I am having hardtime understanding the number of cycles from SE mode
statistcs
1)running with L1 only
build/X86/gem5.opt configs/example/se.py --cpu-type="detailed" --caches
--maxinsts=10000000 --cmd=bzip2/bzip2 --options="bzip2/input.program"
I am getting number of cycles as: system.cpu.numCycles
54101855
2)running with L1/L2 caches
build/X86/gem5.opt configs/example/se.py --cpu-type="detailed" --caches
--l2cache --maxinsts=10000000 --cmd=bzip2/bzip2
--options="bzip2/input.program"
I am getting number of cycles as: system.cpu.numCycles
82713679
does it make sense that performance get worse when adding L2 cache? why is
ipc worse? am I looking at wrong info to determine instruction/cycles?
any idea?
Thanks
Marcus
