I am experiencing a problem already raised before here and here, but in a different context. Suppose I have an R script file called psock.R that contains the following code: cat("Setup cluster...

I'm trying to parallelize a code on 4 nodes(type = "SOCK"). Here is my code. library(itertools) library(foreach) library(doParallel) library(parallel) workers <- ip address of 4 nodes cl = mak...

I am loading the following packages into R: library(foreach) library(doParallel) library(iterators) I "parallelize" code for a long time, but lately I am getting INTERMITTENT stops while code is...

I've written a function in Rcpp and compiled it with inline. Now, I want to run it in parallel on different cores, but I'm getting a strange error. Here's a minimal example, where the function funC...

I'm using the doSNOW package and more specifically the parLapply function to perform reclassification (and subsequently other operations) on a list of big raster datasets (OS: Windows x64). The co...

I use the following code to ... 1. create a parallel cluster 2. source test.R 3. and do some parallel work with functions defined in 'test.R' library(parallel) cl <- makeCluster(4) clusterEvalQ...

The following (simplified) script works fine on the master node of a unix cluster (4 virtual cores). library(foreach) library(doParallel) nc = detectCores() cl = makeCluster(nc) registerDoParalle...

I'm using the snow package in R to execute a function on a SOCK cluster with multiple machines(3) running on Linux OS. I tried to run the code with both parLapply and clusterApply. In case of any...

I need to run thousands* of models on 15 machines (each of 4 cores), all Windows. I started to learn parallel, snow and snowfall packages and read a bunch of intro's, but they mainly focus on the s...

The makeCluster function for the SNOW package has the different cluster types of "SOCK", "PVM", "MPI", and "NWS" but I'm not very clear on the differences among them, and more specifically which wo...

I am using makeCluster function from R package snow from Linux machine to start a SOCK cluster on a remote Linux machine. All seems settled for the two machines to communicate succesfully (I am abl...

I've got two servers on a LAN with fresh installs of Centos 6.4 minimal and R 3.0.1. Both computers have doParallel, snow, and snowfall packages installed. The servers can ssh to each other fine. ...

I've got a Windows HPC Server running with some nodes in the backend. I would like to run Parallel R using multiple nodes from the backend. I think Parallel R might be using SNOW on Windows, but no...

How would I register a PSOCK cluster (created using package Parallel) with foreach? I'm currently using registerDoSNOW in the doSNOW package to register a snow SOCK cluster.

I'm attempting to run a parallel job in R using snow. I've been able to run extremely similar jobs with no trouble on older versions of R and snow. R package dependencies prevent me from reverting....
