Looks like #ISC2026 #HPC

A little zen on my way to Hamburg for #ISC2026 #HPC

Let's go! #ISC2026 is waiting..

Over the last months, I posted application demos for #HPC and the #HPCDesktop . If you are at #ISC26 and would like to connect, I would love to chat! I am in Hamburg all week. Please reach out via DM on LinkedIn, X or Bluesky, or send me email! I would love to get together over a coffee.

Yesterday I gave a short talk about building #HPCDesktops with ThinLinc at CUG 2026. I had a number of good conversations after the talk, and I am really enjoying the conference! #HPC #CUG2026

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

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 😎)

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

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

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.

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.

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. www.interactivehpc.com @larofeticus.bsky.social #HPC

Good morning #HPC, Good morning #SC25

Are you in St. Louis this week for #SC25? Don't forget that you can go up "in" the arch! A pretty unique experience you shouldn't miss! #HPC

Elias Werner and I explored what a software chatbot looks like on an #HPC Desktop. The goal was to explore the user actions enabled by a chatbot running as a native application. @scadsai.bsky.social is holding a SofaTalk at #SC25 booth 513 on Tuesday, 1pm to talk about LLMs and chatbots in HPC.

I published my first LinkedIn article, where I am reflecting on the #HPC Desktop and how I presented it at Oak Ridge National Lab two weeks ago. It even contains a call to action. 😁 If you are going to #SC25, I would love to chat about the #HPCDesktop. www.linkedin.com/pulse/secure...

Secure and Scalable: The Case for the HPC Desktop

In October 2025, I gave a talk about the HPC Desktop Concept at Oak Ridge National Lab. I had given a similar talk at the HPC-AI Advisory Council meeting earlier in the year and at the University of D...

I had an outstanding visit to ORNL last week to present the #HPC Desktop concept. Big thanks to Jeffrey Vetter, Pedro Valero-Lara and William F. Godoy for organizing and being great hosts! DM if you would like to learn more about the #HPCDesktop, happy to chat at #SC25 or Zoom.
