Introducing Low-Level GPU Virtual Memory Management

Hello, @Cory.Perry
i have an problem when i used GPUDirect RDMA. The detail as follow:

  1. I used cuMemCreate/cuMemMap/cuMemMap to get a device memory
  2. And then i used the ibv_reg_mr_iova2 to register the device memory allocated in step 1, then the error “bad address” occurs.
    So i want to know whether the device memory allocated by low level virtual memory management api support the GPUDirect RDMA or not? If support, how to register the memory to support GPUDirect RDMA.
    Thanks!
