[gem5-users] Error in elastic trace based simulation[Hidayatullah Chowdary]

Hi, I am having trouble in running trace based simulation. Non trace simulation is running fine. This is the command that I have used - build/X86/gem5.opt configs/example/se.py --elastic-trace-en --data-trace-file=deptrace --inst-trace-file=fetchtrace --cpu-type=DerivO3CPU --l1d_size=64kB

Hi folks, I had a really weird error in my simulations for a while now and finally think I figured out what caused it. So I'd like to share my thoughts and check if I'm right. First of all a rough description of my setup: I simulate a system with a number of systems that are connected via a
