"""
GPU-Ready Test Runner for AGMOHD Optimizer

This script provides a comprehensive testing framework for AGMOHD optimizer
that automatically detects and utilizes GPU/RTX hardware when available.

Usage:
    # On systems with RTX GPUs
    python test_gpu_ready.py

    # On systems with standard GPUs
    python test_gpu_ready.py

    # On CPU-only systems
    python test_gpu_ready.py

The script will automatically:
- Detect available hardware (CPU/GPU/RTX)
- Configure appropriate optimizations
- Run comprehensive performance tests
- Provide detailed optimization percentage reports
