%description
|
|
|
458dec |
The stalld program monitors the set of system threads,
|
|
|
458dec |
looking for threads that are ready-to-run but have not
|
|
|
458dec |
been given processor time for some threshold period.
|
|
|
458dec |
When a starving thread is found, it is given a temporary
|
|
|
458dec |
boost using the SCHED_DEADLINE policy. The default is to
|
|
|
458dec |
allow 10 microseconds of runtime for 1 second of clock time.
