priority inheritance         
<parallel> A technique for avoiding priority inversion by temporarily raising the prioriry of all processes that want to access a shared resource to the highest priority level of any of them. Priority inversion occurs where a low priority process, L is holding a resource required by a high priority process, H, but L is not running because a medium priority process, M is running. Under priority inheritance, L temporarily inherits H's priority, allowing L to run and release the resource H is waiting for. For example, an ambulance (H) is stuck behind a lorry (L) waiting at a junction (the shared resource) for a gap in a line of cars (M) using the junction. Applying priority inheritance, the cars give way to the lorry as they would to the ambulance, thus allowing the lorry and then the ambulance to use the junction. (2005-02-11)

In real-time computing, priority inheritance is a method for eliminating unbounded priority inversion. Using this programming method, a process scheduling algorithm increases the priority of a process (A) to the maximum priority of any other process waiting for any resource on which A has a resource lock (if it is higher than the original priority of A).

  • Pasqualotto, ''St. Mark writes his Gospel at the dictation of St. Peter'', 17th century.
  • The [[two-source hypothesis]], one of several built upon Marcan priority, holds that a hypothetical document (the [[Q source]]) was also used as a source by Matthew and Luke independently.
  • Two-Gospel (Griesbach) theory]], an alternative to Marcan priority, holds that Mark used Matthew and Luke as sources.
HYPOTHESIS THAT THE GOSPEL OF MARK WAS USED AS A SOURCE BY THE OTHER SYNOPTIC GOSPELS (MATTHEW AND LUKE)

Marcan priority is the hypothesis that the Gospel of Mark was the first of the three synoptic gospels to be written, and was used as a source by the other two (Matthew and Luke). It is a central element in discussion of the synoptic problem; the question of the documentary relationship among these three gospels.

Priority inheritance

In real-time computing, priority inheritance is a method for eliminating unbounded priority inversion. Using this programming method, a process scheduling algorithm increases the priority of a process (A) to the maximum priority of any other process waiting for any resource on which A has a resource lock (if it is higher than the original priority of A).

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 an elevated priority level. After executing its critical section and releasing its locks, the process returns to its original priority level.
