reduction and task

[fanbin]

OpenMP Spec 3.0 [99:25-26] says "A list item that appears in a reduction clause of the innermost enclosing worksharing or parallel construct may not be accessed in an explicit task."

Does it mean that code like below is illegal?

Code: Select all

#pragma omp parallel sections reducton(+:k)
{
#pragma omp section
  {
    // blah blah
  }
#pragma omp section
  {
#pragma omp task shared(k)
    {
      k = ...
    }
#pragma omp taskwait
  }
}


Thanks!

I think this code should be non-conforming. The section constructs are not a worksharing constructs: the parallel sections construct is the innermost worksharing or parallel construct in this case.
