Attention

The vector search and clustering algorithms in RAFT are being migrated to a new library dedicated to vector search called cuVS. We will continue to support the vector search algorithms in RAFT during this move, but will no longer update them after the RAPIDS 24.06 (June) release. We plan to complete the migration by RAPIDS 24.10 (October) release and they will be removed from RAFT altogether in the 24.12 (December) release.

Random State

#include <raft/random/rng_state.hpp>

namespace raft::random

struct RngState

The RNG state used to keep RNG state around on the host.

Public Members

GeneratorType type = {GeneratorType::GenPC}

The generator type. PCGenerator has been extensively tested and is faster than Philox, thus we use it as the default.
