Project Summary
Task scheduling and blocked algorithms for parallel processing.
Dask is a flexible parallel computing library for analytics. Dask emphasizes the following virtues:
Familiar: Provides parallelized NumPy array and Pandas DataFrame objects
Native: Enables distributed computing in Pure Python with access to the PyData stack.
Fast: Operates with low overhead, low latency, and minimal serialization necessary for fast numerical algorithms
Flexible: Supports complex and messy workloads
Scales up: Runs resiliently on clusters with 100s of nodes
Scales down: Trivial to set up and run on a laptop in a single process
Responsive: Designed with interactive computing in mind it provides rapid feedback and diagnostics to aid humans
