Hi Andreas, The output of my program is the same. I'm running primality test program that is given a time bound.
I t returns the last number that it tested when it runs out of time. I would expect the last number computed to differ based on frequency specified while running Gem5. This differs significantly when using both, Atomic model and O3.. But regardless of the --clock parameter, timing model always gives me results that are very close. My command line parameters are build/ARM/gem5.fast configs/example/fs.py --kernel /home/guru/gem5/kernel/linux-3.3-armdroid/vmlinux --disk-image /home/guru/gem5/gem5-stable/system/disks/android_jb_pa_spec.img --machine-type=VExpress_EMM --clock=4GHz --cpu-type=timing --num-cpus=1 I am working with a slightly outdated gem5 source..I believe my revision is 9197 On Thu, May 30, 2013 at 1:57 PM, Andreas Hansson <andreas.hans...@arm.com>wrote: > Hi Guru, > > Could you perhaps elaborate on "same results"?
