# RinHash ROCm GPU Direct Integration

This build uses the existing `cpuminer-rocm-build` container to avoid dependency issues.

## Files Created

### GPU Libraries (`gpu-libs/`)
- `librinhash_hip.so` - Shared library for GPU acceleration
- `*.cuh` - Header files for GPU functions

## Usage

### 1. Copy GPU library to system
```bash
sudo cp gpu-libs/librinhash_hip.so /usr/local/lib/
sudo ldconfig
```

### 2. For cpuminer integration
Modify your cpuminer RinHash implementation to use GPU functions:

```c
#include <dlfcn.h>

// Load GPU library
void* gpu_lib = dlopen("librinhash_hip.so", RTLD_LAZY);
if (gpu_lib) {
    // Use GPU functions
    rinhash_cuda_function = dlsym(gpu_lib, "rinhash_cuda");
}
```

### 3. Build cpuminer with GPU support
```bash
./configure CFLAGS="-O3 -march=native"
make -j$(nproc)
```

## Testing

Test GPU support:
```bash
rocm-smi  # Check GPU availability
```

Test library loading:
```bash
ldd librinhash_hip.so
```
