摘要
En 中文
Multi-core architectures have emerged as the dominant architecture for both desktop and high-performance systems. Multi-core systems introduce many challenges that need to be addressed to achieve the best performance. Therefore, benchmarking of these processors is necessary to identify the possible performance issues. In this paper, broad range of homogeneous multi-core architectures are investigated in terms of essential performance metrics. To measure performance. we used micro-benchmarks from High-Performance Computing Challenge (HPCC), NAS Parallel Benchmarks (NPB), LMbench, and an FFT benchmark. Performance analysis is conducted on multi-core systems from UltraSPARC and x86 architectures; including systems based on Conroe, Kentsfield, Clovertown, Santa Rosa, Barcelona, Niagara, and Victoria Falls processors. Also, the effect of multi-core architectures in cluster performance is examined using a Clovertown based cluster. Finally, cache coherence overhead is analyzed using a full-system Simulator. Experimental analysis and observations in this study provide for a better understanding of the emerging homogeneous multi-core systems. (C) 2009 Elsevier B.V. All rights reserved.
