I am studying the source code of TVM, and I am confused about the constant kMaxNumGPUs (=32) in /src/runtime/cuda/cuda_module.h. To my mind, when we run the compiled model, we can only choose 1 GPU card. If this is true, why TVM runtime set the kMaxNumGPUs to 32 and keeps the memory allocation status of kMaxNumGPUs GPU cards ?
