-Following sections include sample calibration data measured on
-s11-t31-sut1 server running in one of the Intel Xeon Skylake testbeds as
-specified in `FD.io CSIT testbeds - Xeon Skylake, Arm, Atom`_.
-
-Calibration data obtained from all other servers in Skylake testbeds
-shows the same or similar values.

-
- $ sudo taskset -c 3 /home/testuser/pma_tools/jitter/jitter -i 20
- Linux Jitter testing program version 1.8
- Iterations=20
- The pragram will execute a dummy function 80000 times
- Display is updated every 20000 displayUpdate intervals
- 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
