摘要

随着多核处理器的逐渐普及,它将成为未来处理器发展的必然趋势,各种应用都将采用多核架构.在基于差异进化算法的基础上,在图形工作站上充分利用多核处理器的并行计算能力,实现多核并行化差异进化算法,并将其应用于三维医学图像配准,实现快速配准算法.实验数据表明,与传统方法相比,多核并行化方法在保证精度和稳定性的前提下,配准速度提升接近于理想加速比.%With the popularization of multicore CPU,it will be the trend of CPU and be used to different applications.A multicore-based parallelized differential evolution algorithm is proposed,which takes advantage of parallel computing capabilities of multicore CPU on graphic workstation. It accomplishes the parallel evolution algorithm and realizes the multicore-based parallelized fast medical image registration.The experimental results show that,it not only has no differ-ence in precision and stability with traditional image registration based on differential evolution,but also exhibits fast con-vergence and almost has an ideal speedup.
