----------------------------------------------------------------------------
```

## Usage

### Prerequisites
- NVIDIA Driver
- CUDA Toolkit (I use 13.1)
- CMake (>= 3.18)
- A C++17 compliant compiler

### Build
```bash
# Clone the repository
git clone https://github.com/stlin256/CUDABurner.git
cd CUDABurner

mkdir build
cd build
cmake ..
make -j
```

### Run
The executable `CUDABurner` will be located in the `build` directory.

```bash
# Run with interactive menu
./CUDABurner

# Run Benchmark Test (all precisions)
./CUDABurner --mode benchmark

# Run Benchmark Test (specific precisions)
./CUDABurner --mode benchmark --precision FP32 FP16 TF32

# Run Stress Test
./CUDABurner --mode stress
```

## Known Issues
- **FP8/FP4 Not Implemented**: Benchmark tests for FP8 and FP4 precision are not yet implemented.
- **Insufficient Stress**: The current stress-test (`power_virus_kernel`) might not be sufficient to push GPUs to their absolute power limit.

## 使用方法

### 环境要求
- NVIDIA 驱动
- CUDA Toolkit (作者使用13.1)
- CMake (>= 3.18)
- 支持 C++17 的编译器

### 编译
```bash
# 克隆仓库
git clone https://github.com/stlin256/CUDABurner.git
cd CUDABurner

mkdir build
cd build
cmake ..
make -j
```

### 运行
可执行文件 `CUDABurner` 将会生成在 `build` 目录下。

```bash
# 以交互式菜单运行
./CUDABurner

# 运行算力基准测试 (所有精度)
./CUDABurner --mode benchmark

# 运行算力基准测试 (指定精度)
./CUDABurner --mode benchmark --precision FP32 FP16 TF32

# 运行压力测试 (烤机)
./CUDABurner --mode stress
```

## 已知问题
- **FP8/FP4 未实现**: 针对 FP8 和 FP4 精度的算力基准测试尚未实现。
- **烤机压力不足**: 当前的压力测试程序不足以让现代的高功耗 GPU 达到其极限功耗。
