^(60)Co集装箱CT系统图像重建的MPI并行实现

Parallel computing for ^(60)Co container CT image reconstruction with MPI

利用M P I并行编程环境,对原有重建CT图像顺序流程并行化,实现了并行计算流程。在4个计算节点的情况下,使重建图像耗时由34s缩短到9s,基本实现了线性加速,获得了很好的重建速度。

Under the MPI parallel programming environment, this paper realized the parallel computing progress through changing the ordinal reconstruction process. The time of reconstruction had reduced from 34 seconds to 9 seconds with four computing nodes which make out an almost linear acceleration.
