We used state machines to orchestrate a complex #HPC workload in #Kubernetes, and performed a Usability study across #Azure, #GoogleCloud, and #AWS with over 28K CPU and 256 GPU that resulted in over 26K datasets! dl.acm.org/doi/10.1145/... dl.acm.org/doi/10.1145/... Will be presented at #SC25.

Felt like noodle dancing today - throw back to 1999 and Lou Bega! 🙌 www.youtube.com/watch?v=VGQZ...

Belated Halloween Dance! 🎃 This is the first time that I've ever attempted this dance - I've seen it enough times that I got the general gist! But let's be real, it's terrible. 😄 I guess I don't care, because I had fun. Happy belated Halloween!

💪

And so it begins! Is lifting the bar hard for me? Yes. Is my shirt inside out? Also yes. 😂 Am I going to be consistent, and steadfast in my ability to manifest what I want in life? HELL yes. 👏

hey @rockylinux.org 👋 We have been getting 404s for some of the Rocky mirrors today (and recently) in our CI. Usually a rerun fixes it, but I wanted to make sure you were aware, and if there is a status page we could refer to for future issues? Thank you! 🙏

When things are hard, we remember that we are responsible for ourselves, and the outcomes of our choices. Today I chose strength, and to prove to myself that I am still the strongest person that I know. With time (and protein!) you will see it too. I embrace darkness, but I choose to be a light.

It's about time we think more about our job shape. This is something I'm really excited about for #FluxFramework! Have you ever thought about the implications of your flag choices for binding? I made a little tool today (WIP) that can detect (and then predict) topology (binding) down to PU.

Developer tip - taking the time to write comments for the next day. If you are a gerbil, a monster, a three toed sloth, or a goblin that will die alone, make sure to be honest with yourself about that. 🧌

Da nananana na na na na Batman! 🦇 I got a really challenging build environment working today (took 11 hours 🙃) and then... new track adventure! youtu.be/on8UcrpMy8c?... Dirt tracks are slippery, but you can still have a lot of fun! This was 4x400 (4 miles) of a relaxed pace, 3 warm up/cool down.

What did I do for the holiday weekend? 🤔 Biked around for 15 miles looking for a track. I didn't find one, so opted for paved paths instead. I didn't hit the pace I wanted, but in retrospect, this was a good effort! I ran this at noon on Saturday, when it was in the 90s. 😎

I like the message that I imbue this song with - life experience stays with us, and we choose to have strength. Often that means doing things that are hard. youtu.be/_XtLGncK1pk Today was my first interval workout - I found a dirt track and maintained a 5:20-6 minute mile pace for 12x300m. 💪

If you missed the #FluxFramework #HPC Innovation Center (HPCIC) Tutorial this year - have no fear! 🦸 We just posted the video online: youtu.be/EjA3qvbzzHU See the description for detailed timestamps. You can watch from the start, and I'll highlight 🖊️ sections of interest here. 🧵

About 76 miles of biking and running since Tuesday. 🌞 youtu.be/JxaVDqKoxa4?... There is so much beauty out there, and I feel so lucky to have the life experiences that I do. 🥰

For folks familiar with #SLURM- we are looking for a way to validate SBATCH directives. Slurm has --test-only but it does validation for flags *and* against a cluster, and they seem tied. In #Flux we can validate directives (via a directive parser) separately from resources (feasibility plugin). Ty!

This was 20 years ago. When we are young we often can't anticipate oncoming darkness. But we also can't anticipate our own resilience. What we come to realize with experience is that we are always in a mixture of light and shadow. It is a choice to not just see, but try to be a source of light. 🕯️

Flux Bird!? WHAT are you doing over there? 🦩 😅

Our #SC25 tutorial is up! 🎉 sc25.conference-program.com/presentation... I'm already excited! We will be co-presenting with #AWS and teaching you how to run #HPC workloads using #Kubernetes with the Flux Operator. And a taste of MuMMI, a workload with Ai/ML components. Hope to see you there! 🥳

"When you're the last one in the data center. " Me: I will do important, serious work. But also: youtu.be/OImn6x2VQu8?... 🦩

If you missed the #FluxFramework workshop and talks at #HPCKP, they are online! 🥑 Flux Framework Workshop: hpckp.org/talks/flux-n... The workshop includes an introduction to Flux, a talk on "Flux Environments," a hands on tutorial (actually a container adventure), music video and Jeopardy! 🌀

Please join us this Tuesday, July 1st, at 9am Pacific to learn about my team's work on "Cloud Usability for #HPC Applications" hosted by the #CASS software stewardship organization. Please message or email me for the calendar invite. Hope to see you there!

For the first time - user-space Kubernetes running under a Flux allocation on a production cluster. This is OSU and LAMMPS. This has been months of work and persistence. We got this working on an old kernel, and hugely strict security policy. Experiments and more details coming soon! 🥳

We’ve got a request for information out on where we want to take Livermore Computing and other #HPC centers in the next five years. hpc.llnl.gov/fg-hpcc-rfi Check it out and send us your thoughts.

