Machine learning is, of course, a massive market and everybody’s focus.
But, does AMD just own the whole HPC stack at this point? (Or would they, if the software was there?).
At least the individual nodes. What’s their equivalent to Infiniband?

- OneDeuxTriSeiGo 1y agoIt's also worth noting Ultra Ethernet isn't just an AMD thing. The steering committee for the UEC is made up of basically every hardware manufacturer in the space except Nvidia. And of course Nvidia is a general contributor as well (presumably so they don't get left behind). https://ultraethernet.org/ https://ultraethernet.org/

- wmf 1y agoCray Slighshot is even faster than Infiniband. Now that Nvidia is removing FP64 I assume AMD will have 100% of the HPC market until Fujitsu Monaka comes out.
- latchkey 1y agoWithin the node (gpu to gpu), it is infinity fabric. Externally, it is 8x400G NICs, which is the limitation of PCIeV5 anyway. We had a guy training SOTA models on 9 of our MI300x boxes just fine. Networking wasn't the slow bit.
