doSNOW can show progressbar like below

How to show the progress of code in parallel computation in R?

is there a way to get progressbar in doParallel?

Update:

below is a minimal reproducible example

library(foreach)

library(doParallel)

mc <- detectCores()

cl <- makeCluster(mc)

registerDoParallel(cl)

result <- foreach(i = 1:100) %dopar% {
  rnorm(1000000) %>% sd
}

stopCluster(cl)

  • You could make a nice question out of it if you'd provide a [mcve]. – jay.sf Sep 18 '19 at 18:18
  • Historically it has been shown that because `doParallel` does its "combine" all at the end, it is unlikely to be able to get good progress. https://stackoverflow.com/a/10982524. It is possible that things have changed since that answer, I'm not aware. – r2evans Sep 18 '19 at 18:29
