Hello,
I created checkpoints using the following configuration build/X86/gem5.opt \ --outdir=./check_2-core-l1--l2-noruby/ \ configs/example/fs.py \ --kernel=/gem5-stable/full_system_images/x86-system/binaries/x86_64-vmlinux-2.6.22.9.smp \ --mem-size='2GB' \ --mem-type=DDR3_1600_x64 \ --sys-clock='3.7GHz' \ --cpu-clock='3.7GHz' \ --sys-voltage='0.7V' \ --script=./parsec-scripts/fluidanimate.rcS \ --num-cpus=2 \ --num-dirs=2 \ --l1i_size=32kB \ --l1d_size=32kB \ --caches \ --num-l2caches=2 \ --l2_size=2MB \ --l2cache \ --take-checkpoints=5089510440360,17442781 \ --max-checkpoints=10 \ --checkpoint-dir=/gem5-stable/fluid-check/fluid_analyse/check-inst_2-core-l1--l2-noruby/ \ I see that checkpoints are created using AtomicSimple cpu-type and the stats.txt file shows that both the cpus are active ( num_cycles simulated by cpu0 is 64699209 and cpu1 is 64664572). And then I tried to restore from the checkpoints using O3 cpu-type using the below command. But when I look at the simulation output in "stats.txt", I see only cpu0 is active (num_cycles simulated is 64602 for cpu0 and 0 for cpu1 ). All the statistics for cpu1(2nd core) are either 0 or nan. I looked at the simulation 'config.ini' and it says both the cpus are configured as O3. build/X86/gem5.opt \ --outdir=./restore_2-core-l1-l2-noruby-atomicTOdet-norub/ \ configs/example/fs.py \ --kernel=/gem5-stable/full_system_images/x86-system/binaries/x86_64-vmlinux-2.6.22.9.smp \ --script=./parsec-scripts/fluidanimate.rcS \ --mem-size='2GB' \ --num-cpus=2 \ --sys-clock='3.7GHz' \ --cpu-clock='3.7GHz' \ --sys-voltage='0.7V' \ --l1i_size=32kB \ --l1d_size=32kB \ --checkpoint-dir=/gem5-stable/fluid-check/fluid_analyse/check_2-core-l1--l2-noruby/ \ --checkpoint-restore=5 \ --rel-max-tick=17442781 \ --caches \ --num-l2caches=2 \ --l2_size=2MB \ --l2cache \ --cpu-type=detailed \ --restore-with-cpu=detailed \ Any insights or solutions to this problem would be of great help to me!
