GPU Direct allows for direct data transfers from one GPU memory to another GPU memory, enabling direct remote access between GPU memories. This greatly enhances the efficiency of GPU cluster operations, offering significant improvements in both bandwidth and latency.

Accelerate data plane, networking, storage, and security, enabling in-network computing and in-network memory capabilities. Offloading CPU-intensive I/O operations enhances host efficiency.

By employing accelerated switching and packet processing technologies, network performance can be enhanced while reducing CPU overhead in the transmission of Internet Protocol (IP) packets, thereby freeing up more processor cycles to run applications.
