## [Introduction] Muduo Lock-Free Work Stealing Engine: Hardware-Aware Concurrent Scheduling Solution Optimized for LLM Inference

This project is a hardware-aware concurrent task engine designed specifically for the Muduo network library. It optimizes performance for asymmetric workloads such as LLM inference using techniques like lock-free work stealing and cache line alignment, addressing the performance bottlenecks of traditional thread pools under heterogeneous requests.

## Technical Background: Fundamentals of Muduo and Concurrent Scheduling

### Muduo Network Library
Muduo is a C++ network library based on the Reactor pattern, using a one-loop-per-thread model where each thread maintains its own event loop.
### Work Stealing Scheduling
Work stealing is a dynamic load balancing technique where each thread maintains its own task queue, and idle threads steal tasks from other queues to reduce synchronization overhead.
### Challenges in Lock-Free Programming
Implementing lock-free data structures requires solving issues like memory ordering, ABA problem, and cache consistency.

## Key Design Highlights: Lock-Free Queue and Hardware-Aware Optimization

### 1. Lock-Free Work Stealing Queue
Thread-local operations require no synchronization; stealing operations are atomically safe; cache line alignment reduces false sharing.
### Hardware-Aware Optimization
- Cache line padding: Ensure queue head/tail pointers, metadata, and task data are separated; key counters are aligned by cache lines.
- NUMA awareness: Prioritize memory allocation from local nodes; stealing strategies consider topology to reduce cross-node access.
