The iterations pragma specifies the approximate number of loop iterations for the chosen loop.
Syntax
#pragma ibm iterations (iteration-count) <countable for/while/do loop>
where iteration-count represents a positive integral constant expression.
Notes
The compiler uses the information in the iteration-count variable to determine if
it is efficient to parallelize the loop.
