Hm, without a consumer equivalent to GPU Direct Storage (PCIe P2P DMA), this is not as cool as it could be. Still has to bounce to and from the CPU for no good

Hm, without a consumer equivalent to GPU Direct Storage (PCIe P2P DMA), this is not as cool as it could be. Still has to bounce to and from the CPU for no good reason.
- KeplerBoy 3y agoIsn't this the one DMA feature actually supported on consumer GPUs? I know it's not possible for NICs to directly write data into GPU Memory unless one uses Quadro or data center cards, but loading stuff from nvme drives into the GPU without involving host memory should be possible on all recent GPUs.
- nimish 3y agoNot that I'm aware of: https://developer.nvidia.com/gpudirect-storage https://developer.nvidia.com/gpudirect-storage is only supported on Linux. Microsoft DirectStorage isn't GPU Direct Storage, annoyingly enough. No idea what AMD's equivalent is though their FPGA's would be able to do anything.
