Fix `cub::DeviceTransform` unwrapping `cudax:async_buffer::iterator` #4083

bernhardmgruber · 2025-03-11T11:56:03Z

This PR fixes a performance issue when cub::DeviceTransform is used with cudax:async_buffer, by fixing thrust::is_contiguous_iterator.

Adding tests requires CUB and Thrust unit tests to have access to cudax. Please advice me on how to correctly link against cudax.

ditto we should move to cudax

I kind of disagree. This test is more about cub::DeviceTransform correctly working on the async_device_vector, than whether the vector can be transformed.
