Straggler-Aware Coded Polynomial Aggregation

Xi Zhong, Jörg Kliewer, Mingyue Ji

Coded polynomial aggregation (CPA) in distributed computing systems enables the master to directly recover a weighted aggregation of polynomial computations without individually de…

Fundamental Limits of Coded Polynomial Aggregation

Xi Zhong, Jörg Kliewer, Mingyue Ji

Coded polynomial aggregation (CPA) enables the master to directly recover a weighted aggregation of polynomial evaluations without individually decoding each term, thereby reducing…

Uncoded Download in Lagrange-Coded Elastic Computing with Straggler Tolerance

Xi Zhong, Samuel Lu, Joerg Kliewer +1

Coded elastic computing, introduced by Yang et al. in 2018, is a technique designed to mitigate the impact of elasticity in cloud computing systems, where machines can be preempted…

Dual-Lagrange Encoding for Storage and Download in Elastic Computing for Resilience

Xi Zhong, Samuel Lu, Joerg Kliewer +1

Coded elastic computing enables virtual machines to be preempted for high-priority tasks while allowing new virtual machines to join ongoing computation seamlessly. This paper addr…

Decentralized Uncoded Storage Elastic Computing with Heterogeneous Computation Speeds

Wenbo Huang, Xudong You, Kai Wan +2

Elasticity plays an important role in modern cloud computing systems. Elastic computing allows virtual machines (i.e., computing nodes) to be preempted when high-priority jobs aris…

Uncoded Storage Coded Transmission Elastic Computing with Straggler Tolerance in Heterogeneous Systems

Xi Zhong, Joerg Kliewer, Mingyue Ji

In 2018, Yang et al. introduced a novel and effective approach, using maximum distance separable (MDS) codes, to mitigate the impact of elasticity in cloud computing systems. This…

On the Information Theoretic Secure Aggregation with Uncoded Groupwise Keys

Kai Wan, Xin Yao, Hua Sun +2

Secure aggregation, which is a core component of federated learning, aggregates locally trained models from distributed users at a central server. The ``secure'' nature of such agg…

Coded Caching with Private Demands and Caches

Ali Gholami, Kai Wan, Hua Sun +2

Recently it was shown that the seminal Maddah-Ali and Niesen (MAN) coded caching scheme leaks the demand information of each user to the others. Many works have considered coded ca…
