Logically speaking, the size of the work unit should not change
the semantics of the loop. That's just an implementation detail

Ok, therefore it means that, if at `j = 13 `i use a continue,
then the thread where I h

I didn't test this, but I'm pretty sure `continue` inside a
parallel foreach loop simply terminates that iteration early; I
don't think it wi

Consider :
for (int i = 0; i < max_value_of_i; i++) {
foreach ( j, dummyVar;
myTaskPool.parallel(array_to_get_j_from, my_workunitSize) {
if ( boolean_function(i,j) ) continue;
double d = expensiveFunction(i,j);
// ... stuff ...
}
}
