C++11 simple threadpool example

• CMake > 3.16
• Boost > 1.65
• C++11 compatible compiler

1. Clone repository

git clone <url>

2. Enter project directory

cd threadpool-example

3. Run CMake

cmake -H. -Bbuild -DCMAKE_BUILD_TYPE=RELEASE

4. Build

cmake --build build

build folder now contains threadpool_demo executable - demo application for threadpool usage

Demo application computes matrix x vector multiplication in parallel with help of threadpool. Matrix and vector are generated randomly using uniform distribution.

Program options:

• threads_num,t - number of used threads
• verbose,v - print matrix, vector and result
• matrix_rows - number of rows in matrix
• matrix_cols - number of cols in matrix

1. Create threadpool with desired number of threads

threadpool_example::ThreadPool thp(threadsNum);

2. Push task to threadpool and get future result

auto future = thp.enqueue([](){
        std::cout << "I am a task";
        return 0;
    });

3. Optionaly wait for future result

std::cout << "result is " << future.get();
