32 $ sudo taskset -c 3 /home/testuser/pma_tools/jitter/jitter -i 30
33 Linux Jitter testing program version 1.9
35 The pragram will execute a dummy function 80000 times
36 Display is updated every 20000 displayUpdate intervals
37 Thread affinity will be set to core_id:7
38 Timings are in CPU Core cycles
39 Inst_Min: Minimum Excution time during the display update interval(default is ~1 second)
40 Inst_Max: Maximum Excution time during the display update interval(default is ~1 second)
41 Inst_jitter: Jitter in the Excution time during rhe display update interval. This is the value of interest
42 last_Exec: The Excution time of last iteration just before the display update
43 Abs_Min: Absolute Minimum Excution time since the program started or statistics were reset
44 Abs_Max: Absolute Maximum Excution time since the program started or statistics were reset
45 tmp: Cumulative value calcualted by the dummy function
46 Interval: Time interval between the display updates in Core Cycles
47 Sample No: Sample number
