We are studying the possible developpment of GPGPU solution for image processing. Once the process is done, we need to send an array of bytes to electronic board with a RAW Ethernet format.
Currently, we don’t have GPGPU solution, so we can pass throught CPU and use WinPCap dll to send our data throught Ethernet.
We have seen that GPUdirect RDMA technology allows to communicate between GPU and other PCIe devices (Ethernet), is that right ? If yes, do we have to know the full design of the Network card (memory maping) ?
We cannot afford to bring back data from GPU TO CPU because of their size.
We haven’t found many example and documentation on this subject yet and we want to be sure of the possibility to do what we need before starting the developpement.
