Hi, Nilay
Thanks! Yes, after get the data by multiplying the cycle_period and
ruby_cycles, I think I can explain
the results.
I ran the application using script and dumpresetstats before running the
user application.
It seems that dumpresetstats doesnot work for ruby. How to solve this problem?
The data in ruby.stats
The ruby cycle_period: 500, and Ruby_cycles: 7095735495.
The result of multiplying them is: 3547867747500
The data in stats.txt are:
Data by first dumpresetstate:
---------- Begin Simulation Statistics ----------
sim_seconds 2.432645 #
Number of seconds simulated
sim_ticks 2432644795000
The data after finish the execution and exit gem5:
---------- Begin Simulation Statistics ----------
sim_seconds 1.113264 #
Number of seconds simulated
sim_ticks 1113263905500 #
Number of ticks simulated
final_tick 3547867747500

Is it not evident from the data the these two can be different. You need
to multiply the ruby cycles with some constant (cycle period) to get the
actual time elapsed.
