RT-HiSS: Ray Tracing Accelerated High Dimensional Vector Similarity Searches

RT-HiSS is proposed, the first exact GPU RT-core-based similarity search algorithm for high-dimensional datasets and introduces a two-pass approach to estimate an upper bound on result size, enabling efficient batching under GPU memory constraints with near-perfect load balancing.

Challenges in Scaling R-tree Spatial Search on Processing-In-Memory

The challenges of scaling R-tree spatial search on a commercial Processing-in-Memory (PIM) system are studied, and parallel host-side aggregation, efficient result handling, and query-aware DPU assignment for scalable PIM-based spatial search are motivated.
