Also, in multi core simulations the number of committed instructions do not represent work fully as some instructions may be used for synchronization.

Because the real work done can be represented by committed instruction, and it is the same if one change the CPU frequency. What may change is the number of executed instructions (iew stage), because the dynamic behavior, i.e. the speculation, will be different with different CPU/cache freq ratio. Regards, -- Fernando A. Endo, PhD student and researcher Universit� de Grenoble, UJF France 2014-04-11 10:42 GMT+02:00 Heba Khdr <heba.k...@informatik.uni-karlsruhe.de>: Dear all, I have a question: I am running parsec applications using gem5 and for different freqeuencies in each experiment. When I increase the frequency, the number of committed instructions (which I got it from stats.txt) increase, till I exceed the frequency more than 1 Ghz, then the number of instructions will not increase. It will not saturated, but I will get the following: #instructions for 1.2 Ghz = #instructions for 0.6 Ghz. #instructions for 1.6 Ghz = #instructions for 0.8 Ghz. So, what do you think the problem is ?
