Don't calculate IPC scaling using stats["IPC"].mean() #17

Closed Jonathan3145 closed 4 years ago

Instead use something like

(stats["Useful Instructions"].sum() / stats["Useful Cycles"].sum())/ (self._stats_dict[ref_key].stats["Useful Instructions"].sum()/self._stats_dict[ref_key].stats["Useful Cycles"].sum())

Doing it this way ensures that the IPC is weighted by instructions per thread rather than being indifferent to relative workload
