UbiTrack: A Layout-Robust Neural System for Device-Free WiFi Tracking

Neural network-based device-free Wi-Fi tracking achieves superior accuracy over theory-driven approaches, yet its practical utility is severely limited by poor generalization across different device layouts. Existing models implicitly learn site-specific correlations, necessitating labor-intensive data recollection and...

Scaling Unmodified Multithreaded Applications with Elastic CXL-based Distributed Shared Memory

While CXL presents a promising hardware substrate for Distributed Shared Memory (DSM), seamlessly scaling multithreaded applications across multiple nodes remains a formidable challenge. Existing CXL-based DSMs fall short: they require manual code modifications to share non-heap data, employ rigid data placement polici...

AsymSpec: Efficient Cloud-Edge Speculative Decoding over Asymmetric Networks

This work presents AsymSpec, which addresses uplink-gated verification and invalid dependent work with two corresponding mechanisms, and shows that AsymSpec delivers 2.82-28.03$\times the output-token throughput of the strongest baseline.
