Calculate the self$-$temporal reuse direction vector for array reference $A$ in the below code:

for $(\}$r$=0$;r$A,$ the solution $to$ the linear

system $to$ determine the reuse$-$direction vector, and explain the meaning $of$ the direction vector found.

For the same code above, calculate the spatial reuse direction vector for array reference $A.$ Consider

then two cases, when a cache line fits $4$ elements $ofA\text{'}s$ datatype and when the cache line fits $2$

elements $ofA\text{'}s$ type. $In$ which scenario will spatial reuse $be$ possible?

For the same code $as$ Problem $1,$ perform stride analysis assuming that each $of$ the four loops $is$ used $as$

the innermost loop.
