Performance Evalution Of Multi - Core Systems Using SPEC CPU 2006 And SPEC Power - SSJ 2008 Benchmarks

Abstract

Multi-core processor architectures are designed to boost performance and minimize heat output by integrating two or more processor cores into a single processor socket. The blade servers are multi-core systems with the increasing number of available multi-core processor architectures. This thesis presents performance studies of industrial benchmarks on a multi-core system that are designed to compare total performance. The selected benchmarks are SPEC CPU2006 and SPECpower_ssj2008. To evaluate the performance, power consumption and performance-to-watt ratio, the benchmarks results are monitored and compared of several blade servers with firstly, same multi-core processor series, secondly, with increasing number of cores of the same multicore processor series and thirdly, with different multi-core processor series. The thesis observes that these benchmarks scale close to be linearly with increasing number of cores. These results can be used by performance engineers and developers to better understand the benchmarks workload and select input dataset for better micro architecture design of the multi-core systems.
