Cross-View Sequential Visual Localization with Spatio-Temporal Context Modeling for Autonomous Driving
Jiaping Wang, Shaobo Li, Zhen Wang
Continuous and reliable localization is essential for autonomous driving. Cross-view visual localization matches ground images with satellite maps, providing complementary localiza…
RAGPerf: An End-to-End Benchmarking Framework for Retrieval-Augmented Generation Systems
Shaobo Li, Yirui Zhou, Yuan Xu +5
We present the design and implementation of a RAG-based AI system benchmarking (RAGPerf) framework for characterizing the system behaviors of RAG pipelines. To facilitate detailed…
SkyByte: Architecting an Efficient Memory-Semantic CXL-based SSD with OS and Hardware Co-design
Haoyang Zhang, Yuqi Xue, Yirui Eric Zhou +2
The CXL-based solid-state drive (CXL-SSD) provides a promising approach towards scaling the main memory capacity at low cost. However, the CXL-SSD faces performance challenges due…
ByteFS: System Support for (CXL-based) Memory-Semantic Solid-State Drives
Shaobo Li, Yirui Eric Zhou, Hao Ren +1
Unlike non-volatile memory that resides on the processor memory bus, memory-semantic solid-state drives (SSDs) support both byte and block access granularity via PCIe or CXL interc…
