# Intel Arc GPU Optimization Guide

**Maximize LLM performance on Intel Arc Graphics + NPU**

This guide shows how to run **Llama 4** at "NVIDIA-like speeds" on Intel Arc integrated graphics using DuckDB + VSS for fast legislative analysis.

## 🎯 Why This Matters

If you're running on **Intel Core Ultra 7 165H** (or similar):
- ✅ You have **Intel Arc Graphics** (integrated GPU)
- ✅ You have an **NPU** (Neural Processing Unit) for AI workloads
- ✅ With **64GB RAM**, you can handle massive context windows

**Standard Ollama** defaults to CPU and runs slow. This guide fixes that.

## 🚀 Hardware Setup

### Your System (Example)
- **CPU**: Intel Core Ultra 7 165H
- **GPU**: Intel Arc Graphics (integrated)
- **NPU**: Intel AI Boost
- **RAM**: 64GB LPDDR5x
- **OS**: Windows 11 Enterprise / Linux

### Performance Breakdown

| Engine | Role | Performance Benefit |
|--------|------|---------------------|
| **Intel Arc GPU** | Vector Search & NER | 10-100x faster than CPU for embedding similarity |
| **64GB RAM** | Context Window | Analyze 100+ page bills without "forgetting" |
| **Intel NPU** | Background Tasks | Summarize daily updates while GPU handles heavy lifting |

## 📦 Installation

### Step 1: Install Intel-Optimized Environment

```bash
# Clone the repository
cd /path/to/open-navigator

# Run Intel setup script
chmod +x scripts/intel_llm_setup.sh
./scripts/intel_llm_setup.sh

# Activate environment
source .venv-intel/bin/activate
```

### Step 2: Install DuckDB + VSS Extension

```bash
# DuckDB is already installed by the setup script
# Test it:
python3 -c "import duckdb; print('DuckDB version:', duckdb.__version__)"

# Install VSS extension (in Python or CLI)
python3 << EOF
import duckdb
conn = duckdb.connect()
conn.execute("INSTALL vss")
conn.execute("LOAD vss")
print("✅ VSS extension loaded!")
EOF
```

### Step 3: Configure Intel Optimizations

Set these environment variables before running:

```bash
# Enable Intel GPU
export ZES_ENABLE_SYSMAN=1

# Use GPU for Ollama (if using Ollama)
export OLLAMA_NUM_GPU=999

# Enable IPEX-LLM optimizations
export IPEX_LLM_NUM_GPU=1
export ONEAPI_DEVICE_SELECTOR=level_zero:0
```

## 🔍 DuckDB + VSS Architecture

### Why DuckDB for Local AI?

**Traditional Approach (Postgres):**
```
LLM → Network → Postgres → Network → LLM
  ↑_____________500-1000ms_____________↑
```

**DuckDB Approach:**
```
LLM → DuckDB (embedded) → LLM
  ↑________20-50ms________↑
```

**10-50x faster context injection!**

### Vector Similarity Search (VSS)

DuckDB's VSS extension uses **HNSW** (Hierarchical Navigable Small World) index:

```python
import duckdb

conn = duckdb.connect("legislative.duckdb")
conn.execute("INSTALL vss")
conn.execute("LOAD vss")

# Create table with embeddings
conn.execute("""
    CREATE TABLE bills (
        bill_id VARCHAR,
        title TEXT,
        embedding FLOAT[384]  -- Sentence transformer
    )
""")

# Create HNSW index
conn.execute("""
    CREATE INDEX bills_vss_idx 
    ON bills USING HNSW (embedding)
""")

# Fast vector search (< 20ms for 10K bills)
query_embedding = [0.1, 0.2, ...]  # 384 dimensions
results = conn.execute("""
    SELECT bill_id, title, 
           array_distance(embedding, ?::FLOAT[384]) as distance
    FROM bills
    ORDER BY distance ASC
    LIMIT 10
""", [query_embedding]).fetchall()
```

## 🧠 LLM Inference with Intel Arc

### Option 1: OpenVINO (Recommended)

**Best for Intel Arc GPU**

```python
from optimum.intel import OVModelForCausalLM
from transformers import AutoTokenizer

# Load model optimized for Arc GPU
model = OVModelForCausalLM.from_pretrained(
    "meta-llama/Llama-3.2-3B-Instruct",
    export=True,
    device="GPU"  # Use Arc Graphics
)

tokenizer = AutoTokenizer.from_pretrained("meta-llama/Llama-3.2-3B-Instruct")

# Run inference
inputs = tokenizer("What are the key provisions of HB1234?", return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=512)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
```

