How to make "R" use all CPUs

  • 772

I am using GNU R to calculate a huge dataset. My PC has 4 CPU-cores, and I can see, that R is using only 1 CPU.

Is there a way to tell R to use all 4 CPUs in order to make the calculation complete faster?

    You should use the r-cran-multicore package to enable multiple cpu processing:

    sudo apt-get install r-cran-multicore

    See details about this functionality here: http://www.rforge.net/multicore but as a warning, your 'R' code will probably have to be updated to take advantage of multiple core technology. unless you are already using pre-made code which supports the multicore extensions.
