## 🎯 Architecture Overview
|
|
|
|
### Layer 1: Abstract Interface (`compute_provider.py`)
|
|
- **ComputeProvider**: Abstract base class for all backends
|
|
- **ComputeBackend**: Enumeration of available backends
|
|
- **ComputeDevice**: Device information and management
|
|
- **ComputeProviderFactory**: Factory pattern for backend creation
|
|
|
|
### Layer 2: Backend Implementations
|
|
- **CUDA Provider**: NVIDIA GPU acceleration with PyCUDA
|
|
- **CPU Provider**: NumPy-based fallback implementation
|
|
- **Apple Silicon Provider**: Metal-based Apple Silicon acceleration
|
|
|
|
### Layer 3: High-Level Manager (`gpu_manager.py`)
|
|
- **GPUAccelerationManager**: Main user-facing class
|
|
- **Auto-detection**: Automatic backend selection
|
|
- **Fallback handling**: Graceful degradation to CPU
|
|
- **Performance monitoring**: Comprehensive metrics
|
|
|
|
### Layer 4: API Layer (`api_service.py`)
|
|
- **FastAPI Integration**: REST API for ZK operations
|
|
- **Backend-agnostic**: No backend-specific code
|
|
- **Error handling**: Proper error responses
|
|
- **Performance endpoints**: Built-in performance monitoring
|
|
|
|
## 🔄 Migration Path

|
|
## 🚀 Usage Patterns
|
|
|
|
### Basic Usage
|
|
```python
|
|
from gpu_acceleration import GPUAccelerationManager
|
|
|
|
# Auto-detect and initialize
|
|
gpu = GPUAccelerationManager()
|
|
gpu.initialize()
|
|
result = gpu.field_add(a, b)
|
|
```
|
|
|
|
### Context Manager
|
|
```python
|
|
from gpu_acceleration import GPUAccelerationContext
|
|
|
|
with GPUAccelerationContext() as gpu:
|
|
result = gpu.field_mul(a, b)
|
|
# Automatically shutdown
|
|
```
|
|
|
|
### Backend Selection
|
|
```python
|
|
from gpu_acceleration import create_gpu_manager
|
|
|
|
# Specify backend
|
|
gpu = create_gpu_manager(backend="cuda")
|
|
result = gpu.field_add(a, b)
|
|
```
|
|
|
|
### Quick Functions
|
|
```python
|
|
from gpu_acceleration import quick_field_add
|
|
|
|
result = quick_field_add(a, b)
|
|
```
|
|
|
|
## 📊 Benefits

|
|
- **Easy Extension**: Simple to add new backends
|
|
- **Clear Documentation**: Comprehensive documentation and examples
|
|
|
|
## 🔧 Configuration
|
|
|
|
### Environment Variables
|
|
