That is not easily supported by the Nvidia driver itself: after having
run a CUDA kernel, one has to deinitialize CUDA and initialize OpenCL
before being able to run an OpenCL, and vice-versa, which means dropping
all memory etc. So we haven't implemented any particular support, and
you have to call starpu_shutdown() and starpu_init() again with a
different configuration, to choose between running the GPU in CUDA mode
or in OpenCL mode.
