Mm-hmm.

And the problem with that is you can't build that with, with a single switch or even a hierarchy of switches.

You have to build hierarchies of hierarchies of switches.

And so that means that when you communicate from one GPU to a different GPU, there are many different paths your traffic could take through that network, thousands of different paths your traffic could take through the network, because we build so many different switches in there.

There's, there's, you know, several thousand switches in one of these buildings.

Um, now that gives us an interesting problem, which is which path do you take from one place to the other? And if you, if you basically have the requirement that I want to be able to send from one GPU to another GPU as fast as possible, and I choose, say, a random path through the network, if I get lucky and nobody else chooses the same path, then great.

So to address this, you've been working on a method, a multi-path reliability connection.

The insight was basically that you have...
