+high degree of parallelism can fully utilize the entire width of the machine. 
 The Loop Vectorizer increases the instruction level parallelism (ILP) by 
 performing partial-unrolling of loops.
 
 In the example below the entire array is accumulated into the variable 'sum'.
-This is inefficient because only a single 'adder' can be used by the processor.
