The papy package provides an implementation of the flow-based programming
paradigm in Python that enables the construction and deployment of distributed
workflows.
The NuMap package is a parallel (thread- or process-based, local or
remote), buffered, multi-task, itertools.imap or
multiprocessing.Pool.imap function replacment. Like imap it
evaluates a function on elements of a sequence or iterable, and it does so
lazily. Laziness can be adjusted via the "stride" and "buffer" arguments.
Unlike imap, NuMap supports multiple pairs of function and
iterable tasks. The tasks are not queued rather they are
interwoven and share a pool or worker "processes" or "threads" and
a memory "buffer".

The package is tested on Python 2.7.6
