hi Chuanlei Zheng and Aslam O Alykum Amin
the output shown by Zheng using which command and either it need to modify some 
code or just getting it using Terminal command with different option. Zheng can 
you guide  and write the command.

For IPC, use the number of committed instructions.

Hi,



Sum of system.cpu**.num_insts doesn't equal to sim_insts?



sim_insts 1056981309                       # Number of instructions simulated

system.cpu0.num_insts 108073118                       # Number of instructions 
executed

system.cpu1.num_insts 105227026                       # Number of instructions 
executed

system.cpu2.num_insts 111365104                       # Number of instructions 
executed

system.cpu3.num_insts 101689390                       # Number of instructions 
executed

system.cpu4.num_insts 107883306                       # Number of instructions 
executed

system.cpu5.num_insts 107863273                       # Number of instructions 
executed

system.cpu6.num_insts 107858566                       # Number of instructions 
executed

system.cpu7.num_insts 107883876                       # Number of instructions 
executed



Sum of all num_insts is 857843659, less than sim_insts, this is strange. So 
which one can be used for calculate IPC?



Thank you
