In
computer architecture a locale is an abstraction of the concept of a localized set of hardware resources which are close enough to enjoy uniform memory access.
For instance, on a
computer cluster
A computer cluster is a set of computers that work together so that they can be viewed as a single system. Unlike grid computers, computer clusters have each node set to perform the same task, controlled and scheduled by software. The newes ...
each node may be considered a locale given that there is one instance of the operating system and uniform access to memory for processes running on that node. Similarly, on an
SMP system, each node may be defined as a locale. Parallel programming languages such as
Chapel
A chapel (from , a diminutive of ''cappa'', meaning "little cape") is a Christianity, Christian place of prayer and worship that is usually relatively small. The term has several meanings. First, smaller spaces inside a church that have their o ...
have specific constructs for declaring locales.
