This file contains wrapper functions for standard OMP functions, that work with and without OMP support. This saves the use of #ifdef statements around omp functions in the ARTS main code.

All functions start with arts_omp. Otherwise, names are the same as the standard OMP function names.

Definition in file arts_omp.cc.

Function Documentation

arts_omp_get_max_threads()

int arts_omp_get_max_threads

(

)

Wrapper for omp_get_max_threads.

This wrapper works with and without OMP support.

Returns

Maximum number of OMP threads, or 1 without OMP.

arts_omp_get_nested()

int arts_omp_get_nested

(

)

Wrapper for omp_get_nested.

This wrapper works with and without OMP support.

Returns

1 or 0, depending on if nested parallel execution is enabled or not.

arts_omp_get_thread_num()

int arts_omp_get_thread_num

(

)

Wrapper for omp_get_thread_num.

This wrapper works with and without OMP support.

Returns

ID number of the current thread, or 0 without OMP.

arts_omp_in_parallel()

bool arts_omp_in_parallel

(

)

Wrapper for omp_in_parallel.

This wrapper works with and without OMP support.

Returns

Returns true if the current region is running parallelized.

arts_omp_set_dynamic()

void arts_omp_set_dynamic

(

int

i

)

Wrapper for omp_set_dynamic.
