CPU Benchmark Tool

A multi-threaded CPU benchmark that measures floating-point and integer performance.

Build

g++ -std=c++11 -O2 -pthread cpu_benchmark.cpp -o cpu_benchmark

Usage

./cpu_benchmark [duration_seconds]

• duration_seconds - Optional. Time per test in seconds (default: 5)

Example

./cpu_benchmark 10

Output

The benchmark runs four tests:

• Floating-point operations (all cores)
• Integer operations (all cores)
• Floating-point operations (single thread)
• Integer operations (single thread)

Results show MOPS (Million Operations per Second) for each test.
