  From  WordNet  r  1.6  [wn]: 
 
  granularity 
  n  :  the  quality  of  being  composed  of  relatively  large  particles 
  [syn:  {coarseness},  {graininess}] 
 
  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
 
  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.
