   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.

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.
