NAME
  runq - run queue

SYNOPSIS
  runq [-t] [-g]

DESCRIPTION
  With no argument, this command displays the tasks on the run queues
  of each cpu.
 
   -t  Display the timestamp information of each cpu's runqueue, which is the
       rq.clock, rq.most_recent_timestamp or rq.timestamp_last_tick value,
       whichever applies; following each cpu timestamp is the last_run or 
       timestamp value of the active task on that cpu, whichever applies, 
       along with the task identification.
   -g  Display tasks hierarchically by task_group.  Tasks in throttled groups
       are also displayed.

EXAMPLES
 Display the tasks on an O(1) scheduler run queue:
