Dask
For parallel computing in Python, Dask extends familiar tools to handle larger workloads.
About Dask
Dask is an open-source Python library for parallel computing. It works with familiar tools such as pandas, NumPy, and Xarray to process datasets that do not fit in memory on a single machine.
With Dask you can work with large DataFrames, run Python functions in parallel, process multi-dimensional array data in formats like HDF, NetCDF, TIFF, or Zarr, and train or run predictions with common machine learning libraries such as XGBoost. It can run on a laptop or be deployed on resource managers including Kubernetes, HPC job schedulers, and cloud services, and includes a dashboard to monitor computations.
Dask suits Python developers, data scientists, and researchers who already use pandas or NumPy and need to handle larger data or parallel workloads without changing languages.
