Hi, I’m trying to pass an object with a wrapped CuArray to a kernel: import CUDA struct MyStruct arrayField::CUDA.CuArray{Float32, 1, Nothing} end function f!(obj::MyStruct) id = CUDA.threadIdx().x if id <= length(a) obj.arrayField[id] = id end nothing end myObj = MyS…

CuArray is the host-representation of a CUDA array, you need CuDeviceArray. That conversion happens automatically for known types, but you need to register your own Adapt.jl conversions for custom types.
