Hi Avadh
I have got not much idea about Simulation/Emulation modes. I was reporting the
outputs by the benchmarks' Printf statements at the end of execution on the
terminal. However I can see on your website you have posted ways to instrument
statistics through some python scripts. I will read that and get back to you
soon.
Sorry for not looking at that first:(

Are you calculating time while running in 'simulation' mode or just 'emulation'
mode. If you run it in just emulation mode then time will increase when you
increase number of cores because QEMU emulate each CPU in serial fashion and
keep the clock same as host machine. While in 'simulation' mode we clock each
CPU in one cycle and the VM time is also calculated based on 'cycles' in
simulation mode.
