If without Infiniband, how can I use GPUDirect RDMA to transfer data from NIC to GPU device bypass CPU and host memory?

I want to receive data from a NIC and transfer the data to GPU Device directly.
But the question is, the host machine does not have a IB device.

Can I use GPUDirect RDMA to receive data and transfer them to GPU device.

Hi ,

NVIDIA® GPUDirect RDMA is an API between IB CORE and peer memory clients that requires NVIDIA InfiniBand card .

It’s not supported on OEM Ethernet NIC .

Thanks
