Usage

Easy Multithreading

>>> import lox
>>>
>>> @lox.thread(4) # Will operate with a maximum of 4 threads
... def foo(x,y):
...     return x*y
>>> foo(3,4) # normal function calls still work
12
>>> for i in range(5):
...     foo.scatter(i, i+1)
-ignore-
>>> # foo is currently being executed in 4 threads
>>> results = foo.gather() # block until results are ready
>>> print(results) # Results are in the same order as scatter() calls
[0, 2, 6, 12, 20]

Easy Multiprocessing

>>> import lox
>>>
>>> @lox.process(4) # Will operate with a pool of 4 processes
... def foo(x,y):
...     return x*y
>>> foo(3,4) # normal function calls still work
12
>>> for i in range(5):
...     foo.scatter(i, i+1)
-ignore-
>>> # foo is currently being executed in 4 processes
>>> results = foo.gather() # block until results are ready
>>> print(results) # Results are in the same order as scatter() calls
