Can a person put mclapply in a foreach loop? Based on this post here <http://stackoverflow.com/questions/34704733/parallel-r-with-foreach-and-mclapply-at-the-same-time>, I wrote a script, seen here:
"library(parallel) library(doParallel) cl<-makeCluster(2,outfile='') registerDoParallel(cl) foreach(i=1:5, .packages='parallel') %dopar% { system.time(mclapply(1:10, function(x){rnorm(1e5)},mc.cores=2))} stopCluster(cl)" It worked initially but is now throwing up error codes: "Error in unserialize(node$con) : error reading from connection Calls: <Anonymous> ... doTryCatch -> recvData -> recvData.SOCKnode -> unserialize Execution halted Error in unserialize(socklist[[n]]) : error reading from connection Error in unserialize(node$con) : error reading from connection Calls: <Anonymous> ... doTryCatch -> recvData -> recvData.SOCKnode -> unserialize Execution halted" Any idea what's going on? This is on a single machine, not a cluster.
