Compare data, tensor, pipeline, and context parallelism using memory, communication, and failure boundaries.
Separate model routing from expert placement, and calculate the memory and communication each layout needs.
Calculate memory per token, allocate complete blocks, and distinguish snapshot capacity from room to finish.
