> For the past few decades, building a datacenter has been a well-understood, predictable exercise in utility engineering. > In modern AI clusters, the network is no longer just infrastructure sitting beneath compute It always make me smile when someone is presenting these kind of topologies as "New", "Modern A.I" or anything remotely "Revolutionary". The HPC domain and any decent supercomputers have been doing RDMA networking centered around "all-to-all" and "all-reduce" operations for at least 3 fucking decades now. They are the main reasons supercomputers are almost always constructed around stupidly complex Torus or Dragonfly network topologies. MPI itself has these primitives defined from v1. The only difference now is that it switch from "This niche thing 3 nerds were using for weather simulations" to "this cool thing any hyperscaler NEED to have for *A.I*" |

in this context, that someone is an AI bot that spat out words.
