What is Allreduce
=====
The main methods provided by rabit are Allreduce and Broadcast. Allreduce performs reduction across different computation nodes,
and returns the result to every node. To understand the behavior of the function, consider the following example in [basic.cc](basic.cc).

the reduction operation will be a summation, and the result will become ```a = {1, 3, 5}```.
You can also run the example with different processes by setting -n to different values.
In order to make the library available for a wider range of developers, we decided to provide a python wrapper to our C++ code. Developers can now program rabit applications in Python! The same example as before can be found in [basic.py](basic.py):

Besides strings, rabit also allows to broadcast constant size array and vectors.
The counterpart in python can be found in [broadcast.py](broadcast.py). Here is a snippet so that you can get a better sense of how simple is to use the wrapper:
