Conversation
This PR adds a CAGRA search API and associated implementation for batching workloads involving a single query and multiple indexes (e.g. index segments built from one dataset by cuvs-lucene). This promotes GPU utilization for non-batched queries by parallelizing work over multiple CTAs, while minimizing the number of concurrent kernels for potential host-side parallelism. Addresses cuvs-lucene [issue 124](NVIDIA/cuvs-lucene#124), [issue 158](NVIDIA/cuvs-lucene#158), [issue 159](NVIDIA/cuvs-lucene#159), and cuvs [issue 2166](#2166). Associated cuvs-lucene PR: NVIDIA/cuvs-lucene#133. Authors: - James Xia (https://github.com/jamxia155) Approvers: - Corey J. Nolet (https://github.com/cjnolet) - Kyle Edwards (https://github.com/KyleFromNVIDIA) URL: #2035
