 Building HNSW graphs, esp. with high dimensions and cardinality, is usually slow. If you have a NVIDIA GPU, then building HNSW based indexes can be sped up manifold. This is powered by the https://github.com/rapidsai/cuvs-lucene[cuVS-Lucene] library, a pluggable vectors format for Apache Lucene. It uses the state of the art https://arxiv.org/abs/2308.15136[CAGRA algorithm] for quickly building a fixed degree connected graph, which is then serialized into a HNSW graph. https://developer.nvidia.com/cuda-downloads[CUDA 13.0+] and https://jdk.java.net/archive/[JDK 22] are required to use this feature.

+=== GPU Acceleration (cuVS) Does Not Work in Solr 10.1
+
+[WARNING]
+====
+Vector indexing with the xref:query-guide:dense-vector-search.adoc#gpu-acceleration[GPU Acceleration] (cuVS) module (`CuVSCodecFactory` with `knnAlgorithm="cagra_hnsw"`) does not work in Solr 10.1 (refer SOLR-18556 for updates).
+Solr 10.1 upgrades to Lucene 10.4, and a cuVS-lucene (library which powers the GPU accelertion) library version compatible with Lucene 10.4 is not available as of Solr 10.1 release.
+
+If you use GPU acceleration for vector indexing, skip Solr 10.1 and stay on Solr 10.0.x.
+This is expected to be fixed in a subsequent Solr 10.x release.

 === v2 API
 Starting in Solr 10.1 it is no longer possible for users to disable the v2 API by use of the `solr.api.v2.enabled` system property, and the Solr server and tooling (`bin/solr`, Admin UI, etc.) will start using these APIs internally.
