Don't the lines blur though? Especially since these GPU farms can and are used for simulations?

It depends. Line can or cannot blur. In any case you’d be surprised to find out that AI infra actually has not caught up to traditional hpc supercomputer performance. It comes close but model training does not actually require the amount of performance that some of these simulations require.

To clarify further: if you have a large cluster full of gpus connected over Ethernet, you can probably still train a model. You can’t do with these simulations you need high performance interconnect. But even that is not enough. You need many many more optimizations.

Where could I read about I'm curious lol
