I forked Olivier's example project to use the same infrastructure for
building conda binaries and deploying them to binstar, which might also be
useful for some projects.

Interesting. That explains why the divide-and-conquer reduction is much
more robust.
Thanks :)

Thanks for the clarification, but how is the numpy rounding directed?
Round to nearest, ties to even?

Just curious, as I couldn't find a reference.

BTW, why not throw an overflow error in the large float32 sum() case?
Is it too expensive to check while accumulating?
