Yes, but using the DMA engine in the NVMe drive to write directly into GPU RAM, rather than go through system RAM first. This was not previously possible, as DMA is almost always to/from main RAM. From the article [emphasis added]: > If a DMA engine in an NVMe drive or elsewhere near storage can be used to move data instead of the GPU’s DMA engine, then there’s no interference in the path between the CPU and GPU. Our use of DMA engines on local NVMe drives vs. the GPU’s DMA engines increased I/O bandwidth to 13.3 GB/s, which yielded around a 10% performance improvement relative to the CPU to GPU memory transfer rate of 12.0 GB/s shown in Table 1 below. They don't seem to have revealed many more technical details about how they did it, just a lot of benchmarks. I presume this only works where there is a shared PCI-E switch in between the GPU and NVMe drive, and so traffic can be routed past the CPU?
