[gem5-users] Re: Run Timed Simulation (Stop After Certain Time)
You can call cpu.scheduleInstStop(, , ) So, you can set an initial instruction limit which will exit from the simulate() call. Then, you can reset the stats and set a new instruction limit with scheduleInstStop. Then, call simulate() again. When this second simulate returns you can dump the stats. You may or may not be able to do all this from se/fs.py, but it's pretty straightforward to write your own gem5 runscript. Cheers, Jason On Mon, Dec 6, 2021 at 6:41 PM Abdelrahman S.

Hi Prof. Jason, Thanks a lot for your response. The problem is not that we need to set one instruction limit but set one instruction limit, then reset the stats, and then terminate the simulation completely after the "total instruction limit". So, these are basically two termination points; one for warmup and the other for the actual simulation.

Hi Abdelrahman, I think you have the right approach. Is the simulation not exiting after the warmup_inst instructions? Cheers, Jason On Sat, Dec 4, 2021 at 11:43 PM Abdelrahman S.
