🔧 How Multi-Tier Acceleration Works

The server intelligently routes operations through optimal acceleration tiers:

Small Data (< 10×10)
    ↓
  mathjs ────────────────→ Result
    Fast for small ops, no overhead

Medium Data (10-100)
    ↓
  WASM ──────────────────→ Result
    14x faster, single-threaded

Large Data (100-500)
    ↓
  WebWorkers ────────────→ Result
    56x faster, multi-threaded (3-4x × WASM)

Massive Data (500+)
    ↓
  WebGPU ────────────────→ Result
    5600x faster, GPU-accelerated (future)

Graceful Fallback Chain:

GPU → Workers → WASM → mathjs

If any tier fails, automatically falls back to the next tier. Never fails!

🐛 Troubleshooting

Worker Pool Issues

Workers Fail to Initialize

Symptoms:

[ERROR] Failed to create worker: Error: worker_threads not available
[ERROR] WorkerPool not initialized

Solutions:

Verify Node.js version:

node --version  # Must be v18.0.0 or higher

Check worker_threads support:

// test-workers.js
try {
  const { Worker } = require('worker_threads');
  console.log('✓ worker_threads available');
} catch (err) {
  console.error('✗ worker_threads not available:', err.message);
}

Rebuild native modules (if needed):
```
npm rebuild
npm install
```
Platform-specific issues:
- Docker: Ensure Node.js base image is v18+
- WSL/Windows: May need --experimental-worker flag (Node <16)
- Alpine Linux: Use node package, not nodejs-current

Worker Crashes Repeatedly

Symptoms:

[WARN] Worker exited unexpectedly { workerId: 'worker-0', exitCode: 1 }
[ERROR] Worker terminated due to reaching memory limit

Solutions:

Enable debug logging:
```
LOG_LEVEL=debug npm start
```

Increase Node.js memory limit:

node --max-old-space-size=4096 dist/index-wasm.js

Reduce worker count:
```
MAX_WORKERS=2 npm start
```

Check for WASM corruption:

# Rebuild WASM modules
cd wasm
npm install
npx gulp
cd ..
npm run generate:hashes

Monitor worker health:

ENABLE_PERF_LOGGING=true npm start
# Watch for patterns in worker exits

Operations Timeout

Symptoms:

[ERROR] Operation timed out after 30000ms
[ERROR] Task queue full, operation rejected

Solutions:

Increase operation timeout:
```
OPERATION_TIMEOUT=60000 npm start
```
Increase task timeout:
```
TASK_TIMEOUT=60000 npm start
```
Check input size (may be too large):
- Maximum matrix size: 1000×1000 (configurable via MAX_MATRIX_SIZE)
- Maximum array length: 100,000 (configurable via MAX_ARRAY_LENGTH)

Monitor worker pool status:

ENABLE_PERF_LOGGING=true npm start
# Check for: "Worker pool at capacity"

Scale up workers:
```
MIN_WORKERS=4 MAX_WORKERS=8 npm start
```

Worker Pool Not Scaling

Symptoms:

[DEBUG] Pool empty, creating worker on-demand
[INFO] WorkerPool initialized successfully { activeWorkers: 0 }

Solutions:

Verify MIN_WORKERS configuration:

# Set MIN_WORKERS=0 for auto-scaling
MIN_WORKERS=0 npm start

# Or keep workers warm
MIN_WORKERS=2 npm start

Adjust idle timeout:

# Workers terminate after 60s idle by default
WORKER_IDLE_TIMEOUT=120000 npm start  # 2 minutes

Monitor scaling behavior:

LOG_LEVEL=debug npm start
# Look for: "Pool empty, creating worker on-demand"
# Look for: "Terminating idle worker"

WASM Issues

WASM Integrity Verification Fails

Symptoms:

[ERROR] WASM integrity verification failed
[ERROR] Hash mismatch for wasm/build/release.wasm

Solutions:

Rebuild WASM modules:
```
cd wasm
npm install
npx gulp
cd ..
```
Regenerate hash manifest:
```
npm run generate:hashes
```
Disable integrity checks (development only):
```
DISABLE_WASM_INTEGRITY=true npm start
```

Verify file permissions:

ls -l wasm/build/*.wasm
# Should be readable by current user

WASM Module Not Loading

Symptoms:

[ERROR] Failed to load WASM module
[WARN] WASM not initialized, falling back to mathjs

Solutions:

Check WASM files exist:

ls wasm/build/
# Should contain: release.wasm, debug.wasm

Rebuild from scratch:

cd wasm
rm -rf node_modules build
npm install
npx gulp
cd ..

