The whole website is genuinely unreadable / illegible with poor contrast.

yes, they should increase the font size as a first step.

I can do "ctrl + +" to increase the font, but it's still serif and low contrast, so I have to do "ctrl + A". Or better yet - press "reader view" on firefox.

It always make me smile when someone is presenting these kind of topologies as "New", "Modern A.I" or anything remotely "Revolutionary".

The HPC domain and any decent supercomputers have been doing RDMA networking centered around "all-to-all" and "all-reduce" operations for at least 3 fucking decades now.

They are the main reasons supercomputers are almost always constructed around stupidly complex Torus or Dragonfly network topologies.

MPI itself has these primitives defined from v1.

The only difference now is that it switch from "This niche thing 3 nerds were using for weather simulations" to "this cool thing any hyperscaler NEED to have for *A.I*"

This is the third time I've seen a website with this styling (serif, yellow and white on black). What's going on? Is it a template or some AI induced convergence?

I think it's Claude, yeah.

Datacenters are being built for AI. What happens when you remove the AI workload?

Don't get me wrong. I don't mind when some tech bros burn billions of venture capital & nothing much (?) comes out of it.

But those datacenters embody a lot of resources. Raw materials, complex/resource heavy manufacturing processes for IC's, servers, networking gear, etc etc.

I sure hope that doesn't go to waste when the AI bubble pops. Datacenter stuffed with AI optimized hardware any good for general engineering? Science projects? Weather prediction? Web hosting? ...??

Yeah, with only minimal guidance it's what you get out of claude. The colours and layout are pretty 'default'.

in this context, that someone is an AI bot that spat out words.

Rendering commercials, probably.
