Summary

Track the coordinated migration of stream APIs and call sites from rmm::cuda_stream_view to CCCL's cuda::stream_ref. This propagates cuda::stream_ref through RMM containers and memory resources, RAFT resource and handle APIs, downstream C++ interfaces, Python/Cython bindings, benchmarks, tests, and documentation.

This migrates affected cuML C++ and Python/Cython stream interfaces and adapts CUDA, Thrust, RAFT legacy, and cuML raw-stream boundaries.

Depends on rapidsai/rmm#2372 and NVIDIA/raft#3129.

Tracked in rapidsai/build-planning#318.

Migrations

  • Pass cuda::stream_ref through stream pools, resource accessors, conditionals, and downstream APIs without converting to rmm::cuda_stream_view
  • Use cuda::stream_ref constructions for default/legacy/per-thread streams
    • rmm::cuda_stream_default ➡️ cuda::stream_ref{cudaStream_t{cudaStreamDefault}}
    • rmm::cuda_stream_legacy ➡️ cuda::stream_ref{cudaStreamLegacy}
    • rmm::cuda_stream_per_thread ➡️ cuda::stream_ref{cudaStreamPerThread}
  • Use .get() when calling an API that requires a raw cudaStream_t, including CUDA runtime, library, CUB, and legacy API boundaries (previously rmm::cuda_stream_view used value())
  • Use .sync() when synchronizing a cuda::stream_ref (previously rmm::cuda_stream_view used synchronize())
  • Update Cython declarations and call sites to pass stream references directly where supported

📝 Summary

Summary by CodeRabbit

  • Bug Fixes

    • Improved CUDA stream compatibility across GPU-accelerated algorithms, dataset generation, metrics, solvers, and manifold methods.
    • Improved interoperability with current CUDA and RAFT stream interfaces.
    • Preserved existing algorithm behavior and public APIs.

  • Tests

    • Updated GPU tests and benchmarks for current CUDA stream conventions.
    • Maintained validation coverage across supported GPU workflows.

Walkthrough

Changes

The pull request migrates CUDA stream handling across benchmarks, C++ algorithms, UMAP bindings, and tests. RAFT stream wrappers are unwrapped with .get(), and stream construction uses cuda::stream_ref.

CUDA stream migration

Layer / File(s) Summary
Benchmark stream construction
cpp/bench/sg/*		 Benchmarks use cuda::stream_ref for default and configured CUDA streams.
C++ algorithm stream propagation
cpp/src/*, cpp/src_prims/*		 CUDA, RAFT, RMM, Thrust, and time-series calls receive native CUDA stream handles.
UMAP stream contracts and bindings
cpp/src/umap/*, python/cuml/cuml/manifold/umap/umap.pyx		 UMAP stream parameters and Python binding calls use cuda::stream_ref or native CUDA streams.
Test stream migration
cpp/tests/*		 Test handles and asynchronous operations use the updated CUDA stream API.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 4b4a2

The stream API migration has unresolved stream-propagation issues that can cause operations to run out of order or on a stream different from the caller’s, potentially producing stale or racy results. Resolve these stream-boundary behaviors before merging.

0, preserving ordering with handle-stream operations.

handle->get_stream().get(), rather than the cuda::stream_ref wrapper; preserve
the existing handle initialization and stream behavior.
