Spent a few months preparing the tech docs for DataEnclave, VAST's new confidential computing runtime. W/ help from VAST R&D, I learned how attestation etc worked well enough to describe and defend it. Short version: www.vastdata.com/blog/introdu... 15-pager: www.vastdata.com/resources/wh... #AI

Introducing VAST DataEnclave Confidential AI

VAST DataEnclave runs AI workloads in hardware-isolated environments, so proprietary models and sensitive data can meet on untrusted infrastructure.

I wrote this doc to explain KV caches and KV cache offloading many months ago. I found salespeople couldn't confidently tell when their customers might have a problem, because all the content online is straight marketing or way too in the weeds. blog.glennklockwood.com/2026/09/what...

Malaysia is allegedly evaluating Huawei's Ascend 910C for their sovereign AI buildout. If Malaysia picks Huawei over NVIDIA, it'd be the first big buy of these chips outside of China. Egypt also name-dropped as a nation being pursued by Huawei. www.freemalaysiatoday.com/category/hig...

The lack of shame some people have in copypasting prose straight out of Claude into Powerpoint is shocking. Were these people just recycling their students’ slides before, and now just tap a different source of material?

I recently upgraded to Claude Max and started using Opus 5 for exploratory analysis. If this is what the AI community things approaches "PhD-level capability," I don't know what to say. It's sloppy, inconsistent, and walks back conclusions at the lightest of questioning.

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.

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

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

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

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.