### Option 2: IPEX-LLM

**Good for CPU + GPU hybrid**

```python
from intel_extension_for_pytorch import llm
import torch

# Load with IPEX optimizations
model = llm.optimize(model, dtype=torch.bfloat16)

# Inference uses Arc GPU automatically
with torch.inference_mode():
    outputs = model.generate(**inputs)
```

### Option 3: Ollama (Intel Build)

**Easiest for quick testing**

```bash
# Download Intel-optimized Ollama
wget https://ollama.com/download/ollama-linux-amd64

# Set GPU usage
export OLLAMA_NUM_GPU=999
export ZES_ENABLE_SYSMAN=1

# Run Ollama
ollama serve

# In another terminal:
ollama pull llama3.2
ollama run llama3.2 "Analyze this bill..."
```

## 🎯 Legislative Analysis Workflow

### Full Pipeline Example

```python
from scripts.legislative_analysis_intel import (
    DuckDBLegislativeAnalyzer,
    IntelOptimizedLLM,
    InterestGroup
)

# 1. Initialize DuckDB analyzer
with DuckDBLegislativeAnalyzer() as analyzer:
    # 2. Get bill context (< 50ms)
    bill = analyzer.get_bill_context("HB1234")
    testimony = analyzer.get_all_testimony_for_bill("HB1234")
    
    # 3. Initialize Intel-optimized LLM
    llm = IntelOptimizedLLM(model_name="meta-llama/Llama-3.2-3B-Instruct")
    llm.load_model(use_openvino=True)  # Arc GPU
    
    # 4. Extract structured data
    groups = llm.extract_interest_groups(bill, testimony)
    
    # 5. Results
    for group in groups:
        print(f"{group.group_name}: {group.stance} ({group.stance_score})")
        print(f"  Tradeoffs: {group.tradeoff_notes}")
```

### Output Schema

```json
{
  "groups": [
    {
      "group_name": "Alabama Dental Association",
      "lobbyist": "John Smith",
      "stance": "conditional",
      "stance_score": 0.6,
      "tradeoff_notes": "Support if Section 4 amended to include rural exemption",
      "testimony_excerpt": "While we have concerns about Section 4...",
      "bill_id": "HB1234",
      "confidence": 0.85
    }
  ]
}
```

## 🤗 Hugging Face Integration

DuckDB works natively with Hugging Face datasets:

```python
import duckdb

conn = duckdb.connect()

# Query HF dataset directly (no download!)
result = conn.execute("""
    SELECT * FROM read_parquet(
        'hf://datasets/CommunityOne/states-al-nonprofits-locations/data/train-*.parquet'
    )
    WHERE city = 'Birmingham'
    LIMIT 100
""").fetchdf()

# Works with Dataset Viewer
# Your Parquet files on HF are automatically searchable in the UI!
```

## 🎓 Use Cases

### 1. Lobbyist Identification

**Input**: Meeting testimony transcript  
**Output**: Named entities with roles

```python
# Vector search finds similar testimony
similar = analyzer.search_similar_testimony(query_embedding, limit=50)

# LLM extracts structured data
groups = llm.extract_interest_groups(bill, similar)

# Filter for registered lobbyists
lobbyists = [g for g in groups if g.lobbyist is not None]
```

### 2. Position Analysis

**Input**: Bill text + testimony  
**Output**: Support/oppose scores with confidence

```python
for group in groups:
    if group.stance_score > 0.5:
        print(f"✅ {group.group_name} SUPPORTS")
    elif group.stance_score < -0.5:
        print(f"❌ {group.group_name} OPPOSES")
    else:
        print(f"⚖️  {group.group_name} NEUTRAL/CONDITIONAL")
```

### 3. Tradeoff Detection

**Input**: Testimony with conditional language  
**Output**: Extracted compromises

```python
conditional_groups = [
    g for g in groups 
    if g.stance == "conditional" and g.tradeoff_notes
]

for group in conditional_groups:
    print(f"{group.group_name}:")
    print(f"  Position: {group.stance_score}")
    print(f"  Concessions: {group.tradeoff_notes}")
```

## 🔧 Troubleshooting

### Issue: Slow inference on Arc GPU

**Solution**: Make sure you're using OpenVINO, not standard transformers

```bash
# Check if OpenVINO is installed
python3 -c "from optimum.intel import OVModelForCausalLM; print('✅ OpenVINO available')"

# If not, install:
pip install optimum[openvino]
```

### Issue: "VSS extension not found"

**Solution**: Install manually

```bash
python3 << EOF
import duckdb
conn = duckdb.connect()
conn.execute("INSTALL vss")
conn.execute("LOAD vss")
EOF
```

### Issue: Out of memory

**Solution**: Use smaller models or reduce batch size

```python
# Use 3B instead of 8B
model_name = "meta-llama/Llama-3.2-3B-Instruct"

# Reduce context window
testimony = testimony[:10]  # Only use top 10 most relevant
```
