- What happened
- NVIDIA cuML and cuVS 25.06 added multi-GPU support for UMAP's all-neighbors kNN graph construction, processing 870 GB of vectors in 8 minutes.
- Why it matters
- Data scientists and ML engineers working with massive datasets needing dimensionality reduction for visualization or feature extraction benefit from faster iterative exploration.
- Watch out
- Quality and speed depend on tuning knn_n_clusters and knn_overlap_factor parameters; memory usage scales with overlap factor and inversely with cluster count.
