Problem Statement
-----------------

        1. For the code given below, do the following:
                a. Identify the type of dependence in S1 (RAW, WAR, WAW,
                   loop carried/loop independent)
                b. compute the vectorization factor
                c. Speculate if the program can be 
                	i. vectorized
                	ii. parallelized
                
        2. Now vectorize and  parallelize the code with  gcc, and verify
           your observations.
        
        3. The number of iterations in  the given program is 203, which 
           is not  divisible by the  vectorization factor. Are  all the 
           iterations a part of the vectorized loop?                    
                  

Test case
---------

        int a[256];
        int main ()
        {
                int i;
                for (i=0; i<203; i++) {
                    a[i] = a[i] + 2;    /* S1 */
                }
                return 0;
        }
