About this project

The EXTREME library offers cutting-edge speed and precision for low-latency applications. Designed for high-performance environments, it supports DPDK bindings, exponential pause techniques, and includes an example UDP receiver. Optimize resource usage while enhancing throughput with this powerful Rust library.

EXTREME Library

The EXTREME library is specially designed to provide remarkable speed and accuracy for low-latency and ultra-fast applications. It includes a collection of features optimized for performance, ensuring efficient operations in demanding environments.

Key Features

dpdk-: This is a binding library for Rust that integrates with the Data Plane Development Kit (DPDK), which is essential for achieving high packet processing speeds. Ensure the installation of the dpdk-dev package to utilize this functionality.
exp-pause: Leverage CPU PAUSE with an exponential counter to enhance performance during idle cycles.
udp-receiver: An example UDP receiver application demonstrating the capabilities of DPDK, which can be used as a starting point for developing low-latency networking solutions.

Running the Demo Application udp-receiver

To demonstrate the functionality of the udp-receiver, follow these steps:

Start the udp-receiver application with the command (note that sudo is required):
```
sudo cargo run -p udp-receiver
```

Configure an internal IP to enable packet transmission:

sudo ip addr add 192.168.100.1/24 dev dpdk-tap0
sudo ip link set dpdk-tap0 up

Initiate UDP packet transmission using netcat:

echo "DPDK передает привет языку Rust!" | nc -u -w1 192.168.100.99 9999

Check the console output of the udp-receiver application to confirm that the packet has been received successfully.

ExpPause::SpinCounter Performance Check

Testing the idle loop cycle on a single CPU core with turbostat reveals notable improvements when using the SpinCounter with exponential counting. After approximately 5 minutes of operation:

Using the SpinCounter results in a significant reduction in core power consumption, dropping from 3.15W to 0.38W, and a decrease in core temperature from 58℃ to 51℃. This illustrates the effectiveness of the EXTREME library in optimizing system performance while minimizing energy usage.
