There are roughly 20-22 canned tests that -setup specific PMC's and then run various formulas on the output information. -These formulas can be found in Intel documentation "Using Intel Vtune -amplifier xe on NNN Generation Intel Core Processors". The NNN is either -2nd, 3rd or 4th generation i.e. Sandy Bridge, Ivy Bridge and Haswell. -Currently the program only works on these three Intel processor types. -You can see the complete list of formula's by running the program -with the -H option. If you know a formula name you can run it by -typing -e name. If you know a name and want what the formula is you -can run the program with -e name -h and the program will not run but -it will tell you what that name will do (if known). The -T option can -be used to test all PMC's that are known to your system. When running a -test you will want to specify -m N where N is the number of 1 second samples -to collect and analize (it bounds the time the test runs). Finally for -those that have there own ideas on what formulas that you want to run -you can type your own formula in with -E "formula". The formula can -declare directly the PMC's by name or you can use an abbreviation -%NNN. To find out the abbreviations on your system you may run -pmc_counter_study -L and it will tell you each PMC name and the -abbreviation you can use. An example of a formula of your own might -be -E "FP_ASSIST.ANY / INST_RETIRED.ANY_P" <or short hand on Haswell> --E " %176 / %150". You must have spaces between each entry and -you may use paraenthisis to prioritize the operators. Add (+), Subtract (-1), -Divide (/) and Multiplication (*) is supported. You may also introduce -constant numbers as well. So for example you can do a standard efficency -test like -E "UOPS_RETIRED.RETIRE_SLOTS / (4 * CPU_CLK_UNHALTED.THREAD_P)". - |
