UnverifiedBefore introducing GDS, one should first use a profiler to confirm that the bottleneck is on the data-loading side, then assess whether the storage devices and file system meet the prerequisites.73% 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.73% similarUnverifiedComputeFence also checks GPU visibility, Accelerate configuration, persistence of the checkpoint directory, and remaining disk space.73% similarUnverifiedWhen using GDS, the target buffer must reside in GPU memory and meet alignment requirements (typically 4KB or larger), otherwise it falls back to a compatibility path.71% similarUnverifiedGPU 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70% similar
