HPX HelloWorld Component

This project demonstrates how to create a basic HPX component that returns the number 42 when called. The project is structured as follows:

• Component: The core logic for returning a number is encapsulated inside an HPX component.
• Action: HPX actions are used to expose component functionality for asynchronous execution across distributed nodes.
• Main: The entry point where we create the component, call it, and print the result.

Getting Started

Prerequisites

• Install HPX following the HPX installation guide.
• Install Boost.
• Make sure you have CMake 3.19+ and a C++ compiler that supports C++23 (or change the CMake settings).

Building the Project

To build the project:

mkdir build
cd build
cmake ..
make

Running the Program

To run the fibonacci_demo_hpx program:

./hello_component_hpx

It will output the number 42 returned by the component.
