In the previous lesson, we went over an application example of using MPI_Scatter and MPI_Gather to perform parallel rank computation with MPI. We are going to expand on collective communication routines even more in this lesson by going over MPI_Reduce and MPI_Allreduce.Note - All of the ...
其中需要注意,定时器中的代码是在子线程中运行的,而滚动图片操作和更新页签操作都是UI操作,因此需要放到Handler中去执行。...接下来才是今天的重点,我们要使用自定义属性来启用自动播放功能,这样才能让你更加接近高手,才能让你更加玩转Android。...在最外层的LinearLayout加入在我们自定义的com.example.viewswitcher....

この例では、関数 spmdReduce およびそれを利用する関数 spmdPlus および spmdCat について確認します。
在Linux下,如果有其它应用需要一致性备份,可以编写自己的冻结、解冻脚本,来实现应用的保护。自定义脚本需放置在/home/rdadmin/Agent/bin/thirdparty/ebk_user目录中,供Agent在备份过程中调用。下面以一个虚构的应用appexample为例,来进行说明。appexample是一款新的数据库,它对外提 ...
The reduction functions (MPI_Op) do not return an error value. As a result, if the functions detect an error, all they can do is either callMPI_Abortor silently skip the problem. Thus, if you change the error handler fromMPI_ERRORS_ARE_FATALto something else, for example,MPI_ERRORS_RE...
