Hi Hoa Nguyen, A bit sad when some features I want will only be supported from 20.2 version (SMT, multicore DerivO3CPU). Do the gem5 team have any plan on when the next version will be released?
About the stats error, I use the same version and cmd as the first email. I will retype it here for convenience. Cmd: `./build/X86/gem5.opt configs/tutorial/two_core.py` gem5 version 20.1 gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04) python 2.7.17 The error log: gem5.opt: build/X86/base/stats/group.cc:115: void Stats::Group::addStatGroup(const char*, Stats::Group*): Assertion `statGroups.find(name) == statGroups.end()' failed.
