-.Dt PMC_COUNTER_STUDY 1
-.Os
-.Sh NAME
-.Nm pmc_counter_study
-.Nd Perform various study's on a systems overall PMC's.
-.Sh SYNOPSIS
-.Nm
-.Sh DESCRIPTION
-The
-.Nm
-The pmc_counter_study program is designed to run various tests against
-your systems performance. 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)".
