The stalld program (which stands for 'stall daemon') is a

The stalld program is a mechanism to prevent the starvation of operating system threads in a Linux system.
|
||||||
mechanism to prevent the starvation of operating system threads in a
|
|
||||||
Linux system. The premise is to start up on a housekeeping cpu (one
|
|
||||||
that is not used for real-application purposes) and to periodically
|
|
||||||
monitor the state of each thread in the system, looking for a thread
|
|
||||||
that has been on a run queue (i.e. ready to run) for a specifed length
|
|
||||||
of time without being run. This condition is usually hit when the
|
|
||||||
thread is on the same cpu as a high-priority cpu-intensive task and
|
|
||||||
therefore is being given no opportunity to run.
|
|
||||||
When a thread is judged to be starving, stalld changes
|
|
||||||
that thread to use the SCHED_DEADLINE policy and gives the thread a
|
|
||||||
small slice of time for that cpu (specified on the command line). The
|
|
||||||
thread then runs and when that timeslice is used, the thread is then
|
|
||||||
returned to its original scheduling policy and stalld then
|
|
||||||
continues to monitor thread states.
|
|
||||||
There is now an experimental option to boost using SCHED_FIFO. This
|
|
||||||
logic is used if the running kernel does not support the
|
|
||||||
SCHED_DEADLINE policy and may be forced by using the -F/--force_fifo
|
|
||||||
option.
