Workshop: How Far is Too Far? Interconnect Latency and Distributed AI Training
Artificial intelligence? Generalized intelligence? Superintelligence? Delivering on this promise requires ever larger models, enormous training datasets, and millions of GPUs. Distributed training enables workloads to be spread over large geographic regions, separated by hundreds or even thousands of kilometers. Novel networks are being introduced to interconnect these compute clusters, resolving power density problems, but introducing new challenges such as restricted bandwidth, network latency, transceiver complexity, and power dissipation.
