Group

The group function takes a list of signatures and creates a callable function to execute all of the signatures in parallel, then returns a list of all of the results as follows:

>>> from celery import group
>>> sig = group(multiply.s(i, i+5) for i in range(10))
>>> result = sig.delay()
>>> result.get()
[0, 6, 14, 24, 36, 50, 66, 84, 104, 126]
