Large-scale workflow placement in serverless computing using integer nonlinear programming

Under revision for IEEE Access

How to use/Evaluate the results

a) Install the necessary dependencies:

pip install -r requirements.txt

b) Simple example: Run the placement problem

placement.py --num_run=0

Calculate the costs through simulation by running

selection_simulation.py --num_run=0

c) Scaling experiments:

For the first comparison against the heuristic run:

scaling_experiments.py

In the command line run

run_time_case_study_heuristic.bat

To visualize or show the data run

visualization_time_heuristic.py num_run=123

Change

For the second comparison against the centralized approach run:

scaling_experiments.py

In the command line run

run_time_case_study.bat

To visualize or show the data run

visualization_time.py num_run=126

d) Sensitivity to weights

To generate the different parameter files run

generate_different_weights.py

In the command line run

run_case_study.bat

To generate the images of the Paerto fronts run

visualization.py --num_run=2
