In this exercise we look at memory locality properties of matrix computation. Th e following code is written in C, where element

s within the same row are stored contiguously. Assume each word is a 32-bit integer.
for (I=0; I<8; I++)
for (J=0; J<8000; J++)
A[I][J]=B[I][0]+A[J][I];

Answer:

Explanation:

temporal locality can be defined as: when a particular memory  is referenced or accessed several times  within a specific period of time. In the question, i think the variable that exhibit temporal locality are I, J and 0(all the variable). This is because the variable J and 0 are accessed several times within the loop. I would not have been part of it, but in the A[I][J]=B[I][0]+A[J][I], the variable "I" is also accessed in the addition. this is why it is part of the temporal locality.
