Linear loop transformations are useful in reductions of cache misses and increase possible parallelization. Consider the following two loops. Which of these loops would yield better performance? Why?

For I = 1, 1000

For J= 1, 1000

c(J) = c(J) + a(I,J)*b(J)

For J=1, 1000

For J=1, 1000

c(J) = c(J) + a(I,J)*b(J)
