NOTE: We are switching to the GitHub Discussion Board. Google Group is depreciated and may take longer to receive responses than the Github Discussion Board. To ensure your questions are answered the earliest, please post on the GitHub Discussion Board instead (Or create an issue if a potential bug is speculated). A member will respond ASAP.

Welcome to Accel-Sim discussion group! Please, before posting your question, try to read first and go through the Accel-Sim manual:

https://accel-sim.github.io/#manual

If you do not find an answer to your question in the above manual, please search in previous asked questions on this group/or the closed Github issues (https://github.com/accel-sim/accel-sim-framework/issues). If you still cannot find an answer to your question, you're more than welcome to post on the GitHub Discussion Board.

If you use GPGPU-Sim 4.x, trace-driven simulation, or any of the Accel-Sim components in your research, please cite: Mahmoud Khairy, Jason Shen, Tor M. Aamodt, and Timothy G.
