### 5.6 Cross-Swarm Coordination
|
||
|
||
**Memory Sharing Protocol**:
|
||
```javascript
|
||
// Shared memory structure
|
||
const swarmMemory = {
|
||
phase: "current_sparc_phase",
|
||
progress: {
|
||
alpha: { completed: [], in_progress: [], blocked: [] },
|
||
beta: { completed: [], in_progress: [], blocked: [] },
|
||
gamma: { completed: [], in_progress: [], blocked: [] },
|
||
delta: { completed: [], in_progress: [], blocked: [] },
|
||
epsilon: { completed: [], in_progress: [], blocked: [] }
|
||
},
|
||
artifacts: {
|
||
specifications: "link_to_spec_docs",
|
||
implementations: "link_to_code_repos",
|
||
tests: "link_to_test_results",
|
||
benchmarks: "link_to_performance_data"
|
||
}
|
||
};
|
||
```
|
||
|
||
**Synchronization Points**:
|
||
1. **Phase Transition Gates**: All swarms must complete current phase tasks before proceeding
|
||
2. **Quality Gates**: Verification swarm approval required for production deliverables
|
||
3. **Integration Points**: Cross-swarm validation at module boundaries
|
||
4. **Performance Gates**: Benchmarks must meet thresholds before advancing
|
||
|
||

|
||
|
||
## 6. Verification & Validation Strategy
|
||
|
||
### 6.1 Mathematical Correctness
|
||
|
||
**Algorithm Validation**:
|
||
- Comparison against ground truth for small synthetic systems
|
||
- Convergence analysis with theoretical bounds verification
|
||
- Numerical stability testing across condition number ranges
|
||
- Error bound validation for each approximation method
|
||
|
||
**Test Matrix**:
|
||
```
|
||
System Types:
|
||
├── Well-conditioned ADD (condition number < 10^3)
|
||
├── Moderately conditioned ADD (10^3 ≤ κ ≤ 10^6)
|
||
├── Ill-conditioned ADD (κ > 10^6)
|
||
├── Directed graph Laplacians
|
||
├── Social network influence matrices
|
||
└── Economic flow networks
|
||
|
||
Problem Sizes:
|
||
├── Small (n ≤ 1000) - exact verification possible
|
||
├── Medium (1000 < n ≤ 10^5) - statistical validation
|
||
├── Large (10^5 < n ≤ 10^6) - performance validation
|
||
└── Huge (n > 10^6) - scalability testing
|
||
```
|
||
|
||
### 6.2 Performance Benchmarks
|
||
|
||
**Complexity Validation**:
|
||
```rust
|
||
#[bench]
|
||
fn bench_sublinear_scaling(b: &mut Bencher) {
|
||
let sizes = [1000, 5000, 10000, 50000, 100000];
|
||
for &n in &sizes {
|
||
let (matrix, vector) = generate_well_conditioned_add(n);
|
||
b.iter(|| {
|
||
let solver = HybridSolver::new();
|
||
solver.solve(&matrix, &vector, &default_options())
|
||
});
|
||
}
|
||
// Assert time complexity is o(n)
|
||
}
|
||
```
|
||
|
||
**Target Performance Metrics**:
|
||
- **Latency**: <1ms per incremental update for 10^6 node systems
|
||
- **Throughput**: >1000 queries/second on modern hardware
|
||
- **Memory**: O(nnz + k log n) space complexity where nnz = non-zeros
|
||
- **Accuracy**: Relative error <1e-6 for well-conditioned systems
|
||
|
||
### 6.3 Integration Testing
|
||
|
||
**Cross-Platform Validation**:
|
||
- Node.js environments (v16, v18, v20)
|
||
- Browser environments (Chrome, Firefox, Safari, Edge)
|
||
- Operating systems (Linux, macOS, Windows)
|
||
- Architecture targets (x86_64, aarch64, wasm32)
|
||
|
||
**Flow-Nexus Integration Tests**:
|
||
```javascript
|
||
describe('Flow-Nexus Integration', () => {
|
||
test('real-time cost propagation', async () => {
|
||
const swarm = await initializeSwarm();
|
||
const solver = new SublinearSolver(swarmGraph);
|
||
|
||
// Simulate dynamic cost updates
|
||
for (let update of costUpdateStream) {
|
||
await solver.updateCosts(update);
|
||
const routing = await solver.getRoutingRecommendations();
|
||
await swarm.updateRouting(routing);
|
||
}
|
||
|
||
expect(solver.getConvergenceMetrics()).toSatisfy(convergenceCriteria);
|
||
});
|
||
});
|
||
```
|
||
|
||
### 6.4 Quality Gates
|
||
|
||
**Phase Completion Criteria**:
|
||
|
||
1. **Phase S**: ✓ All algorithms mathematically specified with complexity analysis
|
||
2. **Phase P**: ✓ Core algorithms pass numerical accuracy tests with <1e-6 error
|
||
3. **Phase A**: ✓ Hybrid solver demonstrates >2x speedup on complex test cases
|
||
4. **Phase R**: ✓ WASM performance within 10% of native Rust implementation
|
||
5. **Phase C**: ✓ End-to-end integration tests pass with 100% success rate
|
||
|
||
**Continuous Quality Monitoring**:
|
||
- Automated regression testing on every commit
|
||
- Performance monitoring with alerts for >10% degradation
|
||
- Security scanning with zero critical vulnerabilities
|
||
- Code coverage maintenance >95% for core algorithms
