Data Center Infrastructure

What is a primary advantage of using NVIDIA GPUDirect RDMA in an AI environment?

  • A It increases the power efficiency and thermal management of GPUs.
  • B It reduces the latency and bandwidth overhead of remote memory access between GPUs.
  • C It enables faster data transfers between GPUs and CPUs without involving the operating system.
  • D It allows multiple GPUs to share the same memory space without any synchronization.
Explanation

NVIDIA GPUDirect RDMA enables direct data exchange between GPU memory and third-party PCIe peer devices, such as network interfaces, bypassing CPU host-memory staging. This reduces communication overhead and improves the latency and effective bandwidth of remote GPU memory access.
