⚙️ Benchmarker

A simple CPU benchmarker written in C++, focused on running basic arithmetic tests to evaluate CPU performance.

---

🧠 About

Benchmarker runs a suite of low-level math workloads — including addition, multiplication, division, and more — to assess how a system’s CPU handles fundamental operations.
Ideal for quick, local performance insights.

🚀 Quick Start

Prerequisites

• A C++ compiler (e.g., g++, clang++, or MSVC)
• Make (optional, for using the provided Makefile)

Build

From the root directory:

make

Run

Execute the benchmark:

./benchmarker [options]

By default, it runs all tests, measures execution time, and prints results.

🧩 Features

• ✅ Multiple arithmetic workloads: includes addition, multiplication, division, and more
• 🔁 Configurable loop count: control the number of iterations per benchmark
• 🧪 Command-line interface: run specific tests with customizable options
• 📊 Time-based measurement: outputs elapsed time and average operation duration
• 🧼 Clean and minimal C++ codebase: easy to understand, extend, and maintain
• 🧩 Modular test design: add your own benchmarks with minimal effort
• 🖥️ Single-threaded CPU stress: tests core computation performance without parallelism

📚 How It Works

1. Test Suite: Benchmarker includes a set of arithmetic test functions (e.g., add, multiply, divide).
2. Loop Execution: Each test is executed repeatedly for a defined number of iterations (e.g., 100 million times).
3. Timing: Uses high-resolution timers (std::chrono) to measure the total time taken by each test.
4. Result Reporting: Prints out:
   • Total time taken for the operation
   • Average time per operation (nanoseconds/op)
5. CLI Integration: Command-line arguments allow users to choose specific tests and set loop counts.
6. Performance Baseline: Helps compare CPU behavior across devices or compiler optimization levels.
