A new research paper titled "Decentralized Gradient Descent: Bottleneck Regimes and Budget Complexity" explores the resource requirements for decentralized gradient descent (DGD) in distributed optimization. The study introduces a framework to analyze the communication and computation budgets needed to achieve specific accuracy levels, identifying distinct operating regimes dominated by factors like initialization, network connectivity, and noise. The paper proposes new quantities, the Gradient-Diversity-to-Network-connectivity Ratio (DNR) and the Gradient-to-Communication-noise Ratio (GCR), to guide optimal strategies and derive budget-complexity bounds.
