3.10. parallel sections Construct

In the following example routines XAXIS, YAXIS, and ZAXIS can be executed concurrently. The first section directive is optional. Note that all section directives need to appear in the parallel sections construct.

//%compiler: clang
//%cflags: -fopenmp

/*
* name: psections.1
* type: C
*/
void XAXIS();
void YAXIS();
void ZAXIS();

void sect_example()
{
  #pragma omp parallel sections
  {
    #pragma omp section
      XAXIS();

    #pragma omp section
      YAXIS();

    #pragma omp section
      ZAXIS();
  }
}
