I am trying to determine control algorithms for an UAV performances using gem5 and have a question regarding the scripts. I have tried running my pre cross-compiled control binary in two different ways: 1º: -Launching the gem5 simulation and waiting for terminal input -creating a manual checkpoint -restoring from that checkpoint passing a simple script as parameter and executing it through m5 readfile |sh:
m5 resetstats &&./controlS && m5 dumpstats /sbin/m5 exit 2º: -Launching gem5 simulation passing the hack_back_ckpt.rcS -Restoring from the hack_back checkpoint with the above script as parameter And the results vary so much I would like to understand why.For example at the temporal aspect the hack back test took 0.010121 seconds while the manual checkpoint usually is around 0.002541.
