UnverifiedGPU Direct Storage（GDS）通过建立NVMe SSD与GPU显存之间的直接DMA通道，绕过CPU内存，在实际测试中可将大文件加载带宽提升2-5倍77% similarUnverifiedGPUDirect Storage (GDS) is a technology introduced by NVIDIA around 2020 that allows storage devices to write data directly into GPU memory via the PCIe bus, bypassing CPU and system memory intermediaries.77% similarVerifiedThe GPU memory hierarchy from fastest to slowest is: registers, L1 cache/shared memory, L2 cache, global memory (VRAM).69% similarUnverifiedThe PS5's 16GB GDDR6 unified memory architecture lets the CPU and GPU share the same memory pool, so model weights do not need to be copied back and forth between devices and in theory only need to be loaded once.68% similarUnverifiedGDS establishes a direct storage-to-GPU channel via direct memory access (DMA), making the data path shorter and more predictable.68% similar
