Hi Jason,
Thank you for reply me.
I am trying to run a program which mainly map "/dev/shm" and do some read write
on it. It works without gem5 but crash in gem5.
“
./build/X86/gem5.opt configs/example/se.py -c
"/home/ubuntu/taiyu/whisper_se/nstore/src/nstore" -o "-x10000 -k1000 -w -p0.2
-e1 --ycsb" --mem-size=8GB --cpu-type=DerivO3CPU --caches -n 4
“
And gem5 error report :
