How to run randomForest in R on multiple cores in parallel? [duplicate]

Question

I have a randomForest model that I want to calculate on multiple cores. How can I tell the model to run in parallel?

This is not a duplicate of parallel execution of random forest in R as I don't need to run multiple models in parallel, I want one model to run in parallel.

Answer 1

I use the doMC package and its registerDoMC function. Works really well.
