Re: [Numpy-discussion] speeding up operations on small vectors

So it's the dot function being called repeatedly on smallish arrays that's the bottleneck? I've run into this as well. See this thread [1]. (...)

Thanks for the links. "tokyo" is interesting, though I fear the intermediate matrix size regime where it really makes a difference will be rather small. My concern is in really tiny vectors, where it's not even worth to call BLAS.

I'd be very interested to hear if you achieve a great speed-up with cython+tokyo.

I try to solve this problem in some way or other. I'll post here if I end up with something interesting. Christoph
