    DirectGMA support?

    linux

      Does Mellanox support DirectGMA?

       

      DirectGMA is AMD's PCIe peer-to-peer mechanism which is similar to Nvidia's GPUDirect.

       

      The one reference I could find was in a Mellanox slide presentation by Todd Wilde entitled "Paving The Road to Exascale Computing":

       

      "AMD DirectGMA P2P: Peer-to-Peer GPU-to-HCA data path under development"

       

      Otherwise there is seemingly no mention of DirectGMA support.
