Function Documentation

int ghost_omp_get_nested

(

)

Check whether nested parallelism is enabled.

Returns

1 if nested parallelism is enabled, 0 if not.

int ghost_omp_in_parallel

(

)

Check whether one is in an active parallel region.

Returns

1 if in parallel region, 0 otherwise.

int ghost_omp_nthread

(

)

Get the number of OpenMP threads.

Returns

The number of threads.

void ghost_omp_nthread_set

(

int

nthreads

)

Set the number of threads.

Parameters

nthreads

The number of threads.

void ghost_omp_set_dynamic

(

int

dynamic_threads

)

Indicates that the number of threads available in subsequent parallel region can be adjusted by the run time.

Parameters

dynamic_threads

0 implies no runtime adjustments, else runtime adjustments are enabled

void ghost_omp_set_nested

(

int

nested

)

En- or disable nested parallelism.

Parameters

nested

1 if nested parallelism should be en-, 0 if it should be disabled.

int ghost_omp_threadnum

(

)

Get the active thread number.

Returns

The thread number.
