| Abstract: | MrBayes is a phylogenetic analysis program,which now is extensively used in phylogenetics.Considering the high parallelism of GPU(graphic process units),Jianfu Zhou and others from Nankai University put forward a changed CPU-GPU collaborative algorithm of MrBayes,and have achieved wonderful result.In this thesis,we put forward an optimization algorithm of MrBayes on the basis of CPU-GPU collaborative algorithm above.By changing the algorithm and reorganizing the order of calculation,we improved speedup ratio and achieved better performance indeed. |
