A simple DPDK ping-pong benchmark with DPU forwarding

DPU Ping-Pong

The repo contains code for two programs:

dpdk_pingpong: A simple program to evaluate raw DPDK latency with DPU forwarding. The client sends a certain number of packets to the server as a ping, then the server returns them to the client as a pong. The client records such ping-pong round trip time. The number of packets to send is based on the user-specified message size range.

dpu_fwd: A simple program to forward network packet from port x to port x^1. Currently, every port will be automatically assigned to a core.

Note the programs have been evaluated on 2 Ubuntu 18.04 machines with DPDK 20.11.2 and BlueField-2 DPUs with DPDK 20.11.2.

Prepare

For the DPDK installation and setup, please refer to the DPDK documentation (https://core.dpdk.org/doc/quick-start/).

Build

We can use either cmake or make to build the program.

We are using pkg-config to locate DPDK.

export PKG_CONFIG_PATH=/path/to/DPDK/pkgconfig

To use make

cd /path/to/dpu-pingpong
make dpdk_pingpong
make dpu_fwd

To use cmake

cd /path/to/dpu-pingpong
mkdir build
cd build
cmake ..
make dpdk_pingpong
make dpu_fwd

Run

On the server host

sudo ./dpdk_pingpong -- -s

On the client host

sudo ./dpdk_pingpong -- -c [server MAC]

On both the server and the client DPUs

sudo ./dpu_fwd -l 0-1
