Correct me if I'm wrong, but Microsoft's DirectStorage seems to me something like what the author is writing about. It lets you do eg massively parallel NVME file io ops from the GPU itself of lots of small files. This avoids the delay of the path through the CPU, any extra threads/saturation of the CPU, and even lets you do eg decompression of game assets on the GPU itself thereby saving even more CPU. This demo benchmark shows DEFLATE going from 1 GB/s on CPU to 7 GBs/ on GPU https://github.com/microsoft/DirectStorage/tree/main/Samples...
In Asynchronous IO: the next billion-dollar mistake?
