@griwes That doesn't clarify. Is `nv::target::device` is the bit-field of targets specified at the command line? Where is the active target manifested? It has to be somewhere.

I'm just trying to compile CUB/Thrust with this new dispatch mechanic. What are the implicit declarations needed to do that?

The problem is your macro in amd_hip_runtime.h is wrong ```cpp #define launch_bounds_impl1(requiredMaxThreadsPerBlock, minBlocksPerMultiprocessor) \ __attribute__((amdgpu_flat_work_group_size(1, requiredMaxThreadsPerBlock), \ amdgpu_waves_per_eu(minBlocksPerMultiprocessor))) ```
