DOCA GPUNetIO 如何统一 NVIDIA 软件栈中的 GPU 发起网络通信
How DOCA GPUNetIO Unifies GPU-Initiated Networking Across the NVIDIA Software Stack
NVIDIA DOCA GPUNetIO 让网络与数据移动成为 GPU 直接控制的一等操作，而非由主机 CPU 驱动的服务。当 CPU 介入每一次网络事务时就会成为关键路径上的瓶颈，增加延迟并限制分布式应用的实时响应效率。该方案旨在跨 NVIDIA 软件栈统一 GPU 发起的网络通信。
GPU applications increasingly need networking and data movement to behave like first-class GPU-controlled operations rather than host-driven services. When the...
GPU applications increasingly need networking and data movement to behave like first-class GPU-controlled operations rather than host-driven services. When the CPU sits in the middle of every network transaction, it becomes a bottleneck on the critical path, adding latency and limiting how efficiently distributed applications can respond in real time. NVIDIA DOCA GPUNetIO…
