PowerSGD: Practical Low-Rank Gradient Compression for Distributed Optimization

Thijs Vogels, Martin Jaggi

We study lossy gradient compression methods to alleviate the communication bottleneck in data-parallel distributed optimization. Despite the significant attention received, current compression schemes either do not scale well, or fail to achieve the target ...

Rethinking General-Purpose Decentralized Computing

Eleftherios Kokoris Kogias, Bryan Alexander Ford, Georgia Fragkouli, Enis Ceyhun Alp

While showing great promise, smart contracts are difficult to program correctly, as they need a deep understanding of cryptography and distributed algorithms, and offer limited functionality, as they have to be deterministic and cannot operate on secret da ...

Latency and Backlog Bounds in Time-Sensitive Networking with Credit Based Shapers and Asynchronous Traffic Shaping

Jean-Yves Le Boudec, Maaz Mashood Mohiuddin, Eleni Stai, Ehsan Mohammadpour

We compute bounds on end-to-end worst-case latency and on nodal backlog size for a per-class deterministic network that implements Credit Based Shaper (CBS) and Asynchronous Traffic Shaping (ATS), as proposed by the Time-Sensitive Networking (TSN) standard ...
