Top: Likelihood evaluation times for catalogs with different numbers of events (each with 5000 PE samples) at a single hyperparameter space point, compared across different kernel algorithms. Solid curves show times on four Intel CPUs (2.0 GHz clock frequency), while dashed curves represent times on a single Nvidia A100 GPU. Bottom: Run times for a full affine-invariant MCMC fit, using the emcee sampler with 50 walkers, on 25 CPUs (left panel) or one GPU (right panel).
