+Following sections include sample calibration data measured on server running in
+one of the Intel Xeon Ice Lake testbeds.

+System-level Core Jitter
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+::
+
+ $ sudo taskset -c 3 /home/testuser/pma_tools/jitter/jitter -i 30
+ Linux Jitter testing program version 1.9
+ Iterations=20
+ The pragram will execute a dummy function 80000 times
+ Display is updated every 20000 displayUpdate intervals
+ Thread affinity will be set to core_id:7
+ Timings are in CPU Core cycles
+ Inst_Min: Minimum Excution time during the display update interval(default is ~1 second)
+ Inst_Max: Maximum Excution time during the display update interval(default is ~1 second)
+ Inst_jitter: Jitter in the Excution time during rhe display update interval. This is the value of interest
+ last_Exec: The Excution time of last iteration just before the display update
+ Abs_Min: Absolute Minimum Excution time since the program started or statistics were reset
+ Abs_Max: Absolute Maximum Excution time since the program started or statistics were reset
+ tmp: Cumulative value calcualted by the dummy function
+ Interval: Time interval between the display updates in Core Cycles
+ Sample No: Sample number
