Hierarchical all-reduce
Web17 de nov. de 2024 · Reducing the Number of Topics. Sometimes the Top2Vec model will discover many small topics and it is difficult to work with so many different topics. Fortunately, Top2Vec allows us to perform hierarchical topic reduction, which iteratively merges similar topics until we have reached the desired number of topics. Web15 de fev. de 2024 · In this paper, a layered, undirected-network-structure, optimization approach is proposed to reduce the redundancy in multi-agent information synchronization and improve the computing rate. Based on the traversing binary tree and aperiodic sampling of the complex delayed networks theory, we proposed a network-partitioning method for …

Figure 1 : The 2D-Torus topology comprises of multiple rings in horizontal and vertical orientations. Figure 2 : The 2D-Torus all-reduce steps of a 4-GPU cluster, arranged in 2x2 grid 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 ...
