[gem5-users] AMD GPU compute model does not work

Hi,

I built the gpu model based on instructions from http://gem5.org/GPU_Models
but cannot get it to run any application.


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"

Ticks: 4485602000

Exiting because exiting with last active thread context



The other apps also have the same issue. Could anyone point me as to what
is the issue here?.


Note that I have rocm 1.6 installed since the simulator mentions that is
the supported version.


Did anyone try to run the simulator after the latest update?. On top of
this on apu_se.py, I see some system specific paths set for the env
variable.

Do we change this?. Some pointers on getting the simulator working would be
really helpful for my research


Thanks ahead.
