Run C++ code easily on GPU lik Python language

Question

In order to run Python code with GPU (after installing all libraries for this), one can juste add these line before the code:

device_name= tf.test.gpu_device_name()
if device_name!='/device:GPU:0':
    raise SystemEror('GPU device not found')
else:
    print('GPU found!')

with tf.device("/device:GPU:0"):
    #python code here...

Is there any similar way to run existing C++ code on GPU ? I've searched and I found that one should install other libraries and re-write the C++ code. I would prefer something (if exists) in a similar way of Python.

Any ideas?

C++ doesn’t have any facilities built in for GPU programming, you’d need to use something like OpenCL (or CUDA if you have an Nvidia GPU) for compute, or OpenGL/Vulkan or another graphics library for graphics.
