GPU Ring Communication: Data Segment Distribution Pattern

In an iteration, each GPU sends a segment to the next GPU:

– GPU1 sends a₁ to GPU2, where it is added to b₁
– GPU2 sends b₂ to GPU3, where it is added to c₂
– GPU3 sends c₃ to GPU4, where it is added to d₃
– GPU4 sends d₄ to GPU1, where it is added to a₄

Algorithm 1) All-reduce

An obvious way is to send the gradients from one device to all other devices to synchronize them.

But this utilizes high bandwidth.

If every GPU has “N” elements and there are “G” GPUs, it results in a total transfer of G*(G-1)*N elements 👇 pic.twitter.com/cxqdc3PszF

Increasingly, the findings of controlled experiments go much further: doctors with off-the-shelf AI outperform those without in diagnostics… but AI alone outperforms doctors. Harder to know what to do with that. What systems or interfaces will result in better human-AI teams?

95% of the new "AI experts" on LinkedIn never experienced the good old days when some people wanted to put Jupyter Notebooks into production. That was the real prehistory of AI: explaining to managers that, well, no, we don't do that… Just because MNIST runs.
