Thanks - I had read those papers but hadn't realized the neural nets
were run on GPUs.

This was very useful, thanks!

One of the comments, on the above blog, questions that 10x speed-up:


Confirmed here:

So, currently they use a 32-bit float, rather than a 64-bit double, but
will reduce that to 16-bit to get a double speed-up. Assuming they've
been listening to customers properly, that must mean 16-bit floats are
good enough for neural nets?
