omp_get_num_threads (3f)

returns the number of threads currently in the team executing the parallel region from which it is called

Syntax

  interface
     integer function omp_get_num_threads ( )
     end function omp_get_num_threads
  end interface
  integer result
  result = omp_get_num_threads ( )

Description

  This function interacts with the omp_set_num_threads routine and the
  OMP_NUM_THREADS environment variable that control the number of threads in
  a team. If the number of threads has not been explicitly set by the user,
  the default is implementation dependent.

  This function binds to the closest enclosing PARALLEL directive.

Return Values

  This function returns the number of threads currently in the team executing
  the parallel region from which it is called.

  The function returns 1 if the call is made from the serial portion of a
  program, or from a nested parallel region that is serialized.
