A Fast Bottom-Up Approach to Identify the Congested Network Links
TL;DR: This letter presents a new estimator for the prior probabilities that is computationally simple, being an explicit function of the measurement snapshots, and proves that the solution by the FBA is optimal.
Journal ArticleDOI
PEPesc: A TCP Performance Enhancing Proxy for Non-Terrestrial Networks
TL;DR: PEPesc as discussed by the authors is an open-source performance enhancing proxy (PEP) protocol for Nterrestrial networks using flying objects such as satellites, which has two distinctive features: first, it features adaptive packet-level forward erasure correction method called streaming coding (SC), and second, as packet losses are recovered by SC, the congestion control problem is simplified to rate control and local acknowledgement between entities based on bandwidth estimation.
Journal ArticleDOI
Legion: Automatically Pushing the Envelope of Multi-GPU System for Billion-Scale GNN Training
Jiecheng Sun,Li Su,Wen Shen,Zeke Wang,Lei Wang,Jie Zhang,Yong Li,Wenyuan Yu,Jingren Zhou,Fei Wu +9 more
TL;DR: Legion as discussed by the authors proposes a hierarchical graph partitioning mechanism that significantly improves the multi-GPU cache performance and builds a unified multiGPU cache that helps to minimize the PCIe traffic incurred by caching both graph topology and features with the highest hotness.
