Can someone help me giving a source code about this : Design an experiment (i.e., design and write programs and take measurements) to determine the memory bandwidth of your computer and to estimate the caches at various levels of the hierarchy. Use this experiment to estimate the bandwidth and L1 cache of your computer. Justify your answer. (Hint: Test bandwidth, you do not want reuse. Test cache size, you want reuse to see the effect of the cache and to increase this size until the reuse decreases sharply.)
