When you try to call the `Reduce` operation in the CUDA device adapter with a sufficently complex interator type, you get a compile error that says `error: cannot pass an argument with a user-provided copy-constructor to a device-side kernel launch`. This appears to be a bug in either nvcc or Thrust. I believe it is related to the following reported issues: * https://github.com/thrust/thrust/issues/928 * https://github.com/thrust/thrust/issues/1044 Work around this problem by making a special condition for calling `Reduce` with an `ArrayHandleMultiplexer` that calls the generic algorithm in `DeviceAdapterAlgorithmGeneral` instead of the algorithm in Thrust. |
