Thread의 우선순위

쓰레드의 우선순위는 O/S 스케쥴러가 쓰레드의 실행 시점을 Scheduling하기위해 참조하는 지표로, 프로그래머가 쓰레드를 생성할 때 지정할 수 가 있다.

프로그래머는 쓰레드의 역할에 따라 적절한 우선순위를 부여하여, 어플리케이션이 목적하는 바를 안정적으로 수행할 수 있도록 해야 겠다.

 

스레드의 우선권(priority)는 0~9와 같이 구분되며, 통상 O/S에서는 레벨 값이 낮을 수록 우선권이 높다.

우선권이 높다는 것은 여러 스레드가 대기(ready)하고 있을 때 우선실행 (preempt)될 수 있는 권한이 있다는 의미이다. 

 

우선순위와 Thread의 동작 방식의 예상

♦우선권이 가장 높은 쓰레드가 정지상태/소멸상태로 천이하지 않고 있다면,  스케쥴러는 그 쓰레드만 실행시킬 것이다. 

⊗ 이런 경우에는 아무래도 모종의 조치를 취해 주어야 할 듯 합니다.

♦레벨이 같은 스레드들이 운행되고 있다면 스케쥴러는 균등하게 시간을 분배해 쓰레드들이 번갈아 실행되도록 할 것이다.
