Web17 de jun. de 2024 · Performance: the ring all-reduce with p nodes need to finish \(2(p-1)\) steps (each step transfers the same amount of data). The hierarchical all-reduce with a group size of k only needs \(4(k-1)+2(p/k-1)\) steps. In our experiments with 256 nodes and a group size of 16, we only need to finish 74 steps, instead of 510 steps for using ring all ... WebBlueConnect decomposes a single all-reduce operation into a large number of parallelizable reduce-scatter and all-gather operations to exploit the trade-off between latency and bandwidth, and adapt to a variety of network configurations. Therefore, each individual operation can be mapped to a different network fabric and take advantage of the ... try by tems https://elvestidordecoco.com
