High-Performance and Cache-Efficiency Adaptive Radix Tree for Disaggregated Memory

Disaggregated memory (DM) architectures enhance resource utilization and architectural scalability by separating computing and memory resources into distinct pools connected via high-speed interconnects, such as RDMA and CXL. Adaptive radix tree (ART) is a widely used range index known for its efficient support of vari...

Mario: Hierarchically Pipelined Approximate Nearest Neighbor Search on Computational Storage Devices

Scaling Approximate Nearest Neighbor Search (ANNS) to massive datasets exposes fundamental bottlenecks in PCIe bandwidth and random I/O. Computational storage devices (CSDs) promise to mitigate these constraints by enabling near-storage computation, but existing CSD-based ANNS engines employ only coarse-grained produce...
