The Free On-line Dictionary of Computing (30 December 2018):

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.
