Use libcu++ limits/trait in tests/benchmarks #3822

bernhardmgruber · 2025-02-15T12:38:37Z

This pulls out the non-breaking part of #3384, which:

Adds specialization of libcu++ traits for several types used for testing
Replace each use of CUB traits or std traits in unit tests or benchmarkes by cuda::std traits. Applies to limits as well.

This PR does NOT replace any use of CUB traits in the CUB/Thrust headers, because that would break any user opting in with a custom type by specializing CUB traits.

c2h/include/c2h/custom_type.h

 template <template <typename> class... Policies>
-class numeric_limits<c2h::custom_type_t<Policies...>>
+class __numeric_limits_impl<c2h::custom_type_t<Policies...>, __numeric_limits_type::__other>


Shouldnt this also work if we just specialized numeric_limits

It doesn't and I need your guidance here. The problem is that CUB sometimes queries numeric_limits<const T> and that does not find a specialization if I only specialize:

class numeric_limits<c2h::custom_type_t<Policies...>> { ... };

Specializing __numeric_limits_impl works, because numeric_limits strips CV qualifiers and passes the type to __numeric_limits_impl. What's the best practice? Should be specialize numeric_limits multiple times for T, const T, and maybe also for referneces of those? Or should we try harder inside CUB to call like numeric_limits<decay_t<T>>?

That is a bug in our implementation then: https://eel.is/c++draft/numeric.limits#general-5

The value of each member of a specialization of numeric_limits on a cv-qualified type cv T shall be equal to the value of the corresponding member of the specialization on the unqualified type T.

cub/cub/device/device_reduce.cuh

-      // replace with
-      // std::numeric_limits<T>::max() when
-      // C++11 support is more prevalent
+      // TODO(bgruber): replace with ::cuda::std::numeric_limits<T>::max() (breaking change)


I thought we were breaking things?

I wanted to separate non-breaking from breaking changes, so we can more easily roll if needed, and have a smaller diff to inspect with more attention.

miscco

I went through it, no change requested.

That said I found a few places where we are unconsistent about fully qualifying cuda::std

I specialized cuda::std::numeric_traits directly, and now I have failures in e.g. cub.cpp20.test.block_scan.alg_1.mode_0. Somehow the specialization is not picked up.

I specialized cuda::std::numeric_traits directly, and now I have failures in e.g. cub.cpp20.test.block_scan.alg_1.mode_0. Somehow the specialization is not picked up.

ok, this is a fun one. The test is broken on main, because c2h uses std::numeric_limits to generate test data but defines limits for vector types (e.g. uchar3) using cub::Traits. So the generated test data is just zeros and the test passes. This PR fixes this problem by accident and uncovers the broken test.

I reported the bug here: #3835. And will disable the test now in this PR.

cub/test/catch2_test_block_scan.cu

+// FIXME(bgruber): uchar3 fails the test, see #3835
+using vec_types        = c2h::type_list<ulonglong4, /*uchar3,*/ short2>;


I am disabling the failing test here. We should update #3835 once this PR is merged.
