PCIe peer-to-peer communication (P2P) is a PCIe feature which enables two PCIe devices to directly transfer data between each other without using host RAM as a temporary storage. The latest version of Alveo PCIe platforms support P2P feature via PCIe Resizeable BAR Capability. Data can be dire...
The system includes a first processor configured to initiate a communication arrangement between a first peripheral component interconnect express (PCIe) device and a second PCIe device. The communication arrangement is configured to detect transfers from the first PCIe device to one or more addresses ...

Graphics applications typically use x16-width links. Peer-to-peer communication is supported in switch hardware, allowing the shortest possible path between the peers. As with the fanout switch, the links can be at any supported PCle speed, for any supported width. 如上图: GPU1 can communicate...

Hi, we are trying to achieve communication between two endpoint FPGAs. The architecture of the system is as follows: PC (root complex) | pcie switch
PEER-TO-PEER COMMUNICATION FOR GRAPHICS PROCESSING UNITS function in the PCIe fabric configured to isolate a device PCIe address domain associated with the GPUs from at least a local PCIe address domain associated with a host processor that initiates the peer-to-peer arrangement between the ... ...
We are trying to make a peer-to- peer transaction between 2 End-Points, through Intel chipset without succession. (Not through CPU/ CPU memory). The 2 E.P. connected to PCIe channels of the QM57 \ QM77 \ QM170. There is communication between the EP and the CPU/CPU memory. but not...
I am a new user of UCX. Now have a situation where two different containers each use different GPU, and the two GPUs devices on the Host can communicate via PCIe P2P or NVLink. But in containers they can't communicate via PCIe P2P or NVL...
• A Root complex that supports peer-to-peer transactions is allowed to split packets. • Addition of Root Complex Integrated Endpoint and Event Collector definition as well as related extended capability registers. • Additional Byte Enable usage rule. ...
