In this paper, the authors find the relationships between the memory system and performance in both single core and multicore context. For the single core part, several parameters have been considered to improve the performance. Based on these paper they extend to the multi-core issues. Overall, the simulations showed results similar to configurations of many current consumer CMPs. Many results were expected, like a large L2 cache size certainly helped performance a lot and the L1 cache size, optimal system frequency was typical of many of the Intel Core 2 Duos, and that after already having 2-4 core any more cores do not help performance in FFT nearly as greatly.
