Deprecate CUB iterators existing in Thrust #3304

bernhardmgruber · 2025-01-09T09:57:34Z

This P R deprecates the CUB iterators that also exist in Thrust. Uses of CUB iterators in tests and benchmarks are replaced by Thrust iterators. Uses of CUB iterators in the headers of CUB/Thrust are not replaced, since the Thrust iterator machinery does not compile under NVRTC. This will be addressed with #3480 for CCCL 3.0.

Fixes: #3261

SASS for cub.bench.reduce.arg_extrema.base did not change for SM86.

I love it when we remove stuff. Great Work!

bernhardmgruber · 2025-01-22T09:46:57Z

This is talking quite some effort to make all the Thrust iterator machinery compileable by NVRTC.

bernhardmgruber · 2025-01-22T16:10:03Z

I think it's better that we only backport a deprecation and warning suppression to CCCL 2.8, leaving Thrust untouched, and then properly rework Thrust iterators for CCCL 3.0. I will change this PR.

bernhardmgruber · 2025-01-22T16:11:45Z

I pushed the state of this PR into #3480, where we can continue the replacement and replace this PR by a pure deprecation now.

We keep CUB iterators inside the CUB implementation headers, because some of those are exposed to NVRTC which cannot compile Thrust iterators yet.
