Welcome to the MPIRE documentation!¶
MPIRE, short for MultiProcessing Is Really Easy, is a Python package for multiprocessing, but faster and more
user-friendly than the default multiprocessing package. It combines the convenient map like functions of
multiprocessing.Pool with the benefits of using copy-on-write shared objects of
together with easy-to-use worker state, worker insights, and progress bar functionality.
MPIRE currently only supports Linux based operating systems that support ‘fork’ as start method. Support for Windows is coming soon.
Faster execution than other multiprocessing libraries. See benchmarks.
Intuitive, Pythonic syntax
Easy use of copy-on-write shared objects with a pool of workers
Each worker can have its own state and with convenient worker init and exit functionality this state can be easily manipulated (e.g., to load a memory-intensive model only once for each worker without the need of sending it through a queue)
Progress bar support using tqdm
Progress dashboard support
Worker insights to provide insight into your multiprocessing efficiency
Graceful and user-friendly exception handling
Automatic task chunking for all available map functions to speed up processing of small task queues (including numpy arrays)
Adjustable maximum number of active tasks to avoid memory problems
Automatic restarting of workers after a specified number of tasks to reduce memory footprint
Nested pool of workers are allowed when setting the
Child processes can be pinned to specific or a range of CPUs
