Description

1

Parallel site

Represents the location and associated call stack of the parallel site. No task annotations were executed in the dynamic extent of the active parallel site.

Example

int global;
void main()
{
    ANNOTATE_SITE_BEGIN(reuse_site);  // Parallel site
        assert(global == 111);
        global = 222;
    ANNOTATE_SITE_END();
}

In this example, the site begin and site end annotations are present, but the execution paths within the parallel site do not execute any task annotations.

Some Possible Correction Strategies

Check the execution paths within the parallel site and add task annotations to mark at least one task.
