## 📊 Core Concepts

### 1. Parallelism Types

```
Parallelism Taxonomy:
- Instruction-Level: Pipelining, superscalar, out-of-order
- Data Parallelism: SIMD, GPU, vector processors
- Task Parallelism: Multi-threading, multi-processing
- Pipeline Parallelism: Staged execution
```

### 2. Performance Metrics

| Metric | Definition | Formula |
|--------|------------|---------|
| Speedup | Ratio of sequential to parallel time | T₁ / Tₚ |
| Efficiency | Speedup per processor | Speedup / P |
| Scalability | Performance with increasing P | Strong/Weak scaling |
| Overhead | Additional parallel cost | Tₚ - T₁/P |

## 🔧 Components

### TypeScript SDK

```typescript
import {
  analyzeParallelism,
  optimizeThreads,
  vectorizeLoop,
  calculateSpeedup
} from '@wia/comp-004';

// Analyze parallelization potential
const analysis = analyzeParallelism({
  algorithm: 'matrix-multiply',
  dataSize: 10000,
  availableCores: 64,
  vectorWidth: 512 // AVX-512
});

console.log(`Max Speedup: ${analysis.maxSpeedup}x`);
console.log(`Optimal Threads: ${analysis.optimalThreads}`);
```
