Dear All, This is Henry. I am running full system simulation using Linux kernel and Parsec disk image on Garnet NoC. My running command is: ./build/X86/gem5.fast --outdir my_stats/X86_MOESI_hammer_streamcluster configs/example/fs.py --checkpoint-restore=1 --checkpoint-dir=checkpoints/x86-linux/16c-1GB/parsec_roi/simdev/x86-linux_16c-1GB_streamcluster --work-end-exit-count=100 --ruby --restore-with-cpu TimingSimpleCPU --num-cpus=16 --num-dirs=4 --mem-size=1GB --num-l2caches=16 --l1d_size=32kB --l1i_size=32kB --l1d_assoc=4 --l1i_assoc=4 --l2_size=128kB --l2_assoc=8 --network=garnet --topology=MeshDirCorners_XY --mesh-rows=4 --vcs-per-vnet=4 --disk-image=m5_system_2.0b3/disks/x86root-parsec.img --kernel=m5_system_2.0b3/binaries/x86_64-vmlinux-2.6.28.4-smp The simulation always terminates due to the fatal condition: build/X86/sim/serialize.hh:379: fatal: fatal condition !paramInImpl(cp, name, param) occurred: Can't unserialize 'root.globals:curTick' I thought it should be caused by cpt file, so my cpt file is: (curTick is only shown in this part) [cid:image001.png@01D8B7CA.DB6166A0] There is a full simulation log: gem5 version 21.2.1.1 gem5 compiled Aug 23 2022 10:23:13 gem5 started Aug 24 2022 14:43:22 gem5 executing on henry-virtual-machine, pid 102911 command line: ./build/X86/gem5.fast --outdir my_stats/X86_MOESI_hammer_streamcluster configs/example/fs.py --checkpoint-restore=1 --checkpoint-dir=checkpoints/x86-linux/16c-1GB/parsec_roi/simdev/x86-linux_16c-1GB_streamcluster --work-end-exit-count=100 --ruby --restore-with-cpu TimingSimpleCPU --num-cpus=16 --num-dirs=4 --mem-size=1GB --num-l2caches=16 --l1d_size=32kB --l1i_size=32kB --l1d_assoc=4 --l1i_assoc=4 --l2_size=128kB --l2_assoc=8 --network=garnet --topology=MeshDirCorners_XY --mesh-rows=4 --vcs-per-vnet=4 --disk-image=m5_system_2.0b3/disks/x86root-parsec.img --kernel=m5_system_2.0b3/binaries/x86_64-vmlinux-2.6.28.4-smp warn: dir_cntrl0.memory is deprecated.
