Run multiple R-scripts simultaneously

Question

In my thesis I need to perform a lot of simulation studies, which all takes quite a while. My computer has 4 cores, so I have been wondering if it is possible to run for exa

Answer 1

You can achieve multicore parallelism (as explained here https://cran.r-project.org/web/packages/doMC/vignettes/gettingstartedMC.pdf) in the same session with the following code

if(Sys.info()["sysname"]=="Windows"){
  library(doParallel)
  cl<-makeCluster(numberOfCores)
  registerDoParallel(cl)
}else{
  library(doMC)
  registerDoMC(numberOfCores)
}
library(foreach)

someList<-list("file1","file2")
returnComputation <-
  foreach(x=someList) %dopar%{
    source(x)
  }


if(Sys.info()["sysname"]=="Windows") stopCluster(cl)

You will need still adapt your output.
