When OFF the ENABLE_CUDA_RTC option skips building the CUDA runtime compilation feature (CudaModule) that requires access to the CUDA driver API. The MXNet shared library build with this option OFF has no direct dependency on the CUDA driver library (e.g. libcuda.so) and can be used on both GPU and CPU hosts. CPU-only hosts require no stub CUDA driver library.

When ENABLE_CUDA_RTC is off and USE_CUDA is ON, can it still do everything on GPU like the normal build? What is lost? |

The only thing lost when USE_CUDA is ON and ENABLE_CUDA_RTC is OFF is calling the |
