Superconvexity of the Heat Kernel on Hyperbolic Space
Yongzhe Zhang
We prove a conjecture of Bernstein that the superconvexity of the heat kernel on hyperbolic space holds in all dimensions and, hence, there is an analog of Huisken's monotonicity f…
FastSV: A Distributed-Memory Connected Component Algorithm with Fast Convergence
Yongzhe Zhang, Ariful Azad, Zhenjiang Hu
This paper presents a new distributed-memory algorithm called FastSV for finding connected components in an undirected graph. Our algorithm simplifies the classic Shiloach-Vishkin…
Composing Optimization Techniques for Vertex-Centric Graph Processing via Communication Channels
Yongzhe Zhang, Zhenjiang Hu
Pregel's vertex-centric model allows us to implement many interesting graph algorithms, where optimization plays an important role in making it practically useful. Although many op…
Palgol: A High-Level DSL for Vertex-Centric Graph Processing with Remote Data Access
Yongzhe Zhang, Hsiang-Shang Ko, Zhenjiang Hu
Pregel is a popular distributed computing model for dealing with large-scale graphs. However, it can be tricky to implement graph algorithms correctly and efficiently in Pregel's v…
