openCluster: Open a Parallel Cluster

Description

Opens a parallel cluster for computation, registers it for parallel operations, and ensures its closure on script exit.

Usage

openCluster(cluster.type = "SOCK", np = 2, progBar = TRUE, debugging = FALSE)

Value

An object representing the parallel cluster.

Arguments

cluster.type

A character string specifying the type of cluster. Accepted values are "SOCK", "FORK", or "MPI".

np

An integer specifying the number of processes to be used in the parallel cluster.

progBar

logical. If TRUE a progress bar is shown.

debugging

logical. For developer use.

Examples

if (FALSE) {
  # Open a SOCK cluster with 4 cores
  cls <- openCluster("SOCK", 4)
  # Your parallel computation code here
  # The cluster will automatically close when the script exits
}
