Unverified70% confidenceFactExact time
The communication volume of the Ring-AllReduce algorithm is independent of the number of GPUs; the total amount of data sent and received by each node is fixed at 2(N-1)/N times the data size, making it theoretically the bandwidth-optimal AllReduce implementation.
