GMI-DRL introduces a sub-GPU abstraction called GPU Multiplexing Instance (GMI) plus an adaptive Coordinator and a specialized Communicator to map heterogeneous DRL tasks to multi-GPU hardware, adapt instance granularity, and reduce inter-instance traffic. Implementation uses DGX-A100 with PyTorch, NVIDIA gym and NCCL-style communication; experiments show up to 2.34x training throughput and up to 40.8% higher GPU utilization compared to state-of-the-art baselines, and reports better packing and hierarchical gradient reduction strategies.