Verify AssemblyScript toolchain:

cd wasm
npx asc --version
# Should show AssemblyScript compiler version

Check Node.js WASM support:

// test-wasm.js
try {
  new WebAssembly.Module(new Uint8Array([0, 97, 115, 109, 1, 0, 0, 0]));
  console.log('✓ WASM supported');
} catch (err) {
  console.error('✗ WASM not supported:', err.message);
}

Acceleration Not Working

Check server startup logs:

MathJS MCP Server (Multi-tier Accelerated) running on stdio
Acceleration Status: 0% ops use acceleration  ← Should increase with usage

Common Issues:

Input sizes too small - Acceleration only activates above thresholds:
- WASM: 10×10+ matrices, 100+ elements
- Workers: 100×100+ matrices, 100k+ elements

WASM not initialized - Check startup logs:

[INFO] WASM modules initialized successfully
[INFO] WorkerPool initialized successfully { activeWorkers: 2 }

Using wrong entry point:

# ✓ Correct (with acceleration)
node dist/index-wasm.js

# ✗ Wrong (mathjs only)
node dist/index.js

Performance Not Improving

Verify using index-wasm.js not index.js
Check input sizes exceed acceleration thresholds (see docs/BENCHMARKS.md)

Monitor routing statistics in logs:

ENABLE_PERF_LOGGING=true npm start
# Look for: "WASM calls: 70%, mathjs calls: 30%"

Ensure worker threads are available (node --version >= 18)

Check system resources:

# Monitor CPU/memory during operations
top -p $(pgrep -f "node.*index-wasm")

Integration Tests Failing

npm install
npm run build:all
npm test

Expected output:

✓ All integration tests passed!
✓ WASM integration working correctly
Success rate: 100.0%

Common failures:

WASM modules not built:

npm run build:wasm
npm run generate:hashes

TypeScript compilation errors:

npm run type-check
# Fix any errors before running tests

Node.js version too old:

node --version  # Must be >=18.0.0
nvm install 18  # If using nvm

Memory Issues

High Memory Usage

Symptoms:

[WARN] Memory usage high: 1.2GB
[ERROR] JavaScript heap out of memory

Solutions:

Scale down workers:
```
MIN_WORKERS=0 MAX_WORKERS=2 npm start
```

Enable auto-scaling to zero:

MIN_WORKERS=0 WORKER_IDLE_TIMEOUT=30000 npm start

Increase Node.js heap:

node --max-old-space-size=2048 dist/index-wasm.js

Disable performance tracking:
```
DISABLE_PERF_TRACKING=true npm start
```

Memory Leaks

Symptoms:

Memory usage increases over time
Workers not being garbage collected

Solutions:

Monitor worker lifecycle:

LOG_LEVEL=debug npm start
# Look for: "Terminating idle worker"
# Check: workers.size in logs

Force garbage collection (debugging):
```
node --expose-gc dist/index-wasm.js
```

Reduce worker idle timeout:

WORKER_IDLE_TIMEOUT=30000 npm start  # 30 seconds

Getting Help

If you're still experiencing issues:

Enable debug logging:

LOG_LEVEL=debug npm start 2>&1 | tee debug.log

Collect system information:

node --version
npm --version
uname -a  # Linux/macOS
systeminfo  # Windows

Run diagnostic:

npm run type-check
npm test
npm run lint

Create an issue:
- URL: https://github.com/danielsimonjr/math-mcp/issues
- Include: Debug logs, system info, steps to reproduce
- Attach: Relevant error messages

Performance Tuning

For optimal performance, see:

Benchmark documentation: docs/BENCHMARKS.md
Threshold configuration: src/wasm-wrapper.ts:39-74
Worker pool tuning: Environment variables section above

Expected: 11/11 tests passing

🔧 Configuration

The server supports several environment variables for customization:

# Logging configuration
LOG_LEVEL=debug|info|warn|error    # Control log verbosity (default: info)

# Acceleration tier configuration
ENABLE_GPU=false                   # Enable WebGPU acceleration tier (default: false, not yet implemented)
ENABLE_WORKERS=true                # Enable WebWorkers acceleration tier (default: true)
ENABLE_WASM=true                   # Enable WASM acceleration tier (default: true)
NOTIFY_DEGRADATION=true            # Log when acceleration tier degradation occurs (default: true)

# Performance tuning
DISABLE_PERF_TRACKING=true         # Disable performance tracking for minimal overhead
ENABLE_PERF_LOGGING=true           # Enable periodic performance statistics logging

# Worker pool configuration
MIN_WORKERS=0                      # Minimum workers to keep alive (default: 2, set to 0 for auto-scaling)
MAX_WORKERS=8                      # Maximum concurrent workers (default: CPU cores - 1)
WORKER_IDLE_TIMEOUT=60000          # Idle timeout in ms before worker termination (default: 60000)
TASK_TIMEOUT=30000                 # Task timeout in milliseconds (default: 30000)

# Security limits
MAX_MATRIX_SIZE=1000               # Maximum matrix dimension (1000×1000)
MAX_ARRAY_LENGTH=100000            # Maximum array length for statistics
MAX_EXPRESSION_LENGTH=10000        # Maximum expression length (characters)
MAX_NESTING_DEPTH=50               # Maximum parentheses/bracket nesting
OPERATION_TIMEOUT=30000            # Operation timeout in milliseconds
