Table F-2 summarizes the the Compaq Fortran OpenMP Fortran API run-time library routines. These routines are all external procedures.
Table F-2 Summary of OpenMP Parallel Routines (TU*X only)
| Name | Description |
|---|---|
| omp_set_num_threads | Sets the number of threads to use for the next parallel region. |
| omp_get_num_threads | Gets the number of threads currently in the team executing the parallel region from which the routine is called. |
| omp_get_max_threads | Gets the maximum value that can be returned by calls to the omp_get_num_threads( ) function. |
| omp_get_thread_num | Gets the thread number, within the team, in the range from zero to omp_get_num_threads( ) minus one. |
| omp_get_num_procs | Gets the number of processors that are available to the program. |
| omp_in_parallel | Informs whether or not a region is executing in parallel. |
| omp_set_dynamic | Enables or disables dynamic adjustment of the number of threads available for execution of parallel regions. |
| omp_get_dynamic | Informs whether or not dynamic thread adjustment is enabled. |
| omp_set_nested | Enables or disables nested parallelism. |
| omp_get_nested | Informs whether or not nested parallelism is enabled. |
| omp_init_lock | Initializes a lock to be used in subsequent calls. |
| omp_destroy_lock | Disassociates a lock variable from any locks. |
| omp_set_lock | Makes the executing thread wait until the specified lock is available. |
| omp_unset_lock | Releases the executing thread from ownership of a lock. |
| omp_test_lock | Tries to set the lock associated with a lock variable. |
