Surprised to see a solution so heavily focused on tiering to HDD for capacity now tier to…more HDD for capacity. Curious what Wasabi does that PanFS doesn’t (and vice versa) to make this pairing complementary.

I’m glad someone liked it! Hard needle to thread in crafting a technical plenary that is interesting, accessible, and thematic to “resilient roots.” Also relieved that my SDSC colleagues didn’t mind me spilling the tea on one of Gordon’s failures. #HPC #alittleAI

I am ready! Almost. #PEARC26

Another great addition to Utah’s amazing pro-human AI innovation ecosystem built on public-private partnerships.

🪶 Redtail, an AI factory for all of Utah, recently debuted on a list of the world's top supercomputers, ranking No. 159 for performance and No. 76 for energy efficiency. The system, managed by SCI’s Center for High Performance Computing at @utah.edu, supports statewide innovation. bit.ly/redtailrank

Surprising to see a software company go into the hardware business, selling an unusual 2U70 dual-controller flash server. It's hard to source flash these days, so there are strong market incentives to ship software on whatever hardware your customers can find.

We are now in the age of AI-generated conferences. Today’s keynote by Gropp prominently features distinctly Claude-generated plots; yesterday had an entire presentation delivered by an AI voiceover of slides. And slides are full of Claude design tells.

First time I’ve seen someone with a PhD actually predict that data centers in space will be a real thing. Granted, it’s a CS PhD, not a physical sciences one. #HPC #notreallythough

With Infinia gaining support for files, is there a reason for anyone to buy EXAScaler anymore? Why would someone choose Lustre over Infinia if Infinia seems to support everything that Lustre does but with enterprisey glitter? Curious to see how DDN positions these two lines. #HPC

ISC'26 recap

Last month was the 2026 ISC High Performance Conference in the beautiful (and sweltering) Hamburg, Germany. It was my fifth time att...

I somehow missed that China has developed its own implementation of InfiniBand, called ScaleFabric 400, to compete/supplant NVIDIA/Mellanox IB. Oddly enough, its manufacturer (Sugon) is not a member of IBTA though. en.eeworld.com.cn/mp/EEWorld/a... #HPC

The first domestically produced InfiniBand has been launched; real-world test data tells you just how powerful its performance is.-Electronics Headlines-EEWORLD

Interesting that C-DAC, whose indigenous Indian interconnect Trinetra is based around libfabric, opted to implement verbs support to make Lustre work instead of adopting Cray’s kfabric LND. #ISC26

1. General LLMs beat coding-specific models at writing Fortran, likely bc code models are overfitted to Python 2. This conf begins the age of Claude-generated pptx. Clear tells 3. My phone doesn’t like these #ISC26 projectors

Now happening at #ISC26 #HPC

This is the worst Jensen keynote ever

I can’t wait to hear what Jack Dongarra thinks about the future of #HPC at #ISC26’s closing keynote.

Dumb stuff that results in weird requirements in #HPC RFPs. Ultra dense GPU racks with all liquid requires unusual datacenter construction considerations. #ISC26

Ogawa-san is how I first came to know about China’s new exascale system a while ago, and I assembled a quick spec page a few weeks back (glennklockwood.com/garden/syste...). Notably has a BIG liquid cooled storage system (67 racks, 10 TB/s).

??? I was the lowest-level principal software engineer at microsoft and my parting annual liquid total comp started with a 4 when I quit. It was enough to support two of us on a single income in the Bay Area. Priced out of Redmond??? Sorry, but not very sympathetic.

this guy has been at Microsoft for 28 years, most recently as principal software engineer. he and his wife live in Redmond, Washington. they feel they're getting priced out of King County and are looking to sell their home and move somewhere cheaper www.seattletimes.com/business/loc...

It’s comforting to know that, at the macro scale, Lustre is pretty consistent at its strengths and weaknesses. I don’t think these are different from when I last used Lustre in 2022. From @adrianjhpc.bsky.social at the Lustre BOF in #ISC26

lol James Lin at #ISC26 #HPC

Is this because other energy companies don’t have multiple big supercomputers? Or because they don’t list them if they do? Fact that Exxon doesn’t go in as hard as ENI suggests either energy doesn’t need them

Andrew Jones (hpcnotes)@hpcnotes.bsky.social · last mo.

A lot of the focus on today’s latest #Top500 list will obviously focus on the new #1 system from China. But the other big story is that a single commercial user site (ENI) now has 2 #supercomputers in the top 10. I don’t think that has ever happened before? #HPc #ISC26

Hot #ISC26 tip: VAST is running free taxi service from the taxi stand in front of CCH to the SIDE hotel downtown and back. If you don’t feel like getting sweaty before/after an offsite meeting, I think anyone can hop in. Look for the city cabs with the VAST logo on the side.

The jump of LineShine over El Cap in efficiency is staggering. Suggests the benefit of balance and design for FP64-first over wedging FP64 into a socket whose chiplets were AI-first. LineShine’s poor HPL-MxP underscores. #ISC26 #HPC

“Heterogeneity is here to stay.” Also, “the new #1 system is homogeneous all-CPU.” #ISC26 #HPC

China’s back at the top of Top500. I guess the threat of not being allowed to buy US-designed chips is no longer a compelling reason not to submit top systems. Happy 250th, USA. #HPC #ISC26

20 minutes into the opening keynote at #ISC26 and Martin Schulz has managed to say AI only once; it’s changing everything, but let’s talk about quantum and #HPC instead. Impressive.
