Before you start

For CPU parallel run, install libomp-dev.

sudo apt install libomp-dev

Crafting topologies

A widely used topology can be downloaded from here:

https://www.rene-pickhardt.de/listchannels20220412.json

Then, conv.py can be used to convert the topology. Modify it according to your desires. The program can only handle a sorted list of edges in the ln_topology file. If you want to use larger topologies, create and convert accordingly. Number the vertices from 0. conv.py extracts nodes with more than 10 neighbors, you can change this parameter in the script.

Run

Run 10 simulations on 10 OpenMP threads:

export OMP_NUM_THREADS=10 && g++ -o sim sim.cpp -fopenmp && ./sim [NUM_OF_VERTICES] [NUM_OF_EDGES]
