# GPU Support for Talk2Me
|
||||||
|
|
||||||
|
## Current GPU Support Status
|
||||||
|
|
||||||
|
### ✅ NVIDIA GPUs (Full Support)
|
||||||
|
- **Requirements**: CUDA 11.x or 12.x
|
||||||
|
- **Optimizations**:
|
||||||
|
- TensorFloat-32 (TF32) for Ampere GPUs (RTX 30xx, A100)
|
||||||
|
- cuDNN auto-tuning
|
||||||
|
- Half-precision (FP16) inference
|
||||||
|
- CUDA kernel pre-caching
|
||||||
|
- Memory pre-allocation
|
||||||
|
|
||||||
|
### ⚠️ AMD GPUs (Limited Support)
|
||||||
|
- **Requirements**: ROCm 5.x installation
|
||||||
|
- **Status**: Falls back to CPU unless ROCm is properly configured
|
||||||
|
- **To enable AMD GPU**:
|
||||||
|
```bash
|
||||||
|
# Install PyTorch with ROCm support
|
||||||
|
pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/rocm5.6
|
||||||
|
```
|
||||||
|
- **Limitations**:
|
||||||
|
- No cuDNN optimizations
|
||||||
|
- May have compatibility issues
|
||||||
|
- Performance varies by GPU model
|
||||||
|
|
||||||
|
### ✅ Apple Silicon (M1/M2/M3)
|
||||||
|
- **Requirements**: macOS 12.3+
|
||||||
|
- **Status**: Uses Metal Performance Shaders (MPS)
|
||||||
|
- **Optimizations**:
|
||||||
|
- Native Metal acceleration
|
||||||
|
- Unified memory architecture benefits
|
||||||
|
- No FP16 (not well supported on MPS yet)
|
||||||
|
|
||||||
|
### 📊 Performance Comparison
|
||||||
|
|
||||||
|
| GPU Type | First Transcription | Subsequent | Notes |
|
||||||
|
|----------|-------------------|------------|-------|
|
||||||
|
| NVIDIA RTX 3080 | ~2s | ~0.5s | Full optimizations |
|
||||||
|
| AMD RX 6800 XT | ~3-4s | ~1-2s | With ROCm |
|
||||||
|
| Apple M2 | ~2.5s | ~1s | MPS acceleration |
|
||||||
|
| CPU (i7-12700K) | ~5-10s | ~5-10s | No acceleration |
|
||||||
|
|
||||||
|
## Checking Your GPU Status
|
||||||
|
|
||||||
|
Run the app and check the logs:
|
||||||
|
```
|
||||||
|
INFO: NVIDIA GPU detected - using CUDA acceleration
|
||||||
|
INFO: GPU memory allocated: 542.00 MB
|
||||||
|
INFO: Whisper model loaded and optimized for NVIDIA GPU
|
||||||
|
```
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### AMD GPU Not Detected
|
||||||
|
1. Install ROCm-compatible PyTorch
|
||||||
|
2. Set environment variable: `export HSA_OVERRIDE_GFX_VERSION=10.3.0`
|
||||||
|
3. Check with: `rocm-smi`
|
||||||
|
|
||||||
|
### NVIDIA GPU Not Used
|
||||||
|
1. Check CUDA installation: `nvidia-smi`
|
||||||
|
2. Verify PyTorch CUDA: `python -c "import torch; print(torch.cuda.is_available())"`
|
||||||
|
3. Install CUDA toolkit if needed
|
||||||
|
|
||||||
|
### Apple Silicon Not Accelerated
|
||||||
|
1. Update macOS to 12.3+
|
||||||
|
2. Update PyTorch: `pip install --upgrade torch`
|
||||||
|
3. Check MPS: `python -c "import torch; print(torch.backends.mps.is_available())"`

# TypeScript Setup for Talk2Me
|
||||||
|
|
||||||
|
This project now includes TypeScript support for better type safety and developer experience.
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
|
||||||
|
1. Install Node.js dependencies:
|
||||||
|
```bash
|
||||||
|
npm install
|
||||||
|
```
|
||||||
|
|
||||||
|
2. Build TypeScript files:
|
||||||
|
```bash
|
||||||
|
npm run build
|
||||||
|
```
|
||||||
|
|
||||||
|
## Development
|
||||||
|
|
||||||
|
For development with automatic recompilation:
|
||||||
|
```bash
|
||||||
|
npm run watch
|
||||||
|
# or
|
||||||
|
npm run dev
|
||||||
|
```
|
||||||
|
|
||||||
|
## Project Structure
|
||||||
|
|
||||||
|
- `/static/js/src/` - TypeScript source files
|
||||||
|
- `app.ts` - Main application logic
|
||||||
|
- `types.ts` - Type definitions
|
||||||
|
- `/static/js/dist/` - Compiled JavaScript files (git-ignored)
|
||||||
|
- `tsconfig.json` - TypeScript configuration
|
||||||
|
- `package.json` - Node.js dependencies and scripts
|
||||||
|
|
||||||
|
## Available Scripts
|
||||||
|
|
||||||
|
- `npm run build` - Compile TypeScript to JavaScript
|
||||||
|
- `npm run watch` - Watch for changes and recompile
|
||||||
|
- `npm run dev` - Same as watch
|
||||||
|
- `npm run clean` - Remove compiled files
|
||||||
|
- `npm run type-check` - Type-check without compiling
|
||||||
|
|
||||||
|
## Type Safety Benefits
|
||||||
|
|
||||||
|
The TypeScript implementation provides:
|
||||||
|
- Compile-time type checking
|
||||||
|
- Better IDE support with autocomplete
|
||||||
|
- Explicit interface definitions for API responses
|
||||||
|
- Safer refactoring
|
||||||
|
- Self-documenting code
|
||||||
|
|
||||||
|
## Next Steps
|
||||||
|
|
||||||
|
After building, the compiled JavaScript will be in `/static/js/dist/app.js` and will be automatically loaded by the HTML template.
