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

🔧 Troubleshooting AlmaLinux

Problema: CuDF non installa

# Fallback: compila da sorgente
git clone --recurse-submodules https://github.com/rapidsai/cudf.git
cd cudf
./build.sh

Problema: CUDA version mismatch

# 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

# 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"

# Riduci batch size
export CUDA_VISIBLE_DEVICES=0
python train_gpu_native_1M.py --max-records 500000

Errore: "CuDF not found"

# 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

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

# analisys_04.py automatically configura:
max_records = 1000000 if CUDF_AVAILABLE else 500000
