Optimization strategies of data processing algorithms under multi- core architecture. Journal of Frontiers of Computer Science and Technology, 2011, 5(12): 1057-1075. Abstract: Multi-core processors, especially the single chip multi-processors (CMP), can provide strong parallel resources of sharing memory. However, the majority of programs and algorithms from single-core processors can not make full use of computing resources of multi-core architecture. Therefore, according to some characteristics of multi-core architecture, researchers should optimize those algorithms and substantially increase the performance of algorithms. This paper reviews related optimization strategies of data processing algorithms on multi-core processors around several aspects, including improving the locality of programs, decreasing cache access conflic
