The passage around this formula
…Its cost is not bandwidth but idleness. GPipe’s contribution was to split each batch into micro-batches so that stages could work concurrently instead of waiting for a whole batch to traverse the pipeline [ 6 ] . With p stages and m micro-batches, the standard accounting gives a bubble fraction of . which says the only cure for pipeline idleness is more micro-batches in flight, and micro-batches cost memory. Narayanan and colleagues composed tensor, pipeline and data parallelism together,…
