Not a 32 core computer. It's 8 4-core SoCs with independent storage connected by a 5 Gbps network switch. Not a useless machine (it's a cheap way to buy lots of DRAM bandwidth, I'll note), but not what the headline is selling as.

With the right software and if you don't look it from too close, it can be considered a single computer.

We've been doing things like these for decades.

Yes, I'm that old.

Did the headline change? The one I see now just says that it's 32 cores in a tiny box, not that it's one machine specifically.
The site itself is a little misleading. It says "The Baserock Slab is a multi-processor server". To me, calling something a multi-processor server implies that a single OS instance has access to all the hardware. Instead, this is eight independent systems in a single chassis. Which is still awesome for that suggested use cases, such as an ARM build system.
I didn't say it was factually incorrect, I said (implied, I guess) it was misleading. You're seriously saying you read that and understood it meant 8 (!) distinct machines on one board?
I read it and understood it was a lot of cores in a small box. I presumed they weren't actually one machine, yes; but I didn't feel the headline was trying to imply anything either way.
So each quad-core SoC appears to the outside world as its own system and only communicates via Ethernet? Not useless at all, but it's not clear how the SoCs are presented.
Yeah, it's eight individual systems with two very fast Ethernet links to an on-board managed switch.
