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

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.

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

I will drive on Saturday, the first ever SC I can easily drive to.

Let me know if you make it and we can get together for a coffee. If not, send me a DM and I am happy to schedule a call if you would like more info.

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.

Morning run sunrise today 😁

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 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.

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. 😀

To be perfectly clear, I would have killed for a tool like this when I got started in HPC way back. ;-) As a novice HPC user, wrapping your head around unattended job execution is hard and we "old folks" don't appreciate enough how hard it is.

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
