Hierarchical all-reduce
WebAllReduce其实是一类算法，目标是高效得将不同机器中的数据整合（reduce）之后再把结果分发给各个机器。在深度学习应用中，数据往往是一个向量或者矩阵，通常用的整合则 … Weball-reduce scheme executes 2(𝑁𝑁−1) GPU-to-GPU operations [14]. While the hierarchical all-reduce also does the same amount of GPU-to-GPU operation as the 2D-Torus all …
Hierarchical all-reduce
Did you know?
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 … Webcollectives, including reduce, in MPICH [15] are discussed in [16]. Algorithms for MPI broadcast, reduce and scatter, where the communication happens con-currently over two binary trees, are presented in [14]. Cheetah framework [17] implements MPI reduction operations in a hierarchical way on multicore sys-
WebApart from the Ring all-reduce based operations [62], we include operations derived from hierarchical counterparts, which are 2D-Torus [46] and Hierarchical Ring all-reduce [71]. Web5 de jun. de 2024 · 1 Answer. There are some binaries for NCCL on Windows, but they can be quite annoying to deal with. As an alternative, Tensorflow gives you three other options in MirroredStrategy that are compatible with Windows natively. They are Hierarchical Copy, Reduce to First GPU, and Reduce to CPU.
WebTherefore, enabling distributed deep learning at a massive scale is critical since it offers the potential to reduce the training time from weeks to hours. In this article, we present BlueConnect, an efficient communication library for distributed deep learning that is highly optimized for popular GPU-based platforms. 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 ...
