UnverifiedIn the GDS scenario, storage devices can write directly into GPU memory (BAR space) via point-to-point (P2P) transactions on the PCIe bus, bypassing system memory.67% similarUnverifiedThe page cache is the memory region the operating system kernel uses to cache file data; the GDS direct path typically bypasses the page cache (by opening files with O_DIRECT).66% similarUnverified现代SaaS缓存体系通常分为CDN边缘缓存、反向代理缓存和内存缓存，每一层都需独立设计租户隔离策略64% similarUnverifiedBefore 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.63% similarUnverifiedGDS establishes a direct storage-to-GPU channel via direct memory access (DMA), making the data path shorter and more predictable.63% similar
