Recommendation: ✅ local_gpu

Total time: 0.101 hours (6.1 minutes)

|
|
Cloud cost: $0.053 (AWS g4dn.xlarge @ $0.526/hr)

1. ❌ MAMBA-2 Benchmark Missing
|
|
Impact: Cannot validate 4-6 week training timeline
|
|
Risk: MAMBA-2 may be slower than estimated (SSM complexity)
|
|
Module exists: ✅ ml/src/benchmark/mamba2_benchmark.rs (21KB)
|
|
|
|
2. ❌ TFT Benchmark Missing
|
|
Impact: Cannot validate memory constraints (1.5-2.5GB on 4GB GPU)
|
|
Risk: TFT may require batch_size=2, doubling training time
|
|
Module exists: ✅ ml/src/benchmark/tft_benchmark.rs (23KB)
|
|
|
|
3. ⚠️ DQN Stability Issue
|
|
Impact: Loss diverging, cannot deploy to production
|
|
Risk: Requires hyperparameter tuning + retraining (1-2 days)
|
|
Root cause: Unknown (learning rate / target update / replay buffer)

Root Cause: gpu_training_benchmark.rs coordinator only calls DQN/PPO benchmarks
|

|
Code Analysis (ml/examples/gpu_training_benchmark.rs:204-220):
|
|
✅ Step 3: Run DQN benchmark ← IMPLEMENTED
|
|
✅ Step 4: Run PPO benchmark ← IMPLEMENTED
|
|
❌ Step 5: Run MAMBA-2 benchmark ← MISSING
|
|
❌ Step 6: Run TFT benchmark ← MISSING
|
|
|
|
Required Changes:
|
|
1. Add imports: Mamba2BenchmarkRunner, TftBenchmarkRunner
|
|
2. Add methods: run_mamba2_benchmark(), run_tft_benchmark()
|
|
3. Update BenchmarkReport struct (add mamba2_results, tft_results fields)
|
|
4. Update compute_aggregate_metrics() (4 models instead of 2)
|
|
5. Update print_summary() (display all 4 models)
|
|
|
|
Estimated effort: 100-150 lines of code (copy-paste from DQN/PPO)

|
✅ DQN/PPO benchmarked (Wave 152)
|
|
❌ MAMBA-2/TFT not benchmarked
|
|
❌ Cannot make informed 4-6 week training decision

All 4 models: ⚠️ LOW (extrapolated, 41 min estimate)
|
|
|
|
Recommendation: Run full benchmark suite BEFORE committing to 4-6 week training.
|
|
|
|
Risk Assessment:
|
|
HIGH: TFT memory bottleneck (1.5-2.5GB on 4GB GPU)
|
|
MEDIUM: DQN divergence (requires fixing)
|
|
LOW: GPU thermal throttling (24h+ training)
|
|
|
