Time to publish the next book in "Stealing the network" series.

If we end up with a compute governance model of AI control [1], this sort of thing could get your door kicked in by the CEA (Compute Enforcement Agency). [1] https://podcasts.apple.com/us/podcast/ai-safety-fundamentals...

Looks like we're only a few years away from a bona fide cyberpunk dystopia, in which only governments and megacorps are allowed to use AI, and hackers working on their own hardware face regular raids from the authorities.

I find it baffling that ideas like "govern compute" are even taken seriously. What the hell has happened to the ideals of freedom?! Does the government own us or something?

Was it George himself, or a person working for a bounty that was set up by tinycorp? Also, a question for those knowledgeable about the PCI subsys: it looked like something NVIDIA didn't care about, rather than something they actively wanted to prevent, no?

He also documented his progress on the tinygrad discord

To be honest, I see summoning the threat of AGI to pose an existential threat to be on the level with lizard people on the moon. Great for sci-fi, bad distraction for policy making and addressing real problems.

The real war, if there is one, is about owning data and collecting data. And surprisingly many people fall for distractions while their LLM fails at basic math. Because it is a language model of course...

But the idea that this use of force is okay itself increases danger. It creates the situation that actors in the field might realize that at some point they're in danger of this and decide to do a first strike to protect themselves.

I think this is why anti-nuclear policy is not "we will airstrike you if you build nukes" but rather "we will infiltrate your network and try to stop you like that".

It means you can send data from the memory of 1 GPU to another GPU without going via RAM. https://xilinx.github.io/XRT/master/html/p2p.html

Is this really efficient or practical? My understanding is that the latency required to copy memory from CPU or RAM to GPU negates any performance benefits (much less running over a network!)

Peer to peer as in one pcie slot directly to another without going through the CPU/RAM, not peer to peer as in one PC to another over the network port.

Yes, the point here is that you do a direct write from one cards memory to the other using PCIe.

In older NVidia cards this could be done through a faster link called NVLink but the hardware for that was ripped out of consumer grade cards and is only in data center grade cards now.

Until this post it seemed like they had ripped all such functionality of their consumer cards, but it looks like you can still get it working at lower speeds using the PCIe bus.

> I'm not seeing the odiousness of the proposal. If bio research gets commodified and easy enough that every kid can build a new airborne virus in their basement we'd need raids on that too.

Either you create even better bio research to neutralize said viruses... or you die trying...

Like if you go with the raid strategy and fail to raid just one terrorist that's it, game over.

Freely flying through the sky on wings was scifi before the wright brothers. Something sounding like scifi is not a sound argument that it won't happen. And unlike lizard people we do have exponential curves to point at. Something stronger than a vibes-based argument would be good.

Commits are by geohot, so it looks like George himself.

I've seen him work on tinygrad on his Twitch livestream couple times, so more than likely him indeed.
