📝 Summary

Summary by CodeRabbit

• Tests
  • Updated locality-domain test expectations for devices with a single cached domain. Domain IDs are still checked on all devices, while the localized flag is checked only when multiple cached domains are present.

The locality-domain test now checks the localized flag only when the device has more than one cached domain. It retains the unconditional domain ID check.

Changes: Locality-domain test

Layer / File(s)	Summary
Conditional localized assertion libcudacxx/test/libcudacxx/cuda/ccclrt/device/logical_device.c2h.cu	The test checks localized only when domains.size() > 1. The domain ID check remains unconditional.

Priority: ⬇️ Low

Change: Other

Merge Risk: ⚪ Minimal · up to 20380

This adjusts a test expectation for single-domain devices while retaining the domain-ID check. No actionable merge-blocking risk is evident.

1. MatX SAR backprojection narrowing conversion rejected by NVCC · 1 job

Explanation: MatX main at d2489fd6736bcf3bc3e224c8d11aa0857a9d0b81 passes a wider arithmetic result to the float-only __sincosf intrinsic; NVCC 13.4 promotes the narrowing diagnostic to an error because MatX builds with all warnings as errors. The same line breaks its SAR test, benchmark, and example, while the PR changes only a libcudacxx logical-device test and does not intersect this code.

Diagnose the MatX SAR backprojection build at commit d2489fd6736bcf3bc3e224c8d11aa0857a9d0b81 under CUDA 13.4/GCC 14. Reproduce narrowly by compiling the test_00_transform_SarBp target with the flags used by ci/matx/build_matx.sh, then inspect the types of phase_correction_partial and w at include/matx/kernels/sar_bp.cuh:777. Implement the intended explicit fp64-to-fp32 conversion before calling __sincosf—for example, compute a named float argument with an explicit cast and pass that value—while preserving the desired multiplication precision. Apply the fix upstream in MatX, or temporarily pin CCCL's MatX CI to a verified good/fixed revision if an upstream patch cannot be consumed immediately. Validate the SAR test, benchmark, and example targets with warnings treated as errors.

2. cuOpt incompatible with RMM 26.12 stream API · 1 job

Explanation: cuOpt main at 729b27a4bce83046d5626901ee1ca84013cad210 is compiling against RMM 26.12 but still calls removed or changed stream interfaces, producing repeated .view() failures and a missing cuda_stream_default symbol. This is an external dependency-version mismatch unrelated to the libcudacxx test-only PR diff.

Evidence:

2026-10-15T00:43:06.8808592Z /home/coder/cuopt/cpp/src/pdlp/distributed_pdlp/shard.cu(33): error: class "rmm::_RMM_26_12::cuda_stream" has no member "view"

Failure group: cuOpt incompatible with RMM 26.12 stream API
Affected jobs:
- Build RAPIDS (optional) / cuopt: https://github.com/NVIDIA/cccl/actions/runs/38661035706/job/116182200920

Reproduce the cuOpt build at commit 729b27a4bce83046d5626901ee1ca84013cad210 against the exact RMM 26.12 headers selected by the CUDA 13.3 RAPIDS environment. Inspect those installed headers to identify the supported conversion/accessor for rmm::cuda_stream and the supported representation of the default stream. Update every affected cuOpt call site to the current RMM API: pass or explicitly convert cuda_stream objects as required by each RAFT/RMM function, and replace rmm::cuda_stream_default with the supported default-stream construction or accessor. Do not perform a blind textual replacement; verify each callee's expected stream type. If cuOpt main is intended for a different RAPIDS dependency branch, instead align the cuOpt and RMM branch/package pins in the third-party CI configuration. Compile the affected PDLP, feasibility-jump, and gRPC objects first, then run the focused cuOpt build-all validation under CUDA 13.3.
