NCCL is strictly a collective communication library. It provides optimized routines for operations such as broadcast or all-reduce among multiple GPUs, but not any mechanisms for task distribution or control. If you are just starting out with multi-GPU programming, CUDA-aware MPI might be a good place to start. Here is a presentation from last year's GTC that may be helpful.
