Andrey Prokopenko, Daniel Arndt, Damien Lebrun-Grandié, Bruno Turcksin · ACM Transactions on Mathematical Software · 2025
This article provides an overview of the 2.0 release of the ArborX library, a performance portable geometric search library based on Kokkos. We describe the major changes in ArborX 2.0 including a new interface for the library to support a wider range of user problems, new search data structures (brute force and distributed), support for user functions to be executed on the results (callbacks), and an expanded set of the supported algorithms (ray tracing and clustering).
