 # Dask4DVC - Distributed Node Exectuion
 [DVC](dvc.org) provides tools for building and executing the computational graph locally through various methods. 
 The `dask4dvc` package combines [Dask Distributed](https://distributed.dask.org/) with DVC to make it easier to use with HPC managers like [Slurm](https://github.com/SchedMD/slurm).
