DMA from Network Card to AMD Card Memory

Jump to solution

Here is a paper on doing this from a 10G network card to an Nvidia card:

Is this possible with AMD cards?  Firepro?

Support to exchange data with the FirePro GPU needs to be supported by the device driver of the network card as well. Currently I am not aware of a network device that has implemented DirectGMA.As mentioned in the above thread it is possible to use DirectGMA to do peer to peer transfers between a FirePro GPU and a network device but the network device needs to have DirectGMA support implemented.
