Tensor parallelism requires extremely high inter-node bandwidth (typically relying on NVLink or InfiniBand) and is unsuitable for high-latency public network environments; pipeline parallelism vertically partitions by layer, has lower peak bandwidth requirements, and is better suited for heterogeneous network environments.
