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...
