3 definitions found From Webster's Revised Unabridged Dictionary (1913) [web1913]: Locality \Lo*cal"i*ty\, n.; pl {Localitiees}. [L. localitas: cf F. localit['e].] 1. The state, or condition, of belonging to a definite place or of being contained within definite limits. It is thought that the soul and angels are devoid of quantity and dimension, and that they have nothing to do with grosser locality. --Glanvill. From WordNet r 1.6 [wn]: locality n : a surrounding or nearby region; "the plane crashed in the vicinty of Asheville"; "it is a rugged locality"; "he always blames someone else in the immediate neighborhood" [syn: {vicinity}, {neighborhood}, {neighbourhood}] From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]: locality 1. In sequential architectures programs tend to access data that has been accessed recently (temporal locality) or that is at an address near recently referenced data (spatial locality). This is the basis for the speed-up obtained with a {cache} memory. 2. In a multi-processor architecture with distributed memory it takes longer to access the memory attached to a different processor. This overhead increases with the number of communicating processors. Thus to efficiently employ many processors on a problem we must increase the proportion of references which are to local memory.
