Minimal HPX Demo

This project is a minimal demo to help new users get familiar with the HPX library. It demonstrates how to use HPX's core functionality, including asynchronous output (hpx::cout). The program prints "The answer is 42!" to the console using HPX's parallel execution engine.

What is HPX?

HPX is a C++ Standard Library for concurrency and parallelism, enabling distributed and asynchronous computing. HPX provides a unified API for local and distributed execution, making it ideal for applications that require high performance, scalability, and parallelism.

This project uses HPX's hpx_main to handle the underlying runtime initialization, allowing developers to focus directly on the code logic without worrying about manually managing the HPX runtime.

Project Structure

• simple_hpx.cpp: The main source file that prints "The answer is 42!" using HPX's asynchronous output capabilities (hpx::cout).
• CMakeLists.txt: The CMake configuration file that sets up the project, including the necessary HPX and Boost libraries.

Prerequisites

To compile and run this project, you'll need the following dependencies:

1. HPX: Install HPX via your package manager or build from source. Check out HPX installation guide.
2. Boost: Ensure Boost (version 1.71 or higher) is installed on your system. Boost installation guide.

Build Instructions

Follow these steps to build and run the project:

1. Clone the repository:

   git clone https://github.com/brakmic/simple_hpx.git
   cd simple_hpx

2. Create a build directory:

   mkdir build && cd build

3. Configure the project using CMake:

   cmake ..

4. Build the project:

   make

5. Run the program:

   ./simple_hpx

You should see the following output:

The answer is 42!
