Distributed-training guide argues GPU wiring matters as much as strategy

A new distributed-training piece examines how GPU wiring affects large-scale AI training. The analysis looks at approaches such as DDP, FSDP, and ZeRO while emphasizing that physical interconnects can determine how well a strategy performs.

The point is practical for teams scaling model training: software choices do not operate in isolation from cluster topology. Poor communication paths can erase the benefits of otherwise strong parallelization methods.

As more organizations train and fine-tune models, infrastructure literacy around GPU layout is becoming a core engineering skill.
