- **-b USEC, --breaktrace=USEC**

  send break trace command when latency \> USEC

- **-c CLOCK, --clock=CLOCK**

  select clock: 0 = CLOCK\_MONOTONIC (default) 1 = CLOCK\_REALTIME

- **-d DIST, --distance=DIST**

  distance of thread intervals in us default=500

- **-i INTV, --interval=INTV**

  base interval of thread in us default=1000

- **-l LOOPS, --loops=LOOPS**

  number of loops: default=0 (endless)

- **-n, --nanosleep**

  use clock\_nanosleep

- **-p PRIO, --prio=PRIO**

  priority of highest prio thread

- **-q, --quiet**

  print only a summary on exit

- **-r, --relative**

  use relative timer instead of absolute

- **-t NUM, --threads=NUM**
