## Core Capabilities

### 1. Flash Attention Optimization

Flash Attention provides significant speedups through memory-efficient attention computation:

```javascript
// Flash Attention Configuration
class FlashAttentionOptimizer {
  constructor() {
    this.config = {
      // Block sizes optimized for GPU memory hierarchy
      blockSizeQ: 128,
      blockSizeKV: 64,

      // Memory-efficient forward pass
      useCausalMask: true,
      dropoutRate: 0.0,

      // Fused softmax for reduced memory bandwidth
      fusedSoftmax: true,

      // Expected speedup range
      expectedSpeedup: { min: 2.49, max: 7.47 },
    };
  }

  async optimizeAttention(model, config = {}) {
    const optimizations = [];

    // 1. Enable flash attention
    optimizations.push({
      type: "FLASH_ATTENTION",
      enabled: true,
      expectedSpeedup: "2.49x-7.47x",
      memoryReduction: "50-75%",
    });

    // 2. Fused operations
    optimizations.push({
      type: "FUSED_OPERATIONS",
      operations: ["qkv_projection", "softmax", "output_projection"],
      benefit: "Reduced memory bandwidth",
    });

    // 3. Memory-efficient backward pass
    optimizations.push({
      type: "MEMORY_EFFICIENT_BACKWARD",
      recomputation: "selective",
      checkpointing: "gradient",
    });

    return optimizations;
  }

  // Benchmark flash attention performance
  async benchmarkFlashAttention(seqLengths = [512, 1024, 2048, 4096]) {
    const results = [];

    for (const seqLen of seqLengths) {
      const baseline = await this.measureBaselineAttention(seqLen);
      const flash = await this.measureFlashAttention(seqLen);

      results.push({
        sequenceLength: seqLen,
        baselineMs: baseline.timeMs,
        flashMs: flash.timeMs,
        speedup: baseline.timeMs / flash.timeMs,
        memoryReduction: 1 - flash.memoryMB / baseline.memoryMB,
      });
    }

    return results;
  }
}
```

### 2. WASM SIMD Acceleration

WASM SIMD enables native-speed vector operations in JavaScript:

```javascript
// WASM SIMD Optimization System
class WASMSIMDOptimizer {
  constructor() {
    this.simdCapabilities = null;
    this.wasmModule = null;
  }

  async initialize() {
    // Detect SIMD capabilities
    this.simdCapabilities = await this.detectSIMDSupport();

    // Load optimized WASM module
    this.wasmModule = await this.loadWASMModule();

    return {
      simdSupported: this.simdCapabilities.supported,
      features: this.simdCapabilities.features,
      expectedSpeedup: this.calculateExpectedSpeedup(),
    };
  }

  async detectSIMDSupport() {
    const features = {
      supported: false,
      simd128: false,
      relaxedSimd: false,
      vectorOps: [],
    };

    try {
      // Test SIMD support
      const simdTest = await WebAssembly.validate(
        new Uint8Array([
          0, 97, 115, 109, 1, 0, 0, 0, 1, 5, 1, 96, 0, 1, 123, 3, 2, 1, 0, 10, 10, 1, 8, 0, 65, 0,
          253, 15, 253, 98, 11,
        ]),
      );

      features.supported = simdTest;
      features.simd128 = simdTest;

      if (simdTest) {
        features.vectorOps = [
          "v128.load",
          "v128.store",
          "f32x4.add",
          "f32x4.mul",
          "f32x4.sub",
          "i32x4.add",
          "i32x4.mul",
          "f32x4.dot",
        ];
      }
    } catch (e) {
      console.warn("SIMD detection failed:", e);
    }

    return features;
  }

  // Optimized vector operations
  async optimizeVectorOperations(operations) {
    const optimizations = [];

    // Matrix multiplication optimization
    if (operations.includes("matmul")) {
      optimizations.push({
        operation: "matmul",
        simdMethod: "f32x4_dot_product",
        expectedSpeedup: "4-8x",
        blockSize: 4,
      });
    }

    // Vector addition optimization
    if (operations.includes("vecadd")) {
      optimizations.push({
        operation: "vecadd",
        simdMethod: "f32x4_add",
        expectedSpeedup: "4x",
        vectorWidth: 128,
      });
    }

    // Embedding lookup optimization
    if (operations.includes("embedding")) {
      optimizations.push({
        operation: "embedding",
        simdMethod: "gather_scatter",
        expectedSpeedup: "2-4x",
        cacheOptimized: true,
      });
    }

    return optimizations;
  }

  // Run WASM SIMD benchmark
  async runBenchmark(config = {}) {
    const results = {
      matmul: await this.benchmarkMatmul(config.matrixSize || 1024),
      vectorOps: await this.benchmarkVectorOps(config.vectorSize || 10000),
      embedding: await this.benchmarkEmbedding(config.vocabSize || 50000),
    };

    return {
      results,
      overallSpeedup: this.calculateOverallSpeedup(results),
      recommendations: this.generateRecommendations(results),
    };
  }
}
```

### 3. Performance Profiling & Bottleneck Detection

```javascript

    ];

## Best Practices

### Performance Optimization Checklist

1. **Flash Attention**
   - Enable for all transformer-based models
   - Use fused operations where possible
   - Target 2.49x-7.47x speedup

2. **WASM SIMD**
   - Enable SIMD for vector operations
   - Use aligned memory access
   - Batch operations for SIMD efficiency

3. **Memory Optimization**
   - Apply int8/int4 quantization (50-75% reduction)
   - Enable gradient checkpointing
   - Use memory pooling for allocations

4. **Latency Reduction**
   - Keep MCP response <100ms
   - Use connection pooling
   - Batch tool calls when possible

5. **SONA Integration**
   - Track all optimization trajectories
   - Learn from successful patterns
   - Target <0.05ms adaptation time
