Hello Jason,
So I recompiled the SPARC configuration (now with the MinorCPU option in
‘build_options’ folder). Once that was done, I tried to run the hello world on
SPARC config using the “minor” CPU. Below is the error message I received. (I
tried running the same thing on “x86” architecture in GEM5 (after compiling for
X86) and it worked just fine with the MinorCPU).

One more question is, when I tried to run 2 “Hello_world” program on the SPARC
CPU using the “O3” model, it ran the program only on 1 CPU and just 1 workload
copy. The second CPU is present in the config.ini file, but it’s all 0 in the
stats.txt file for the second CPU. Below is the command I used for the
Multithreading option:
