Concurrency is a form of non-strict evaluation: the exact order of operations is unpredictable. The multiprocessing package introduces the concept of a Pool object. A Pool object contains a number of worker processes and expects these processes to be executed concurrently. This package allows OS scheduling and time slicing to interleave execution of multiple processes. The intention is to keep the overall system as busy as possible.
To make the most of this capability, we need to decompose our application into components for which non-strict concurrent execution is beneficial. The overall application must be built from discrete tasks that can be processed in an indefinite order.
An application that gathers ...
