SmartEdgeAI - (gem5)

This repo holds all scripts, commands, and logs for Phase 3.

Order of operations

1. Setup Environment

sh scripts/env.sh

Check logs: cat logs/env.txt - Should show environment variables and "READY" message

2. Build Workloads

sh scripts/build_workloads.sh

Check logs: Look for "All workloads compiled successfully!" and verify binaries exist:

ls -la /home/carlos/projects/gem5/gem5-run/

3. Test Single Run

sh scripts/run_one.sh tinyml_kws big high 0 1MB

Check logs:

• Verify stats.txt has content: ls -l /home/carlos/projects/gem5/gem5-data/SmartEdgeAI/results/tinyml_kws_big_high_l21MB_d0/stats.txt
• Check simulation output: cat logs/tinyml_kws_big_high_l21MB_d0.stdout.log
• Check for errors: cat logs/tinyml_kws_big_high_l21MB_d0.stderr.log

4. Run Full Matrix

sh scripts/sweep.sh

Check logs: Monitor progress and verify all combinations complete:

ls -la /home/carlos/projects/gem5/gem5-data/SmartEdgeAI/results/

5. Extract Statistics

sh scripts/extract_csv.sh

Check logs: Verify CSV was created with data:

head -5 /home/carlos/projects/gem5/gem5-data/SmartEdgeAI/results/summary.csv

6. Compute Energy Metrics

python3 scripts/energy_post.py

Check logs: Verify energy calculations:

head -5 /home/carlos/projects/gem5/gem5-data/SmartEdgeAI/results/summary_energy.csv

7. Generate Plots

python3 scripts/plot_epi.py
python3 scripts/plot_edp_tinyml.py

Check logs: Verify plots were created:

ls -la /home/carlos/projects/gem5/gem5-data/SmartEdgeAI/results/fig_*.png

8. Bundle Logs

sh scripts/bundle_logs.sh

Check logs: Verify bundled logs:

cat logs/TERMINAL_EXCERPTS.txt
cat logs/STATS_EXCERPTS.txt

9. (Optional) Generate Delta Analysis

python3 scripts/diff_table.py

Check logs: Verify delta calculations:

head -5 results/phase3_drowsy_deltas.csv

Paths assumed

• gem5 binary: /home/carlos/projects/gem5/build/ARM/gem5.opt
• config: scripts/hetero_big_little.py
• workloads: /home/carlos/projects/gem5/gem5-run/{tinyml_kws,sensor_fusion,aes_ccm,attention_kernel}

Output Locations

• Results: /home/carlos/projects/gem5/gem5-data/SmartEdgeAI/results/ (mirrored to results/)
• Logs: /home/carlos/projects/gem5/gem5-data/SmartEdgeAI/logs/ (mirrored to logs/)

Troubleshooting

• Empty stats.txt: Check gem5 simulation logs for errors
• Missing binaries: Re-run scripts/build_workloads.sh
• Permission errors: Ensure scripts are executable: chmod +x scripts/*.sh
• Path issues: Verify ROOT variable in scripts/env.sh points to correct gem5 installation
