itimer_on_clkcpu

Description

This parameter is set to either 0 or 1, to determine whether itimer requests are queued on the clock processor or on the running processor, respectively.

Value

Default: 0

Range: 0 or 1

When to Change

If a process uses the gettimeofday(2) call to compare the accuracy of the itimer delivery, then you should set this parameter to 1, to take advantage of the clock processor. If the itimer request is for the purpose of implementing a user frequency-based scheduler, then set this parameter to 0 to queue the requests on the current running processor.
