What is the difference between model parallelism and data

WebApr 10, 2024 · Model parallelism suffers from a few shortcomings, compared to data parallelism. Some of these issues relate to memory transfer overhead and efficient pipelined execution. In this toy example I am purposefully running model parallelism on the wrong kind of workload. Model parallelism should in fact be used only when it’s … WebExample.
