nproc

Overview

nproc is a command-line utility designed to retrieve and display the number of processing units available (and online) on the system. It provides an essential way for developers and system administrators to understand system resources for optimization and tuning purposes.

Features

• Retrieve the number of available processing units.
• Supports multiple platforms (Linux, macOS, etc.).
• Lightweight and efficient implementation.

Prerequisites

To build and run nproc, you'll need the following:

• C Compiler: A modern C compiler that supports C11 or later.
• CMake: Version 3.30 or higher.
• Standard C Library: Whatever you have installed should work, but don't take my word for it on Windows.

Building the Project

To build the project, follow these steps:

1. Clone the repository:

   git clone https://github.com/sindastra/nproc
   cd nproc

2. Create a build directory and navigate into it:

   mkdir build
   cd build

3. Run CMake to configure the build system:

   cmake ..

4. Compile the project:

   make

5. The executable will be generated in the build directory.

Usage

Run the nproc executable from the command line:

./nproc

It will display the number of available (and online) processing units detected on your system.

Example Output

Acknowledgments

This README was written mostly by an LLM, with the nonsense corrected and jokes added by a human. I think it took me more time to correct things than to write it from scratch. But then again, I don't think I would have made it this long and polished from scratch.
