Bug#817777: ITP: dask -- Dask is a simple task scheduling system that uses directed acyclic graphs (DAGs) of tasks to break up large computations into many small ones.
The plan is to have dask as an optional dependency for now. I should also package dask ASAP, though, because numerous other packages are waiting for it.
Bug#817777: Package name
The package name will probably be python-dask, not dask.
