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
