Description

This rule checks the data transfer between the FPGAs through Peer to peer data transfer technique.

Explanation

PCIe® peer-to-peer communication (P2P) is a PCIe feature that enables two PCIe devices to directly transfer data between each other without using host RAM as temporary storage. The latest version of Alveo™ PCIe platforms support P2P feature via PCIe Resizeable BAR Capability.

Data can be directly transferred between the DDR/HBM of one Alveo PCIe device and DDR/HBM of a second Alveo PCIe device.
