🚨 What to Watch For

Normal Operation Indicators

  • GPU utilization: 30-60%
  • GPU memory: <2048 MiB (under 50% of 4096 MiB)
  • GPU temperature: <85°C
  • Trial completion: Every ~3-4 minutes
  • Sharpe ratios: 1.5-3.0 range
  • Loss decreasing: <0.1 typically

Warning Signs

  • ⚠️ GPU utilization: >90% sustained (possible deadlock)
  • ⚠️ GPU memory: >3500 MiB (risk of OOM)
  • ⚠️ GPU temperature: >85°C (thermal throttling)
  • ⚠️ No trial completion: >10 minutes (possible hang)
  • ⚠️ Sharpe ratios: <0.5 (poor hyperparameters)

Error Conditions

  • CUDA Out of Memory (OOM)
  • Process crashed (no PID in ps aux)
  • Auto-monitor stopped
  • GPU temperature: >95°C (emergency)

🔧 Troubleshooting

If DQN or Any Model Hangs

# Check if process is still alive
ps -p 3911478  # Replace with actual PID

# Check GPU status
nvidia-smi

# Check last log entries
tail -50 /tmp/tuning_run.log  # Or appropriate model log

# If truly hung (no progress for >15 minutes), kill and restart
kill -9 3911478  # Replace with actual PID

# Restart DQN manually
nohup /home/jgrusewski/Work/foxhunt/target/release/examples/tune_hyperparameters \
  --model DQN \
  --num-trials 50 \
  --epochs-per-trial 50 \
  --data-dir test_data/real/databento/ml_training \
  --output results/dqn_tuning_50trials.json \
  > /tmp/tuning_run.log 2>&1 &

echo $! > /tmp/dqn_tuning.pid

If CUDA Out of Memory (OOM) Occurs

# 1. Note which model failed
grep -i "out of memory\|OOM" /tmp/*tuning*.log

# 2. Kill the failed process
kill -9 $(cat /tmp/<model>_tuning.pid)

# 3. Edit tuning_config.yaml to reduce batch size
nano config/tuning_config.yaml

# Recommended batch size reductions:
# DQN: 256 → 128
# PPO: 256 → 128
# TFT: 128 → 64
# MAMBA-2: 256 → 128
# Liquid: 256 → 128

# 4. Restart the failed model
nohup /home/jgrusewski/Work/foxhunt/target/release/examples/tune_hyperparameters \
  --model <MODEL> \
  --num-trials 50 \
  --epochs-per-trial 50 \
  --data-dir test_data/real/databento/ml_training \
  --output results/<model>_tuning_50trials.json \
  > /tmp/<model>_tuning_run.log 2>&1 &

echo $! > /tmp/<model>_tuning.pid

If Auto-Monitor Stops

# Check if it's still running
ps aux | grep auto_monitor_and_launch.sh

# If not, restart it
nohup /home/jgrusewski/Work/foxhunt/scripts/auto_monitor_and_launch.sh \
  > /tmp/auto_monitor.log 2>&1 &

echo $! > /tmp/auto_monitor.pid

If Sequential Launcher Doesn't Start

# Check if DQN actually completed
ps -p 3911478  # Should return "no such process"
grep -c "Trial .* completed" /tmp/tuning_run.log  # Should be 50

# Manually launch sequential tuner
nohup /home/jgrusewski/Work/foxhunt/scripts/sequential_tuning_launcher.sh \
  > /tmp/sequential_tuning.log 2>&1 &

echo $! > /tmp/sequential_launcher.pid

📈 Results Extraction

When All Models Complete

# Extract best hyperparameters
cd /home/jgrusewski/Work/foxhunt
python3 scripts/extract_best_hyperparameters.py

# This will:
# 1. Parse all JSON result files in results/
# 2. Find best trial for each model (by Sharpe ratio)
# 3. Extract optimal hyperparameters
# 4. Update HYPERPARAMETER_TUNING_EXECUTION_REPORT.md

# View updated report
cat HYPERPARAMETER_TUNING_EXECUTION_REPORT.md

Manual Results Inspection

# Check if result files exist
ls -lh results/*_tuning_50trials.json

# View raw JSON (pretty-printed)
jq . results/dqn_tuning_50trials.json | less

# Find best trial manually
jq '[.trials[] | select(.status=="completed")] | max_by(.sharpe_ratio)' \
  results/dqn_tuning_50trials.json

# Extract specific hyperparameter
jq '[.trials[] | select(.status=="completed")] | max_by(.sharpe_ratio) | .hyperparameters.learning_rate' \
  results/dqn_tuning_50trials.json

Every 30 Minutes

# Quick status check
/home/jgrusewski/Work/foxhunt/scripts/quick_status.sh

# Or watch dashboard
watch -n 30 /home/jgrusewski/Work/foxhunt/scripts/dashboard_monitor.sh

Before Going to Sleep (18:00-20:00)

  • Verify DQN is progressing (should be ~30-40 trials by 20:00)
  • Check GPU temperature (<85°C)
  • Verify auto-monitor is running
  • Check no OOM errors in log

Morning Check (06:00-08:00)

  • Verify all models completed or check which is running
  • Check for any errors in logs
  • Run results extraction if complete

When Pipeline Completes (ETA 08:13)

# 1. Extract results
python3 scripts/extract_best_hyperparameters.py

# 2. Review report
cat HYPERPARAMETER_TUNING_EXECUTION_REPORT.md

# 3. Check all result files exist
ls -lh results/*_tuning_50trials.json

# 4. Verify 50 trials per model
for model in dqn ppo tft mamba2 liquid; do
  echo "$model: $(jq '[.trials[] | select(.status=="completed")] | length' results/${model}_tuning_50trials.json) trials"
done

📞 Emergency Contacts & Escalation

If System Becomes Unresponsive

# Check system load
uptime

# Check disk space
df -h

# Check memory
free -h

# Kill all tuning processes if necessary (LAST RESORT)
pkill -9 -f tune_hyperparameters

If Multiple OOM Errors Occur

This indicates insufficient GPU memory. Options:

  1. Reduce batch sizes more aggressively (32 → 16 → 8)
  2. Reduce epochs per trial (50 → 25)
  3. Use CPU instead of GPU (much slower, not recommended)

If Temperature Exceeds 95°C

# Emergency shutdown of all tuning
pkill -9 -f tune_hyperparameters

# Let GPU cool down (wait 10-15 minutes)
watch -n 5 nvidia-smi

# Check laptop cooling/vents
# Consider using cooling pad
# Reduce room temperature if possible
