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

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...

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.

Going to #SC25 and interested in interactive and urgent #HPC? You should come to our workshop! Friday, 9 to 1 in room 260!

I am excited to give a talk at Oak Ridge National Laboratory next week. I will be talking about my favorite topic, making #HPC systems easier to use and providing researchers with tools that help them get more science done. #HPCDesktop.

I was asked if my #HPC object browser can run in JupyterLab. So Cursor/Sonnet 4.5 got to work and transformed the QT5 app into a JupyterLab extension. I am really impressed, most of the UI features work the same way in JupyterLab as they do in the QT5 version. It took not even an hour to convert! 🤯

After showing last week (bsky.app/profile/robe...) how to monitor job resources in #Slurm, the logical next step is to enable job submission. The video shows how to submit an interactive job in any partition by simply right-clicking the partition. The #HPC object browser is evolving nicely. 😀

I integrated a tool that shows resource usage of running #Slurm jobs, if you are allowed to ssh into the running job. It’s not a core part of the #HPC object browser, but seems pretty useful, especially for “new to HPC” folks. Short demo video below.

I added an object-class-specific details view to the #HPC objects browser. The view is customizable with templates and can pull in instance attributes of objects. (HTML + Jinja2). Development is progressing nicely and it's fun to explore this! 😊 Here is a video showing #Slurm partitions and jobs.

Here is a short video on how to get started with the #HPC object browser and the #Slurm provider. I am looking for feedback how the tool works in your environment. Give it a try and let me know. github.com/RobertHensch...

I ran across the TU Dresden Campus today, beautiful! @tudresden.bsky.social

Continuing the modeling/visualizing of #HPC objects. The video shows how to group objects by their properties. The example are #Slurm jobs, but this is a generic capability of the browser. It works with any property of any object. Groupings show in the breadcrumb bar for easy navigation and history.

Following up to last weeks post (bsky.app/profile/robe...), here is a video of the #HPC objects that I modeled: directories (Home, Scratch, Project), batch queues/partitions and jobs, software modules. This is not a mock-up, its a live view of the system! What other objects can you think of?!

I played with modeling an #HPC center as a collection of objects. Then I used Cursor to create a prototype app. Data providers running on a login node and the browser can run on a laptop or an #HPCDesktop. Blows my mind how fast I can explore ideas thanks to coding with LLMs.

I am exploring the topic of graphical file browser/managers for #HPC environments. If you have strong feelings on the usefulness/futility of such tools for HPC "end users", I would welcome your feedback or pointers to resource. Please reach out! Thank you.

I do miss #ISC25, but this is a pretty good excuse... 😎

Announcing @bsc-cns.bsky.social as 1st ever European host of #HPC Leadership Training Institute - Sept 2025 - the highly regarded & impartial 3-day class for current or future HPC leaders on strategy, procurement, technology evaluation, cost/risk/value models, etc. www.linkedin.com/posts/andrew...

Bye bye Boston, it was a great weekend!

Feeling great! Walking very slowly... 😎

That was fun!

Anyone else feeling great? 😂

I think I am getting the hang of this...

Athlete's village in Hopkinton. A bit more than an hour and I will be on my way.

It's getting real, in line for the bus to Hopkinton.

Good morning Boston. This looks like a great day for a run...

Not sure I will look this relaxed tomorrow when I cross the finish line...

Final shake out run. Looking good for tomorrow!

Good morning Boston! One day to go...

This is really happening...
