FUNCTIONS_OPENMP
  Demonstrate a few of OpenMP's library functions.

  While NOT in a parallel region:

  omp_get_max_threads ( ) = 12
  omp_get_num_threads ( ) = 1
  omp_get_thread_num ( ) =  0
  omp_get_num_procs ( )   = 12
  omp_get_wtime ( ) =       1.43745e+07

  While NOT in a parallel region,
  after calling omp_set_num_threads ( 5 ):

  omp_get_max_threads ( ) = 5
  omp_get_num_threads ( ) = 1
  omp_get_thread_num ( ) =  0
  omp_get_num_procs ( )   = 12
  omp_get_wtime ( ) =       1.43745e+07


  Enter a parallel region.
  after calling omp_set_num_threads ( 3 ):

  Enter a parallel region.
  omp_get_thread_num ( ) =  0

  after calling omp_set_num_threads ( 3 ):


  While in a parallel region,
  printing from a single thread:

  omp_get_max_threads ( ) = 3
  omp_get_thread_num ( ) =  2
  omp_get_num_threads ( ) = 3
  omp_get_thread_num ( ) =  0
  Enter a parallel region.
  after calling omp_set_num_threads ( 3 ):

  omp_get_num_procs ( )   = 12
  omp_get_thread_num ( ) =  1
  omp_get_wtime ( ) =       1.43745e+07

  omp_get_wtime estimates duration of sleep(5) as 5.00016 seconds.
