Hi all, I am trying to run Parsec on X86 FS multicore, using ruby memory model. My gem5 version is the latest stable version from May31, 2014. I successfully take a checkpoint at the beginning of ROI using "timing simple cpu”. When i try to restore from it using the detailed cpu, I get the following error: command line: /mnt/nokrb/fkaplan3/gem5/gem5-stable-May31_2014/build/X86/gem5.fast --outdir=/mnt/nokrb/fkaplan3/gem5/gem5-stable-May31_2014/RUNS/restore_4t/m5out_canneal --remote-gdb-port=0 /mnt/nokrb/fkaplan3/gem5/gem5-stable-May31_2014/configs/example/fs.py --disk-image=/mnt/nokrb/fkaplan3/gem5/full_system/disks/x86root-parsec.img --kernel=/mnt/nokrb/fkaplan3/gem5/full_system/binaries/x86_64-vmlinux-2.6.22.9.smp-configured -n 4 --caches --l2cache --num-l2caches=4 --l1d_size=16kB --l1i_size=16kB --l1d_assoc=2 --l1i_assoc=2 --l2_size=256kB --l2_assoc=4 --mem-size=1GB --checkpoint-dir=/mnt/nokrb/fkaplan3/gem5/gem5-stable-May31_2014/RUNS/ckpt_4t/m5out_canneal --checkpoint-restore=1 --cpu-clock=1.198GHz --cpu-type=detailed --ruby Global frequency set at 1000000000000 ticks per second info: kernel located at: /mnt/nokrb/fkaplan3/gem5/full_system/binaries/x86_64-vmlinux-2.6.22.9.smp-configured Listening for com_1 connection on port 3456 warn: Reading current count from inactive timer.

Could you help me on this issue? I also wonder if anybody has a working configuration with X86 FS running on multicores, using the detailed cpu. I have been using Ruby model as the classic memory model is said to have issues related to unimplemented x86 atomics.
