如何在 Octave 或 Scilab 中使用并行“for"循环? [英] How to use parallel 'for' loop in Octave or Scilab?

问题描述

我在我的 Matlab 代码中运行了两个 for 循环.内部循环在 12 个处理器中使用 Matlabpool 并行化(这是 Matlab 在单台机器中允许的最大值).

I have two for loops running in my Matlab code. The inner loop is parallelized using Matlabpool in 12 processors (which is maximum Matlab allows in a single machine).

我没有分布式计算许可证.请帮助我如何使用 Octave 或 Scilab 做到这一点.我只想并行化for"循环.

I dont have Distributed computing license. Please help me how to do it using Octave or Scilab. I just want to parallelize 'for' loop ONLY.

我在谷歌搜索时给出了一些损坏的链接.

推荐答案

parfor 还没有真正在八度音阶中实现.关键字被接受，但只是 for 的同义词 (http://Octave.1599824.n4.nabble.com/Parfor-td4630575.html).

parfor is not really implemented in octave yet. The keyword is accepted, but is a mere synonym of for (http://octave.1599824.n4.nabble.com/Parfor-td4630575.html).

并行包的pararrayfun 和parcellfun 函数在多核机器上很方便.它们通常可以很好地替代 parfor 循环.

The pararrayfun and parcellfun functions of the parallel package are handy on multicore machines. They are often a good replacement to a parfor loop.

示例见http://wiki.octave.org/Parallel_package.要安装，请发出(仅一次)

For examples, see http://wiki.octave.org/Parallel_package. To install, issue (just once)

pkg install -forge parallel

然后，每个会话一次

pkg load parallel
