but I still have one question about it.
1.Vtune windows has the ratio"Branch Misprediction per Branch Instruction Retired is 0.255 for functio check_3dd,
but Vtune Linux only show the function "check_3odd" occupy 88% total Branch mispredictedion. and no this option in the activity configuration / ratios
2.so I have to calculateratio by myself, "Branch Misprediction per Branch Instruction Retired=BR_INST_RETIRED.MISPRED / BR_INST_RETIRED.ANY"??
There is no difference in calculating the branch misprediction ratio on Windows and Linux. So, if there is no such a ratio in VTune for Linux (which I can't check at the moment), you can calculate it manually (i.e. using Excel spreadsheet). Was that the question?
