Phase 1 Progress - Core Dashboard Integration

✅ Completed (January 2, 2026)

1. NVML Dependency

  • ✅ Added nvml-wrapper = "0.10" to Cargo.toml
  • ✅ Created gpu-metrics feature flag (enabled by default)
  • ✅ Feature integrates with CUDA feature for full GPU support

2. GPU Monitoring Module

  • ✅ Created src/gpu/mod.rs with GPU tier classification
  • ✅ Created src/gpu/nvml_monitor.rs with full NVML integration
  • ✅ Supports automatic fallback to mock data when NVML unavailable
  • ✅ Detects TEE support (NVIDIA Confidential Computing on H100)
  • ✅ Real-time metrics: utilization, temperature, VRAM, power draw
  • ✅ Auto-classifies GPU tiers: Consumer, Professional, Enterprise, DataCenter

3. Metrics Aggregator

  • ✅ Created src/api/metrics_aggregator.rs
  • ✅ Aggregates data from 3 sources:
    • Blockchain: Stake, reputation, rewards (placeholders for contract calls)
    • Database: Job counts, earnings history, heartbeats
    • System: Real GPU metrics via NVML
  • ✅ Database queries implemented with sqlx
  • ✅ APY calculation framework
  • ✅ Uptime tracking based on heartbeats

4. Dashboard API Updates

  • ✅ Updated src/api/dashboard.rs to import MetricsAggregator
  • ✅ Added metrics_aggregator field to DashboardApiState
  • 🔄 IN PROGRESS: Updating handlers to use real data

🔄 In Progress

Updating Dashboard Handlers

Need to replace mock data with MetricsAggregator calls:

File: src/api/dashboard.rs

Handlers to Update:

  1. get_validator_status() - Lines 258-288

    • Replace hardcoded values with metrics_aggregator.get_validator_metrics(address)

  2. get_gpu_metrics() - Lines 291-319

    • Replace mock H100 data with metrics_aggregator.get_gpu_metrics()

  3. get_rewards_info() - Lines 318-332

    • Replace hardcoded rewards with metrics_aggregator.get_rewards(address)

Challenge: Need wallet address from request context

  • SDK passes address via headers: X-Wallet-Address
  • Need to extract address in handlers

⏳ Pending

Wire Blockchain Calls (Phase 1b)

Once handlers are updated, need to implement real Starknet contract calls:

File: src/api/metrics_aggregator.rs

  1. query_stake_info() - Line 312

    • Call ProverStaking.get_stake(address)
    • Parse stake amount and tier from contract

  2. query_reputation() - Line 322

    • Call ReputationManager.get_reputation(address)
    • Return reputation score (0-1000)

  3. query_onchain_rewards() - Line 330

    • Call ProverStaking.get_pending_rewards(address)
    • Call MiningRewards.get_claimable(address) if deployed

Implementation Notes:

  • Use existing StarknetClient from self.starknet
  • Contract ABIs needed for these calls
  • Error handling: Fall back to 0 values if contracts not deployed

📊 Current Status

What's Working

  • ✅ GPU metrics with NVML (real hardware detection)
  • ✅ Database queries for jobs and earnings
  • ✅ Mock data graceful fallback
  • ✅ Type-safe Rust implementation

What's Mock

  • 🔴 Stake amount (returns "0")
  • 🔴 Reputation score (returns 0)
  • 🔴 On-chain rewards (returns "0")

What Needs Testing

  • Database heartbeats table
  • Database reward_claims table
  • GPU detection on systems without NVIDIA GPUs
  • Contract addresses configuration

Next Steps

Immediate (Today)

  1. Update dashboard.rs handlers to call MetricsAggregator
  2. Add address extraction from request headers
  3. Test endpoints return real GPU data
  4. Test database queries work

Short-term (This Week)

  1. Implement Starknet contract calls in MetricsAggregator
  2. Deploy or verify contract addresses
  3. Test full E2E flow: UI → API → Blockchain
  4. Update UI_BACKEND_INTEGRATION_GAPS.md with progress

Blockers

  • Need DATABASE_URL for sqlx compile-time checks (non-blocking)
  • Need deployed contract addresses on Sepolia
  • Need contract ABIs for Starknet calls

Code Quality

Compilation Status

✅ All new modules compile successfully
⚠️  sqlx macros need DATABASE_URL (runtime OK)
⚠️  Some unused import warnings (pre-existing)

Test Coverage

  • ✅ Unit tests for GPU tier classification
  • ✅ Unit tests for mock GPU creation
  • ❌ Integration tests pending
  • ❌ E2E tests pending

Documentation

  • ✅ Full rustdoc comments in all new modules
  • ✅ Progress tracking in this file
  • ✅ Integration gaps documented in UI_BACKEND_INTEGRATION_GAPS.md

Estimated Completion

  • Phase 1a (GPU + Database): 80% complete
  • Phase 1b (Blockchain): 0% complete
  • Overall Phase 1: ~50% complete

ETA for Phase 1 completion: 4-6 hours remaining
