Multi-Level Local SGD for Heterogeneous Hierarchical Networks
Timothy Castiglia, Anirban Das, Stacy Patterson
We propose Multi-Level Local SGD, a distributed gradient method for learning a smooth, non-convex objective in a heterogeneous multi-level network. Our network model consists of a…
Skedulix: Hybrid Cloud Scheduling for Cost-Efficient Execution of Serverless Applications
Anirban Das, Andrew Leaf, Carlos A. Varela +1
We present a framework for scheduling multifunction serverless applications over a hybrid public-private cloud. A set of serverless jobs is input as a batch, and the objective is t…
A Hierarchical Model for Fast Distributed Consensus in Dynamic Networks
Timothy Castiglia, Colin Goldberg, Stacy Patterson
We present two new consensus algorithms for dynamic networks. The first, Fast Raft, is a variation on the Raft consensus algorithm that reduces the number of message rounds in typi…
Performance Optimization for Edge-Cloud Serverless Platforms via Dynamic Task Placement
Anirban Das, Shigeru Imai, Mike P. Wittie +1
We present a framework for performance optimization in serverless edge-cloud platforms using dynamic task placement. We focus on applications for smart edge devices, for example, s…
Diffusion and Consensus in a Weakly Coupled Network of Networks
Yuhao Yi, Anirban Das, Stacy Patterson +2
We study diffusion and consensus dynamics in a Network of Networks model. In this model, there is a collection of sub-networks, connected to one another using a small number of lin…
