CUDA Top‑K Kernel Slashes Agentic RAG Retrieval Latency by Up to 8×
A custom CUDA Top‑K kernel stores the entire vector corpus in VRAM, eliminating the PCIe round‑trip that stalls agentic RAG retrieval. On a 7‑year‑old GTX 1080 it delivers up to 8.6× faster searches and deterministic microsecond tail latency, dramatically speeding up LLM‑driven pipelines.
