In real-time computing, priority inheritance is a method for eliminating priority inversion problems. Using this programming method, a process scheduling algorithm will increase the priority of a process to the maximum priority of any process waiting for any resource on which the process has a resource lock.
The basic idea of the priority inheritance protocol is that when a job blocks one or more high priority jobs, it ignores its original priority assignment and executes its critical section at the highest priority level of all the jobs it blocks. After executing its critical section, the job returns to its original priority level.
Famous quotes containing the words priority and/or inheritance:
“It can be fairly argued that the highest priority for mankind is to save itself from extinction. However, it can also be argued that a society that neglects its children and robs them of their human potential can extinguish itself without an external enemy.”
—Selma Fraiberg (20th century)
“Someone in the crowd said to him, “Teacher, tell my brother to divide the family inheritance with me.” But he said to him, “Friend, who set me to be a judge or arbitrator over you?””
—Bible: New Testament, Luke 12:13,14.
