If all goes well you will see the following output:
Inputs: --device 0 --kernel ./reduction/reduce_sum.aocx
Using OpenCL device: EmulatorDevice : Emulated Device
extension aocx
kernel result 523776
Follow the instructions above and add -DKERNEL_CIRCUIT=ON to the cmake command.
cd build-oclsandbox
./reduction/reducer --device 0 --kernel ./reduction/reduce_sum.aocx
