Practical One-Round-Trip BFT Replication
Daniel Qian, Xiyu Hao, Jinkun Geng +4
As Byzantine Fault Tolerant (BFT) protocols are increasingly adopted for user-facing applications such as payments and smart contracts, it is crucial that they provide low latency.…
Probabilistic Fair Ordering of Events
Muhammad Haseeb, Jinkun Geng, Aurojit Panda +4
A growing class of applications depends on fair ordering, where events that occur earlier should be processed before later ones. Providing such guarantees is difficult in practice…
Beyond Lamport, Towards Probabilistic Fair Ordering
Muhammad Haseeb, Jinkun Geng, Radhika Mittal +3
A growing class of applications demands \emph{fair ordering} of events, which ensures that events generated earlier are processed before later events. However, achieving such seque…
Tiga: Accelerating Geo-Distributed Transactions with Synchronized Clocks [Technical Report]
Jinkun Geng, Shuai Mu, Anirudh Sivaraman +1
This paper presents Tiga, a new design for geo-replicated and scalable transactional databases such as Google Spanner. Tiga aims to commit transactions within 1 wide-area roundtrip…
Design and Implementation of a Scalable Financial Exchange in the Public Cloud
Muhammad Haseeb, Jinkun Geng, Daniel Duclos-Cavalcanti +5
Financial exchanges are migrating to the cloud, but the best-effort nature of the public cloud is at odds with the stringent latency requirements of exchanges. We present Jasper, a…
FlexPie: Accelerate Distributed Inference on Edge Devices with Flexible Combinatorial Optimization[Technical Report]
Runhua Zhang, Hongxu Jiang, Jinkun Geng +3
The rapid advancement of deep learning has catalyzed the development of novel IoT applications, which often deploy pre-trained deep neural network (DNN) models across multiple edge…
