How to Pick the Right Parallelism for 7B‑70B Models: DP, TP, PP, ZeRO & FSDP

This guide walks engineers through the memory, compute and bandwidth limits of training 7B‑70B models, compares data parallel (DP/DDP), tensor parallel (TP), pipeline parallel (PP), ZeRO stages and FSDP, shows how to calculate GPU memory, estimate communication overhead, configure each strategy, and avoid common pitfalls, enabling you to decide which parallelism to use on multi‑GPU or multi‑node clusters.
