The article has two major claims:

• C1: We develop a multi-fidelity modeling framework that enables simulation of multi-traffic simultaneously over the interconnect network, including inter-process communication and I/O traffics.
• C2: We conduct simulation studies of hybrid workloads composed of traditional HPC applications and emerging ML applications on a 1,056-node Dragonfly system with various configurations.

Figure 10, 11, 12, 13 from the paper can be reproduced. The mapping between claims, experiments, figures and tables are resumed in the following table.

To compile the program:

1. cd source_codes
2. ./compile_script.sh

To run all experiments and process its results, type the following:

3. cd source_codes/experiments
4. ./run_exp.sh

Wait all experiments to finish and process their results at once, type the following:

5. cd source_codes/experiments
6. ./draw_plots.sh

The expected runtime of each experiment is detailed in the following table:

Once all experiments have been run, you can find Figure 11 under linkfig/ folder, and Figure 10, 12, 13 under appfig/ folder.
