Overhead-Research

Calculating the overhead cost of using eBPF tracing on throughput

File/Folder Descriptions

• README.md - This file

• exp.sh - Script to run the experiment

  • Arguments: run_id governor [powersave, performance, X]

  • Example: sudo ./exp.sh 1 powersave

  • Note: governor may not be accessible on all systems

  • Output: Logs/logs_run_id.txt

• process.py - Script to process the output of the experiment

  • Arguments: run_id iterations time_per_run workload_threads workload_depth governor

  • Example: python3 process.py A 10 20 500 1000 powersave

  • Output: Results/results_run_id.txt

  • Note: This script is run automatically as part of exp.sh

• visualizer.py - Script to visualize the results of the experiment

  • Arguments: run_id

  • Example: python3 visualize.py A

  • Outputs: Figures/run_id_probes.png and Figures/run_id_events.png

  • Note: This script is run automatically as part of `exp.sh

• Scripts/ - bpftrace scripts used to test the effect of increasing the number of context switch probes

• ProbeScripts/ - bpftrace scripts used to test different types of probes
