Parallel Computing in R

Показать описание
I introduce the concept of parallel computing and demonstrate it using the doParallel and foreach packages.
I run some code and show how parallel computing can speed it up.
I also explain why more cores may not always be faster.

Thanks so much Matt for this amazing video. You changed my point of view when it comes to parallel computing. I thought it was only possible running some instances of R at the same time, but you showed it was not necessary to do so in order to reduce the running time of a model.
The exercise I want to do now is to find out the running time to run 10000 iterations with as many instances as the number of cores of the model and compare it with the time required with a single instance with doParallel cluster.

Thanks for the video! It's interesting to see that three cores performed quite similarly to seven cores.

Could u do a video for beginners in R?
