Replace pointer-based RMM APIs (which will soon be deprecated) with ref-based alternatives as part of the RMM CCCL 3.2 memory resource migration: - device_resources_manager.hpp: set_current_device_resource() → set_current_device_resource_ref() - benchmark.hpp: Update using_pool_memory_res to use ref-based APIs - gather.cu: Update to use ref-based APIs for memory resource management - subsample.cu: Update to use ref-based APIs for memory resource management - buffer.cpp: set_current_device_resource() → set_current_device_resource_ref()
Change mem_resource_ from device_async_resource_ref to cuda::mr::any_resource to ensure the memory resource lifetime is properly managed. This is part of the RMM CCCL 3.2 migration.

This seems like a change with potential for unexpected side-effects. I'd urge to merge this asap if it cannot be delayed to 26.04. |

The changes look good to me, there is one CI failure that looks fairly minor: [ RUN ] DeviceResourcesManager.ObeysSetters

Expected: (mr) != (nullptr), actual: NULL vs (nullptr)but I agree with @csadorf that I'd rather be conservative and aim this to |

This should target 26.04, I’ll update you after I’ve had time to figure out the errors in this and other repositories. |
