Latest update (11-08 19:00): Google explains how Pathways coordinates large-model training with a single client

Overview: Google's developer blog explains Pathways, the distributed system it built to train its own large models including Gemini, and announces its General Availability on Google Cloud Platform. In the post, a single client describes the whole training job as a graph, and the distributed runtime places that work, moves tensors between devices, and keeps accelerators busy.

The post contrasts this with SPMD execution, in which lockstep collectives make pipeline stages and reinforcement learning loops harder to overlap, and a single machine failure restarts the run, according to Google's description.
