So what do we actually do in the #HPC space? Yea I haven't figured it out yet either 😂 cloudhpc.news/cosplaying-a...

Time to start a fight on bsky #HPC Let’s talk about whether we should enable SMT/ HT cloudhpc.news/smt-ht-in-hpc/

The Nvidia DGX Spark is NOT as supercomputer. No more than your iPhone is. I wish reviewers would stop calling it that. I can't even take you seriously if start with that premise. Yea I said it. #HPC #Supercomputing

I'm have a weird problem on #AWS but only in eu-west-1 and eu-west-2. We have some code that automates VM instance creation and then connects to the instance via SSH. Was working fine globally last week. Now, any VM created in eu-west-1 or eu-west-2 is unresponsive. Can't SSH in to it.

If we're going to redo DC power cabling all over again why not do it right. Wouldn't it be cool to have a PoE style protocol but with wiring and connectors gauged for 1MW? Plug in a single cable into a rack. If the protocol negotiates everything is fine you get power, else it stays off.

I should try and remember to post this on here more regularly. Your weekly #HPC news with a dose of KPop Demon Hunters cloudhpc.news/quantum-81/

Are you trying to combine #AI with other #HPC workloads? Attempting business automation? Be curious to hear your take cloudhpc.news/ai-adoption-...

Can anyone tell me where I can find some HBv5? It allegedly exists according to this: learn.microsoft.com/en-us/azure/... but is rather absent from here: azure.microsoft.com/en-gb/explor... not sure if there's an az CLI command that could find it without listing all VM types in every region...

Title to this one is straight from @forbiddenunix.com 😁 Let’s talk more across #HPC there’s a surprising amount in common even where you wouldn’t expect it. cloudhpc.news/hpc-in-finan...

with @hpcwrangler.com a legit #hpc legend, it was a total blast my friend! www.linkedin.com/feed/update/... #hpc #cloud

Was a bit of an exciting week for large scale compute, #HPC and AI in the UK last week and more big news from Intel, Nvidia and Microsoft. Eek. cloudhpc.news/quantum-78/

Beyond the water that cools the servers, data centers indirectly contribute to water use through the electricity generation needed to power their operations. That indirect use often makes up 80%+ of the overall water use. spectrum.ieee.org/ai-water-usage #HPC #AI @spectrum.ieee.org

I know I’ve been promising this for a while and you’d be forgiven for thinking it wasn’t going to happen… but here it is. Chapter 2 of Intro to Supercomputing and #HPC cloudhpc.news/intro-to-hpc...

Today I have been mostly avoiding finishing the paper I’m supposed to be writing by attempting to do somersaults on the trampoline with the kids. And failing at that too. Meh. #HPC will have to wait a bit longer to find out how performance varies for throughout vs latency.

I have a stupid idea. I know it must be stupid because I think it may involve blockchain. But I need some help figuring out why it’s stupid exactly. Oh the fact that I know nothing about security and this is a security related idea also guarantees it’s dumb. Please tell me why. /1

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. 🧵

HPC Club goes to Bristol to talk about Isambard-AI Details and link to sign up here: hpc.club/events/2025-...

My office for today

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! 🥳

If you know you know 😁 @vsoch.bsky.social

sigh... another writer that doesn't have the first clue of the difference between HTC and HFT in FSI yet feels qualified to write an entire article on Gen AI and GPUs in FSI.... FFS... come talk to me if you want someone who actually knows instead. www.nextplatform.com/2025/07/24/f...

A question for all your digital nomads out there. I’m planning on spending a few weeks with the family around the French Alps but I need to be working remotely. What connectivity solutions have you used? We have a campervan and no fixed plans 5G? Starlink? (though that means supporting Elon 🤢)

#HPC benchmarks are always fun to talk about right? I don't even bash HPL in this one. cloudhpc.news/the-bi-modal...

If you were hoping people, especially you know the so called tech experts out there and self proclaimed kings of the hill, would be better at spotting supply chain attacks after the Jia Tan debacle well you’d be wrong.

I know I asked this before… but asking again in a bit more detail. Anyone put together a benchmark to measure system performance? cloudhpc.news/measuring-cl...

We really don’t talk about observability in #HPC enough!

I've had a bit of fun this weekend. www.linkedin.com/posts/hamza_...

Time for some Friday #HPC Fun cloudhpc.news/death-by-hpc/

Colour me impressed. I've been benchmarking some stuff recently... apart from the benchmark results, I captured power usage and CPU utilisation. Power was using Yakogawa WT310 and just its CSV output. CPU very basic and just using vmstat -t -S M and piping to a file. #HPC #Benchmarking

We’re hiring. Not HPC this time … cloudhpc.news/hiring-enter...

Anyone know of a distributed benchmark that runs under a scheduler? I.e the ability of the scheduler to optimally place workload would affect the score as well as the hardware? Yes I know this is a weird question.

I seem to have this on repeat at the moment. open.spotify.com/track/2eK1ZL...

an idea for how we communicate about where our expertise within HPC lies. a spidergram might work better? cloudhpc.news/hpc-expertis...

a hat tip to @redoakconsulting.co.uk for inspiring and building upon their blog post for this one cloudhpc.news/hpc-needs-to...

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!

#cats #catsofistanbul They’re everywhere

Let’s play where’s Hamza? Taking bets on who the HPC hero is too 😝 Don’t worry. It will be easier than figuring out who HPC Guru was! cloudhpc.news/hpc-is-like-...

Seeing developments like this in the K8 it’s no wonder I see more and more people trying to ditch classical HPC schedulers in favour of K8. Or trying to. This looks very applicable to a heterogeneous world of compute.

Here's my notes from ISC'25 in Hamburg: blog.glennklockwood.com/2025/06/isc2... #HPC

You know you really needed a break when you book some flights and then consumed by a sense of overwhelming relief 😊 Now I just have to make myself stop working

So at what point does the imposter syndrome stop exactly? Asking for a friend 👀…

At the risk of being wrong/ ostracised here’s another non conventional #HPC take… cloudhpc.news/isc25-ppp-ob...

A super quick take from me on one of the #ISC workshops I attended last week. mashed up with some info about #HPC Club later today. See you there? cloudhpc.news/flux-framewo...

Let’s have some fun Who did you want to meet at #ISC25 but didn’t? #HPC missed connections 😆

Catch up on ISC gossip and talk next generation schedulers…. Oh and your usual weekly #HPC news cloudhpc.news/quantum-64/

Still hate flying! Any #HPC people on the 0640 back to London ? No? No else mad enough to booked a flight this early. Sounds about right.

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!

Really good session on Flux Framework at #ISC25 just now. If you’re looking for a scheduler it should def be on your shortlist. And even if you’re not it’s one to keep an eye on. flux-framework.org or watch the excellent videos by @vsoch.bsky.social on YT #HPC

That’s a wrap at #ISC25 #HPC Thanks to everyone who made it possible. Non official gossip catch up at HPC Club on Wednesday 🙃
