Flux

Flux Framework is a suite of projects, tools and libraries for resource management and scheduling at High Performance Computing sites.

HPC-cloud computing just got a(nother) boost with @FluxFramework! Flux is now integrated into Kubeflow Trainer thanks to the hard work of @vsoch 🙌 https://t.co/qZE3Kb27uL

We are approaching #HPSF in Chicago and I am pumped! 🎉 Please come to my main track talk on converged computing and agentic workflows, our panel on emerging infrastructure, or the two tutorial sessions I am leading for the @FluxFramework community day. See you there!

[V @vsoch]

Coming to the #HPSF Conference in March? I hope you will attend the @FluxFramework sessions! 🌀 We will have a half day of talks, including an AI/ML Simulation Tutorial in #Kubernetes. All sing and dance with me now... "I like to Kube It, Kube It!"

From containers to cloud VMs to #Kubernetes to #HPC Flux is a portability layer that meets the needs of emerging workflows. Let's dive in!

For the first time - user-space Kubernetes running under @FluxFramework 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 + more details coming soon!🥳

[V @vsoch]

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

Good morning, and happy Monday folks! We have our first @FluxFramework dinosaur series notebook tutorial released this morning:

https://t.co/I3q22f5R5y

We go through part 1 of the #HPCIC tutorial, basic commands for Flux, all in a #Jupyter notebook you can deploy too! 🥳

Developers developers...! Do you want to contribute to @FluxFramework but don't know where to start? We got you! 😉 For this first tutorial learn how to bring up #vscode to build and run tests for flux-core and flux-sched "fluxion" https://t.co/wW2g8WHbYT using autotools & cmake.

[V @vsoch]

Let's kick off #SC24 with the first set (of many to come) of the @FluxFramework Tutorials - Dinosaur Edition! 🥑We didn't get an "official" tutorial, but guess what? This presented an opportunity - one to create a series of tutorials open to *everyone* across time and space. 🚀

I'm proud to share that my team is sharing early work to get userspace #Kubernetes running with an #HPC workload manager @FluxFramework on #AWS!

https://t.co/CKMLvZMao3

There is more to do, but I'm immensely proud of this work, and grateful for the people I get to work with.🥰

[V @vsoch]

I'm pleased to announce that our work on the @FluxFramework operator is published in @F1000Research! This is an example of #ConvergedComputing and was (continues to be) a joy to collaborate with @alculquicondor and @Itsuugo. https://t.co/gWSsXB2d7I. Let's do this more often! ❤️

[V @vsoch]

I've been doing experiments with custom schedulers, specifically running jobs with the @FluxFramework operator on #Kubernetes, and learning about not just the importance of the scheduler, but also the job design. https://t.co/7R7jsbCJoK. Let's talk about that a bit. 🧵
