Parallel Sampling of Diffusion Models
by Andy Shih, Suneel Belkhale, Stefano Ermon, Dorsa Sadigh, Nima Anari

ParaDiGMs accelerates sampling of diffusion models without sacrificing quality by running denoising steps in parallel. ParaDiGMs is most useful when sampling with a large number of denoising steps on multiple GPUs, giving a 2-4x wallclock speedup.
