Performance study of Core2Duo desktop processors

The multicore processors turned out to open the doors to make the desktop to have parallel and high performance capability. In this paper, the performance study for these systems is presented, in which the studies were carried out on the Intel´s Core2Duo processor with an OpenMP programming integrated into Microsoft visual studio C++ 2005 and Intel C++ 10.1.020 compiler. Using multithreaded programming, this paper provides the performance measurement for dual core over a single core and assessing the performance of the OpenMP multithreaded programming on a Core2Duo processor. The speedup of dual-core over a single core and the behaviour of Core2Duo processor with OpenMP programming are reported. Our results reveal that the Core2Duo performance with OpenMP multithreaded programming falls behind the Core2Duo performance in a sequential mode when the workload exceeds the size of the L2 cache, also the dual core speedup drops drastically to about 1.1. Finally we measured the performance using the Stream and Stream2 benchmarks and analyse the running results.
