mutual exclusion

(parallel, operating system)
(Or "mutex", plural: "mutexes") A collection of techniques for sharing resources so that different uses do not conflict and cause unwanted interactions. One of the most commonly used techniques for mutual exclusion is the semaphore.

The atomic instructions execute more than one basic operation (read, write, compare and swap) as a unit while maintaining the mutual exclusion and controlling the interrupt mechanism (Scogland, 2015).
The design of control strategies for mutual exclusion mechanisms can be considered as resolving a forbidden-string problem.
The first narrative structure, mutual exclusion, is concerned with "an opposition between two explanations or sets of events, one tagged as real or true, the other as illusory or false" (41).

Mutual exclusion: If the input edges are mutual exclusion operation led by lock and unlock, we should add concurrency operators of exclusion operation to process expressions.
One might say that the Tristero and the ghosts are rendered ontologically diaphanous through the activation of mutual exclusion: the alternation of existence and non-existence over the course of the narrative dilutes but intensifies their quality of being.
For a truly open theory of genre we need to go to 'The Problem of Speech Genres', a work of the 1950s where genre itself is finally predicated across the whole terrain of speech and writing, and 'pragmatic' and 'aesthetic' imperatives in the utterance are freed from the absolute of mutual exclusion into the nuanced relativity of interpenetration.
Since the copy is a time-consuming operation, it reduces the performance of simple synchronization or mutual exclusion primitives.
TPN can systematically analyze construction process models in a formal manner by utilizing several inherent properties including reachability and reversibility, absence of deadlock, liveness, boundedness and mutual exclusion. This paper shows, how the reachability of TPN can be utilized to analyze several aspects of construction projects.
He covers basic and advanced algorithms, data structure capabilities, scalable memory allocation, mutual exclusion, timing, and the task scheduler.
As Ruse illustrates (Chapter 12), the relation between Darwinism and religion usually was and still is one of mutual exclusion. A paradigmatic example of this is the replacement of traditional 'argument from design' (explanation of organisms' design-like features as created by God) with explanations in terms of natural selection.
Upon joining, the program gains access to a mutual exclusion lock (mutex).
