PLINK: A GPU-Initiated I/O Platform Exploiting NVMe Parallelism
PLINK (Parallel-Link), a GPU-initiated I/O platform that addresses this gap through three targeted optimizations: SQ/CQ decoupling to hide device latency, command-ID-indiscriminate polling to eliminate exhaustive CQ search overhead, and warp-level doorbell batching to minimize PCIe MMIO writes and reduce warp divergenc...
