Is there a reason you've chosen cython over numba and similar? Have you for example been able to wrap python with cython, then run borg inside python?

Hey James, I am currently using Cython to speed up our CALFEWS model, a large object oriented simulation model of water operations in the Central Valley.

I chose Cython over Numba, Pythran, PyPy, etc., because it is the most widespread and well established. Any Python code should work with Cython, whereas (to my understanding) the other tools are not compatible with all Python modules. I didn't want to invest my time in one of the other tools and then find out that something about CALFEWS makes it incompatible. However, my understanding is that Numba is getting better all the time, so I would be very curious to hear about your experience if you have tried it.

I haven't yet used Cython with Borg, but that's the goal. Cython lets you use C code with Python, or Python code with C. So I'm trying to speed up the model with Cython to make optimization more feasible, and then we should be able to use it with either the C or Python implementation of Borg.
