10 LAOHU & HPC-GRID PORTAL(Gridway, Dirac) GLOBUS Toolkits Internet

11 AstroGrid-D

12 LAOHU in the future 1. Upgrade the GPU Cards to K20 2. Add a Intel phi 5110 Card other requirement.

13 Correlator 1. 射电望远镜 2. 综合孔径成像

14 相关器理论基础

15 数据相关处理流程

16 并行化处理 ( 一 ) Openmpi 调度所有的进程,使得各进程能够 根据 RANK 来执行不同的操作 采用双缓冲机制来实现采集与发送的并 行,MPI 接收与执行的并行

17 采用 OPENMP 来增加进程内部的并行性, 使得单进程在不同的处理阶段形成多线 程的流水线结构。同时,通过 OPENMP 也 可以优化循环代码,使得循环操作也能 够尽可能的实现并行。 并行化处理 ( 二 )
