How this simulator combines GPU to implement simulation acceleration?

[sunkaixuan2018]

It seems that the network layer here is implemented by ns-3 with the system layer and workload layer like AstraSim. I notice that you said that GPU parallel acceleration can be used. Can you guide the location of the corresponding code and what functions are put on GPU?

For the network layer, we are using Multiverse-network instead of ns3. The system layer and workload layer still rely on ns3's event queue. Currently, Multiverse-network can be accelerated using GPU. By version 2.0, everything will be able to use GPU acceleration.
