This is a problem with X86 SE mode simulation, and not the GPU model itself.
It looks like there is sysconf call that is failing. I think a syscall trace may be useful as it can show you which system calls are being used, and which files the application is trying to open. I believe this error can happen when an open() call fails to find a certain file that should hold some configuration information. Have you tested with ROCm 1.6.x? That is the only version we support in gem5.

I tried to run a couple of apps there and they all had the same error. Basically I built the model as instructed and then did something like this. ./build/GCN3_X86/gem5.opt ./configs/example/apu_se.py -c /home/ComputeApps/lulesh-amp/lulesh . The error I got is "sysconf(NPROCESSORS_CONF) failed. : No such file or directory request to allocate mask for invalid number; abort : No such file or directory" The other apps also have the same issue. Could anyone point me as to what is the issue here or is my command incorrect?. Thanks Trinayan
