Ray provides a scheduler for Dask ([dask_on_ray](https://docs.ray.io/en/latest/ray-more-libs/dask-on-ray.html)) which allows you to build data analyses using Dask’s collections and execute the underlying tasks on a Ray cluster. We have found with TAPE that the Ray scheduler is often more performant than Dasks scheduler. Ray can be used on TAPE using the setup shown in the following example."