Our post on compatibility using #OCI artifacts in the #Kubernetes blog is hot off the press! 📰 kubernetes.io/blog/2025/06... We are working on adding an exporter to #NFD for #HPC use cases. github.com/kubernetes-s... and planning experiments. If anyone has ideas, please share in the thread! 👇

For most that missed the #ISC25 Flux Framework Tutorial, we just posted our slides online: github.com/flux-framewo... Thank you to those that attended, and see you next time! 👋

The biggest lie I tell myself... "Just a little further..." 💙💚 youtu.be/7m9mkqpSzXM?...

These running socks and leggings are channeling #FluxBird! 🦩

If you missed the #FluxFramework tutorial at #ISC25 have no fear! My talk on Flux Environments is available for you to see! 🥳 youtu.be/erphMqHv1OE From containers to cloud virtual machines to #Kubernetes to #HPC Flux is a portability layer that meets the needs of emerging workflows. Let's dive in!

Found in the UCX config.log. I have so many questions... 👀

Running is an expression of determination. It is a fundamentally raw, physical experience that is private to the individual, and combines strength of body and mind. The discomfort is over if you just stop. But you decide not to. By deciding to endure the state of discomfort, you become stronger. 🧘‍♀️

The golden hour - when runs are ✨ and you fly! 💪

Having fun with #Kubernetes node feature discovery today. I present - the galaxy node explorer! converged-computing.org/aws-performa... Ultimately I am going to be doing a build matrix of different optimized builds and assessing them across types, and collecting #eBPF too. But for now, fun. 🚀

There are some great exercises that can be done with just a floor and socks. They will make you stronger. Most things in life are outside of our control, but we only get one shot. Let's be the strongest, kindest versions of ourselves possible. 🧦 youtu.be/wDBa6mbVrkg

Not able to attend #HPCKP25 this week? Have no fear! As promised, here is a bit of fun- a piece I like to call "Flux Time!" 🌀 youtu.be/N25GySogBeE This is a parody and creative piece written and performed by me. The lyrics here are my own words and do not reflect the views of my employer. Enjoy! 🥳

Coming to #ISC25? We have fresh content and several presenters to teach you about #FluxFramework. We hope to see you there! 👀

Excited about the #FluxFramework workshop coming up at #HPCKP25 in Barcelona? So are we! We have so much fun for you prepared... youtu.be/abbUbDXHGeM?... That's how we roll. 😎

#HPC (as a developer) predominantly means trying to find strategies to get around limitations. You can't be root or completely control the environment. Your kernel or compiler is old. On a good day, it's still a few hours to get up the point of working to innovate on the thing you are interested in.

Annual treat to myself of some new running gear! Both of these were on sale, and damn.🔥 There is something to say for clothing that is the epitome of strong elegance. #Nike - bravo! 👏

Amazing! I just built (in ~8 seconds) an interactive, graph-based scheduler emulator using Google Diffusion. codepen.io/vsoch/full/r... Excuse me, my head is exploding - this is so impressive! 🤯

Conference T-shirts are great, but they are typically Unisex that (for me) are too big somewhere. What to do? Find an elegant, "rocker tank" design that you love, make it, and rock it! Look at that beautiful #FluxFramework logo!😍 Rumor has it that it makes you run fast too. 😉

This one too, love this song! 🥰 youtu.be/VWClOrJ8DPE?...

How to dinosaur...! 🦖 Getting ready for an evening of running experiments! 💃 youtu.be/Ws4IrcUR1o4?...

Expectations do not often have the imagination to prepare you for the small, unexpected joys that pop up, once in a while. Expectations leave you satisfied, while unanticipated surprises move you deeply into a smile.

We need to look more critically at events like Salishan. It's not about the people that go or what they present, but rather the exclusion enforced in the design itself. It creates a disparity of information and opportunity that doesn't need to exist. It creates a culture with an in and out group.

After an initial study with a lot of manual orchestration to run #HPC apps in Kubernetes, I've redesigned the entire orchestration to be done with helm charts, and the experience is so pleasant! youtu.be/1VBxXIp8UlA?... Deploying an entire Flux cluster, running apps, and saving output: 1 command.

When we miss the people and places that we love, even before they are gone, it means that we have deep capacity to love. I used to be afraid of change, and losing everything that I loved - until I realized the love was within me, and I would decide to keep it. youtu.be/zccNTw-EjXk

If you want to learn about #FluxFramework (and have some fun) we are hosting our first workshop at the HPC Knowledge Portal annual meeting. Details at this link: hpckp.org/annual-meeti... Hope to see you there!

If you are interested in running #HPC apps in cloud with #Kubernetes "Trends for Pulling HPC Containers in Cloud" - a look at the ecosystem since 2014 and a robust pulling study - is published this week at Cloud Computing 2025. It is work driven by my love and curiosity of container technologies. ❤️

Good morning, and happy Monday folks! We have our first #FluxFramework dinosaur series notebook tutorial released this morning: youtu.be/5qT4eyO0thw We go through part 1 of the #HPCIC tutorial, basic commands for Flux, all in a #Jupyter notebook you can deploy too! 🥳

I appreciate the message of this song. It's about resilience, and choosing to work hard for balance even though you will eventually fall. youtu.be/QuE_Zr1NgFg?...
