CrossoverScheduler: Overlapping Multiple Distributed Training Applications in a Crossover Manner

no code implementations14 Mar 2021 Cheng Luo, Lei Qu, Youshan Miao, Peng Cheng, Yongqiang Xiong

Distributed deep learning workloads include throughput-intensive training tasks on the GPU clusters, where the Distributed Stochastic Gradient Descent (SGD) incurs significant communication delays after backward propagation, forces workers to wait for the gradient synchronization via a centralized parameter server or directly in decentralized workers.
