自动使用多个内核的R包? [英] R package that automatically uses several cores?

问题描述

我注意到R在执行需要大量计算的程序之一时仅使用一个内核.我想利用我的多核处理器来使程序运行更快. 我尚未对此问题进行深入调查，但是希望您能从您的评论中受益，因为我对计算机科学缺乏了解，而且我很难获得有关该主题的容易理解的信息.

I have noticed that R only uses one core while executing one of my programs which requires lots of calculations. I would like to take advantage of my multi-core processor to make my program run faster. I have not yet investigated the question in depth but I would appreciate to benefit from your comments because I do not have good knowledge in computer science and it is difficult for me to get easily understandable information on that subject.

是否有允许R在需要时自动使用多个内核的软件包?

Is there a package that allows R to automatically use several cores when needed?

我想这不是那么简单.

推荐答案

R只能在附加软件包的帮助下使用多个内核，并且只能用于某些类型的操作.有关这些选项的详细信息，请参见CRAN上的高性能计算任务视图

R can only make use of multiple cores with the help of add-on packages, and only for some types of operation. The options are discussed in detail on the High Performance Computing Task View on CRAN

更新:由于R附带的 parallel 软件包作为推荐软件包，因此不一定需要R版本2.14.0中的附加软件包. parallel 包括多核和 snow 程序包中的功能，

Update: From R Version 2.14.0 add-on packages are not necessarily required due to the inclusion of the parallel package as a recommended package shipped with R. parallel includes functionality from the multicore and snow packages, largely unchanged.
