This assignment is to evaluate the impact of different cache configurations on the

execution times of applications. You will run three benchmark traces provided for you.

Trace$1.$din, Trace$2.$din and Trace$3.$din.

You specify these file names along the path name as the input to Dinero IV$.$ You will

evaluate L$1$ and L$2$ misses when adjusting the cache configurations of L$2$ by adjusting L$1$

configuration. Both L$1$ and L$2$ use write through and use LRU replacement algorithm.

First, you should evaluate just L$1$ cache, below are the L$-1$ configurations you must vary.

Size of L$1-$I and L$1-$D is fixed to $16$KB$.$ Block sizes should be configured as $32$ Bytes

and $64$ Bytes. Associativity as $1-$way, $2-$way and $4-$way.

Then, add L$2$ Cache of size $128$KB$,$ repeat above tests. The block sizes and associativity

should match the L$1$s

OR follow the table for all the combinations you should be testing:

L$1$ size Associativity Block size

$16$ KB $132$ B

$16$ KB $232$ B

$16$ KB $432$ B

$16$ KB $164$ B

$16$ KB $264$ B

$16$ KB $464$ B

L$1$ & L$2$ size Associativity Block size

$16$ KB & $128$ KB $132$ B

$16$ KB & $128$ KB $232$ B

$16$ KB & $128$ KB $432$ B

$16$ KB & $128$ KB $164$ B

$16$ KB & $128$ KB $264$ B

$16$ KB & $128$ KB $464$ B

Cycles on Hit and Miss

The table below indicates the number of processor clocks for a hit in each of the L$2$ cache

configurations. L$1$ hit takes $1$ cycle. If there is no L$2$ cache, L$1$ miss penalty is $60$ cycles.

L$2$ miss penalty is also $60$ cycles.

$2$

Size $\backslash$ Associative $1-$way $2-$way $4-$way

$128$ Kbyte $456$

Use the cache simulator to get the L$2$ & L$1$ miss rate and compute the CPI for each

benchmark$-$cache configuration combination $($CPI equation can be found in class notes

and textbook$).$ Use the cycle count for hits and misses of the L$2$ & L$1$ and determine

which cache configuration will give the best performance $($i$.$e$.,$ the lowest CPI$)$ for each

benchmark.

You are required to make a shells script in order to easily run all possible configurations,

submit this shell script with your results.
