ThinLinc is available in a beta version for #Arm64, via the ThinLinc download page: www.cendio.com/thinlinc/dow... The beta was tested on Raspberry Pi, NVIDIA DGX Spark and Ampere VMs in Azure. Looking for other testers in #HPC and #HPCDesktop use cases.

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.

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

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 😎)

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?

Robert Henschel @roberthenschel.bsky.social · 23/12/2025

"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.

Robert Henschel @roberthenschel.bsky.social · 04/12/2025

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.

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.

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.

Robert Henschel @roberthenschel.bsky.social · 12/10/2025

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! 🤯

Robert Henschel @roberthenschel.bsky.social · 06/10/2025

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. 😀

010

Robert Henschel @roberthenschel.bsky.social · 29/09/2025

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.

Robert Henschel @roberthenschel.bsky.social · 23/09/2025

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.

Robert Henschel @roberthenschel.bsky.social · 15/09/2025

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...

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.

020

Robert Henschel @roberthenschel.bsky.social · 25/08/2025

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?!

120

Robert Henschel @roberthenschel.bsky.social · 19/08/2025

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.

Robert Henschel @roberthenschel.bsky.social · 25/07/2025

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.
