Hi, I am trying to run a OpenMP code in X86-FS mode using following command command line: ./build/X86_MESI_Two_Level/gem5.opt --verbose configs/example/fs.py --cpu-type=TimingSimpleCPU --num-cpus=4 --caches --l1d_size=64kB --l1i_size=64kB --l2cache --l2_size=256kB --cacheline_size=64 --mem-size=2048MB --disk-image=/nfs/div1/adeshpan/arch/x86_disks/disks/x86root-parsec_ad.img --kernel=/nfs/div1/adeshpan/arch/x86_disks/binaries/x86_64-vmlinux-2.6.22.9
Then on simulator command prompt I added this ENV variable export OMP_NUM_THREADS=4 After executing the benchmark, in the stats.txt file, I observe only system.cpu0. stats have any value. Stats for cpu1, cpu2, cpu3 are all 0. After reading some of the previous posts I added another ENV variable export GOMP_CPU_AFFINITY="0 1 2 3" and then re-ran the benchmark. Even after this only cpu0 stats gets reflected, All cpu1,2,3 stats are 0. How do I make sure that when I want to use 4-threads, all the cpu cores are used. Any help is appreciated. Regards, Aditya
