Intro | Prospective project Idea

[Kushagra Kinra]

Hello, I am Kushagra a second year computer science and enginnerign student at IITJ, India. I have used NS3 extensively for a network optimisation problem statement given by Arista Networks and at that time I felt  the need for multi-threading. I tried different adapters but felt a need for core engine to be multi-threaded by processing independent events.
I would love to contribute to NS3 in this year's GSoC.

Hi Kushagra, I agree that multi-threading in the core would be nice if it were able to improve execution time, but there are some hard problems to overcome to make that work in general.  Here is some older work on that topic: [1].  Instead, ns-3 decided to focus on parallelization via MPI [2] (although the simulation problem being studied has to be amenable to this kind of parallelization) and on using multiple cores or systems to run experiments in parallel (e.g., the SEM tool [3]).

For Google Summer of Code, I suggest to review the project ideas listed by the prospective mentors and reach out to one of them to get started on developing an application.
