Dear list,
i have some problems using the snow package to create a SOCK cluster.
The errors just occour irregularly but it seems to me that they occour
when I try to create more than one cluster on the same machine via
different R instances started via submitting LSF jobs to a cluster. Does
anyone have an idea how to solve this or where to start digging for
solutions?
The error messages are:
library(snow)
cl <- makeCluster(8, type = "SOCK")
Error in socketConnection(port = port, server = TRUE, blocking = TRUE, :
cannot open the connection
Calls: run.call ... makeCluster -> makeSOCKcluster -> newSOCKnode ->
socketConnection
In addition: Warning message:
In socketConnection(port = port, server = TRUE, blocking = TRUE, :
port 10187 cannot be opened
R version 2.15.1 (2012-06-22)
Platform: x86_64-unknown-linux-gnu (64-bit)
