Hi Jason,
Thank you for your reply. I am using the latest version 20.3. I have just
double-checked the memory usage info of gem5. It showed that memory usage is
about 10GB, while I run gem5 on a 128GB memory server. I don't think my system
ran out of memory. I am confused about it.

主题: [gem5-users] Re: gem5 aborted when increase mem-size in FS mode
Hi Yifan,
Is it possible that your system is running out of memory? It's possible this is
a gem5 bug (what version are you using?), but I haven't heard of this issue
before.
Cheers,
Jason

Hi all,
I am trying to run my own program (training a tiny vgg16 CNN model using CPU)
in FS mode. I have created my own disk image and installed python3 and pytorch
on it. My command line is as bellow：
build/X86/gem5.opt configs/example/fs.py --kernel=binary/vmlinux-5.2.4
--disk-image=disk/linux-x86.img -n 2 --caches --l2cache --mem-size=4GB
If I set the mem-size small, like 512MB, 1GB, 2GB, my program could run
normally but would fail due to the small memory. On the other hand, if I
increase the mem-size, my program could not run and gem5 aborted (core dump).
Could anyone give me some advice? Thanks.
Best regards,
Yifan
