Hey all,
I am running PARSEC benchmark (blackscholes) on gem5 in x86 FS mode. After
taking a checkpoints at the beginning of ROI, I tried to run ROI portion in
detailed mode; however I kept getting this error message:
================================================================
build/X86_FS/gem5.opt -d results/blackscholes/ configs/example/fs.py

However, if i just run it in simple mode, using the following command:
build/X86_FS/gem5.opt -d results/blackscholes/ configs/example/fs.py
--checkpoint-restore=1
everything is fine and it'd run.
Anybody have any suggestions to fix my problem? That'd be greatly appreciated.
Thanks,
