# Test del sistema completo
python3 analisys_04.py --max-records 1000000 --demo
```

## 🔧 Troubleshooting AlmaLinux

### Problema: CuDF non installa
```bash
# Fallback: compila da sorgente
git clone --recurse-submodules https://github.com/rapidsai/cudf.git
cd cudf
./build.sh
```

### Problema: CUDA version mismatch
```bash
# Verifica versioni
nvcc --version
cat /usr/local/cuda/version.txt
python3 -c "import cupy; print(cupy.cuda.runtime.runtimeGetVersion())"
```

### Problema: Out of Memory Tesla M60
```bash
# Riduci batch size
export CUDF_SPILL_STATS=1
export LIBCUDF_CUFILE_POLICY=OFF
```

**Note per AlmaLinux**: 
- Conda è più affidabile di pip per RAPIDS
- Tesla M60 CC 5.2 supportata da CUDA 12.x
- Memory management critico con 8GB

```

## 📊 UTILIZZO MEMORIA GPU

### Tesla M60 8GB - Limits Raccomandati:

| Records | CuDF Mode | TensorFlow Mode | CPU Fallback |
|---------|-----------|-----------------|--------------|
| 100K | ✅ Full GPU | ✅ Full GPU | ✅ OK |
| 500K | ✅ Full GPU | ✅ Full GPU | ⚠️ Slow |
| 1M | ✅ Full GPU | ⚠️ Hybrid | ❌ Too Slow |
| 2M+ | ⚠️ Batched | ❌ Limit | ❌ Impossible |

## 🔧 RISOLUZIONE PROBLEMI

### Errore: "CUDA out of memory"
```bash
# Riduci batch size
export CUDA_VISIBLE_DEVICES=0
python train_gpu_native_1M.py --max-records 500000
```

### Errore: "CuDF not found"
```bash
# Reinstalla CuDF
pip uninstall cudf-cu11
pip install cudf-cu11==23.12.*
```

### Errore: "TF_GPU_ALLOCATOR legacy"
✅ **Normale per Tesla M60 CC 5.2** - Il sistema è configurato automaticamente.

## 🎯 BEST PRACTICES

### 1. Monitora memoria GPU
```python
import cupy as cp
pool = cp.get_default_memory_pool()
print(f"GPU Memory: {pool.used_bytes() / 1024**3:.1f}GB")
```

### 2. Usa CuDF quando possibile
- **CuDF**: 1M+ record supportati nativamente
- **TensorFlow**: Limit 500K record su Tesla M60
- **CPU**: Limit 100K record (troppo lento)

### 3. Ottimizza parametri Tesla M60
```python
# analisys_04.py automatically configura:
max_records = 1000000 if CUDF_AVAILABLE else 500000
```
