/**
   Test: VIII_case1_iv   - forall test(Null)
   Purpose: To check that all threads execute all the iterations
   Type: Positive.
   How : - Declare a 2D array, a[N][THREADS], of integers of size N*THREADS.
           N is the number of iterations that will be used to test the forall. 
           This array will be automatically initialized to 0.
         - In the forall statement, every thread sets a[i][MYTHREAD] to 1,
           where i is  the current iteration.
         - At the end of the forall loop, check that every entry in this 2D 
           matrix is equal to 1.
