Thus, scheduling and executing [...] Meta and Malt at Google. All network management tasks require read and write to the network data in some form. Thus, we can abstract the network management workflows as changes to the network data and apply

However, as the complexity of models and datasets rapidly improves, network transmission has become a crucial factor in DNN training and cannot [...] data, how can we group jobs and place partitions to minimize JCT degradation and maximize GPU resource utilization? To answer this question, we first propose two theorems and provide the corresponding proofs [...] Training Investigators: Yiting Xia, Jialong Li, and Yiming Lei, in cooperation with Rui Pan (Princeton University), Zhiqiang Xie (Stanford University), and Binhang Yuan (ETH Zürich) Recent years have witnessed
