Theano is also very interesting in regard of array computing, I've used it for very fast convolutional-neural-network training on GPU, but it can do many things (automatic symbolic differentiation, code generation, etc): http://deeplearning.net/software/theano/ http://deeplearning.net/software/theano/ I do really love the PyPy work for 'creating a faster Python'. I have a lot of scripts in Python that do parsing and then some work with numpy. These would hugely benefit from this.
