implicit parallelism - Free On-line Dictionary of Computing (26 May 2007) :

  implicit parallelism
  
     <parallel> A feature of a programming language for a parallel processing
      system which decides automatically which parts to
     run in parallel.
  
     The best way of providing implicit parallelism is still (1995)
     an active research topic.  The problem is to generate the
     right number of parallel tasks of the right size (or
     "granularity").  Too many tasks and the system gets bogged
     down in house-keeping, or memory for waiting tasks runs out,
     too few tasks and processors are left idle.
  
     The best performance is usually achieved with explicit parallelism
      where the programmer can annotate his program to
     indicate which parts should be executed as independent
     parallel tasks.
