Dynamic resource management in HPC is promising, but it only matters if it works under realistic supercomputer conditions.

If you care about practical dynamic resource management in HPC (not just theory), this one’s for you 😊

Does anybody else having issues with the #SC25 Wi-Fi?

@glennklockwood.com and @hpcnotes.bsky.social talking about about how we are moving from local/national data and computing infrastructures to global at the Vast breakfast. #SC25 #HPC #AI

A picture from the stage of the 5th session of #AI for #HPC Workloads #SC25

Starting from the closest to me are: John Lockman (Dell), @thoefler.bsky.social (ETH), the chair Kadidia Konate (NERSC), Terry Jones (ORNL)

We hope that everybody enjoyed the discussion.

We're celebrating 20 years of BSC #BSCx20
✋🏻Stop by booth G32 and leave your message on our Anniversary Wall 🖊️

Let’s celebrate together at #ISC25! 🥳

👉You can follow BSC activities at #ISC25 in our X account: x.com/BSC_CNS

That's from the other side! Thanks for helping to make this BoF bigger 🤩

In some cases, the LLM may perform better (especially when you are assigned a paper outside your main area of expertise). However, LLM's recommendations often tend to lean towards "accept with minor revisions".

✳Spots are limited, applications will be accepted based on robustness of the proposal & in order of submission

Warning: #SC24 attendees who picked up a #Slurm mug in their booth. It is not dishwasher safe :(

I've always wished, and asked, to have screen monitors for the panelists or BoF speakers. So you can see the presentation of your partners and have a better understanding of the afterward discussions with the audience. Regrettably, it has never been implemented ☹️ Hope you could do something 🤩

With that shape (narrow and long), I've walked more than in other editions. But it's huge

#2813 is running it :)

Still applicable for today?
