I faced this problem in round 1 and am still facing it in round 2. It is taking more than a few days to simply make clusters in R. There is nothing heavy loaded till this point, so I doubt it is a memory issue. ``` nCores = min(16,detectCores() - 1) cl<-makeCluster(nCores,outfile = "runningCh1.txt", type="FORK") registerDoParallel(cl) ``` For moderators: submission ID: 9646096 This is very weird because I have used this code many times before and it always worked. Any one successfully ran in parallel in R for this challenge? How did you do it? Is this related to "submissions not processed" thread? Thanks

Thanks. Could you please elaborate on your answer. What exact changes needs to done to the following code: ``` nCores = min(16,detectCores() - 1) cl<-makeCluster(nCores,outfile = "runningCh1.txt", type="FORK") registerDoParallel(cl) ```
you need to use & to parellize.
It is hanging on "makeCluster" indefinitely. After searching this could be a networking or firewall issue. Is there a way to check what the issue is? Why can't it simply create clusters?
