1 petaflop on a chip?? What is the catch?

Given that it's Nvidia, no Linux support. That's the catch.

All the AI software running on these data-centre chips is almost exclusively running on Linux.

I wish people would stop talking rubbish about NVIDIA's Linux support.

So the product naming for Nvidia's server-GPUs by compute power now goes: P100 -> V100 -> A100 -> H100 This is not confusing at all.

Isn't it based on the architecture name? https://en.wikipedia.org/wiki/Category:Nvidia_microarchitect...

Yeah it is, but unless you've memorised the history of Nvidia architectures it doesn't tell you which is the newer one

Fermi -> Kepler -> Maxwell -> Pascal -> Volta (HPC only) -> Turing -> Ampere -> Hopper (HPC only?) -> Lovelace?

That's a strange statement. The vast vast majority of these cards will be in systems running Linux.

I for one suffer deeply when I try to install the nvidia drivers on Linux. The website binaries _always_ break my system

Only the ppas from graphics-drivers work properly

My experience on windows is much more automatic and it never breaks anything. But I'd rather pay the price (installing on Linux) to avoid windows at all costs

Sounds like we need some new training methods. If training could take place locally and asynchronously instead of globally through backpropagation, the amount of energy could probably be significantly reduced.

Trying to reduce energy consumption for ML like this is so silly.

You just blew my mind. That did not occur to me, but it is obvious in retrospect.

From the nvidia page, > 80 billion transistors > Hopper H100 .. generational leap > 9x at-scale training performance over A100 > 30x LLM inference throughput > Transformer Engine .. speed .. 6x without losing accuracy So another monster chip - same size of the Apple M1-max thingy .. I guess it comes down to pricing. The A100 is already ridiculously expensive at $10K. They can this one at $50K and it would sell out?

You can buy A100s in a server today, a number of integrators will happily sell it to you.

Sure, but the way Nvidia names generations is far from obvious. It seems to be “names of famous scientists, progressing in alphabetical order, we skip some letters if we can’t find a well known scientist with a matching last name and are excited about a scientist 2 letters from now, we wrap around to the beginning of the alphabet when we get to the end, and we just skipped from A to H, so expect another wraparound in the next 5-10 years.”

Isn't this the norm? Only AMD started the trend of naming the uArch with Numbers as Zen 4 or RDNA 3 fairly recently. With Intel it is Haswell > Broadwell > ..... Whatever Lake.

Nvidia provides Linux drivers for their server chips.

Don't they provide them for their consumer cards too, just that it's a closed source binary blob?

And not just Linux: FreeBSD.
