RVANNS: Mixed-Precision Indexing and Locality-Aware Graph Traversal on RISC-V
Chengying Huan, Yudong Liu, Jianguo Wang +9
Approximate nearest neighbor search (ANNS) on CPUs is increasingly constrained by candidate-vector movement and decoding rather than peak arithmetic throughput. Although the RISC-V…
TIDE-MC: Two-Sided Interpolative Decomposition for Billion-Scale GPU Matrix Completion
Chengying Huan, Yubo Wang, Pinhuan Wang +11
Matrix completion supports large-scale recommendation and scientific computing, yet existing GPU solvers commonly assume that the observed matrix or its dense factors fit in device…
OrchANN: Hierarchical Orchestration for Skewed Out-of-Core Vector Search
Lizheng Chen, Pinhuan Wang, Shaonan Ma +9
At billion scale, approximate nearest neighbor search (ANNS) often becomes an out-of-core problem: the full vector collection and index structures exceed memory capacity, making qu…
Infernux: A Python-Native Game Engine with JIT-Accelerated Scripting
Lizhe Chen
This report describes Infernux, an open-source game engine that pairs a C++17/Vulkan real-time core with a Python production layer connected through a single pybind11 boundary. To…
