ThreadPool

A lightweight, efficient C++ thread pool implementation providing a simple API for task submission and safe shutdown. Designed for clarity, performance, and ease of integration into existing C++ projects.

Features

• Fixed-size thread pool with a task queue
• Safe shutdown and graceful join
• Minimal, header-first API (ThreadPool.hpp) and a small implementation file
• Simple CMake-based build and test setup

Requirements

• C++17 (or newer) compatible compiler (GCC, Clang)
• CMake 4.3.2+

Building

Clone the repository and build with CMake:

git clone <repo-url>
cd ThreadPool
mkdir -p build && cd build
cmake ..

This produces the example/test executable threadpool_test in the build/ directory.

Example

A minimal example is provided in src/main.cpp and a test runner is available at build/threadpool_test when built with CMake.

API (overview)

• ThreadPool(size_t numThreads) — create pool with numThreads workers.
• enqueue(Fn&& f, Args&&... args) — submit a task and receive a std::future.
• shutdown() — stops accepting tasks and joins worker threads.

See src/ThreadPool.hpp for method signatures and usage details.
