cub/cub/device/device_reduce.cuh

cub/test/catch2_test_device_reduce_nondeterministic.cu

…ing for architecture at compile time to decide to fall back or not will not work because arch macros are 0 in host code

NaderAlAwar · 2025-08-05T16:19:58Z

the second option is to use emulation, https://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#atomic-functions, see __device__ double atomicAdd(double* address, double val)

@fbusato I ended up going with this approach. Falling back to another implementation in device_reduce.cuh with my previous approach did not work because the arch macros don't work in host code.

@NaderAlAwar be careful about NaNs if you want to go with this path😄

I ended up going with this approach. Falling back to another implementation in device_reduce.cuh with my previous approach did not work because the arch macros don't work in host code.

@NaderAlAwar be careful about NaNs if you want to go with this path😄

@fbusato after considering this and discussing with Georgii we decided to just disable atomic reduce with doubles for pre sm60. Supporting this might prove to be more trouble than it's worth.
