Hi Andrws, I'm running the simulations right now.. Could I ask how this makes a difference?
Also, (How) is this different from --cpu-type=arm_detailed? This will be my command line..do let me know if there is an issue with it 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=1GHz --cpu-type=timing --num-cpus=1 --caches --cpu-type=detailed R egards Guru On Thu, May 30, 2013 at 2:36 PM, Andrws Vieira <andrwsvie...@gmail.com>wrote: > Hi Guru, > > Try to put in the end of command line: *cpu-type=detailed* > * > * > Like this -> 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 -- > *cpu-type=detailed* > * > * > * > * > []'s > > > 2013/5/30 Guru Prasad <gurup...@buffalo.edu> > >> Here are some results >> >> Atomic >> 01 GHz >> Time taken :0.1000006s >> Number :142617 >> >> 04 GHz >> Time taken :0.1000003s >> Number :575327 >> >> 10 GHz >> Time taken :0.1000003s >> Number :1428815 >> >> >> >> Timing >> 01 GHz >> Time taken :0.1000310s >> Number :4597 >> >> 04 GHz >> Time taken :0.1000302s >> Number :4657 >> >> 10 GHz >> Time taken :0.1000297s >> Number :4643 >> >> >> Maybe this is how timing is supposed to work..I'm not sure.. >> I just didn't understand it and wanted to ask other users >> >> Regards >> Guru >> >> >> >> On Thu, May 30, 2013 at 2:09 PM, Guru Prasad <gurup...@buffalo.edu>wrote: >> >>> 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"?
