Hi Ayaz, Thanks for the help. I guess if we don't share anything between the cores then it will be the multi-processor platform, right? Btw, how to enable SMT? I looked through the se.py then look like you only need to use DerivO3CPU and just pass an array of the process in. However, I got this error `gem5.opt: build/X86/base/stats/group.cc:115: void Stats::Group::addStatGroup(const char*, Stats::Group*): Assertion `statGroups.find(name) == statGroups.end()' failed.` What is the correct way to do this?
