i was asking myself if and how rstudio or r uses multiple cores of my cpu. researching brings up mostly topics from around ~2010,which suggest using parallel or other packages to achieve multicore usage.
If i monitor my cpu usage while running intense scripts (e.g. monte carlo simulations with "vectorized" drawing "processes" looping through different distributions) , all cores seem to be busy and increase in their usage.
so this implies multicore usage to a certain extend, my question is if this just looks like it and the process runs only on one core. I got an i7 7760U.
thanks in advance and best regards,
