Hello Fernando, Thanks for your guidance.
Regards, Shervin --------------------------------------------------- Hello, It would be interesting comparing the performance stats produced by gem5 for each core. If they are approximately the same, McPAT is taking into account the physical distribution of the cores, distances, etc. If your results aren't wrong, they are very interesting!
