Earlier quoted context omitted.

That Telsa owners can use their cars to make money while they are working as robo taxis -let's just say he vastly underestimates effort it takes to make progress - FSD is not there yet.

Vaporware assumes it will never happen. Is that the case you think or is it that he was vastly over optimistic? Very likely the latter.

They will get there at some acceptable point but not with the tech in current Tesla's - the current compute module will need to be replaced - think they showed off HW 4 in lieu of HW 3.

Sucks to be if you paid the early bird fee for it.

n00b questions from someone just beginning to get interested in HPC I see mention of using this supercomputer for training models. Is that the only purpose? What other types of things do orgs usually do with these supercomputers? Are there any good boots-on-the-ground technical blogs that provide interesting detail on day-to-day experiences with these things?

As opposed to keeping all of your servers independent of each other, super computers are used any time you want to pretend the entire computer is one computer.

In other words, they're used when you want to share some kind of state across all of the computers, without the potential overhead of communicating to some other system like a database.

Physics simulations and like, molecular modeling come to mind as common examples.

In the case of ML training, model parameters and broadcasting the deltas that get calculated during training are that shared state.

FSD is currently in the quantum valley of product development: it is both vaporware and a shipping product.

I understand that the H100 is NVidia's leading edge chip, but can someone let me know if 10K is considered to be a big cluster? I've never worked inside one of the leading edge AI companies like OpenAI, Google, Microsoft or Meta. Is this comparable to what they would work with? My first guess is that it seems much smaller. And if you are running many parallel training jobs then you are getting about 1,000 chips at mo…

10k H100 chips is considered a very large cluster. The third fastest supercomputer in the world is Microsoft’s eagle with 14k H100s https://www.top500.org/lists/top500/2023/11/

Ah, gotcha, so the fact that its 10,000 chips for one dedicated cluster that makes it large, as opposed to Azure which has an order of magnitude more GPUS but rents many of those out.

Agreed, feel bad for anyone that did that. Hopefully lessons learned on not making huge purchases based on some revolutionary future tech that isn’t fully baked yet / all problems solved for. Definitely an area I would never want to be an early adopter in.

The most powerful listed supercomputer has 37,888 Radeon GPUs, so in the same order of magnitude.

Interesting choice of words... I take you work for OpenAI? :) How large is their/'your' cluster? Probably the biggest in the world by now..

Parent is almost certainly talking about Frontier, the supercomputer with the US Department of Energy[0].
