Neural network training.  Yes, it takes a long time.  Still, it's not the most tedious code I run.  I also do molecular-dynamics simulations with GROMACS, those runs can take over a week!

And as I replied to MRAB, my limiting code is within Numpy.  I've taken care to look for ways that I might have been using Numpy itself inefficiently (and I did find a problem once: fixing it tripled my execution speed).  But I would like to think that Numpy itself, since it is already a C extension, should be optimal.
