Define the word granularity

granularity
     n : the quality of being composed of relatively large particles
         [syn: coarseness, graininess]

granularity
     
         The size of the units of code under
        consideration in some context.  The term generally refers to
        the level of detail at which code is considered, e.g. "You can
        specify the granularity for this profiling tool".
     
        The most common computing use is in parallelism where "fine
        grain parallelism" means individual tasks are relatively small
        in terms of code size and execution time, "coarse grain" is
        the opposite.  You talk about the "granularity" of the
        parallelism.
     
        The smaller the granularity, the greater the potential for
        parallelism and hence speed-up but the greater the overheads
        of synchronisation and communication.
