Default cluster

Setting up a cluster is relatively expensive, so it's best to use a single cluster throughout a session. This function lazily creates a 2-worker cluster for use in examples and test.

Usage

default_cluster(n = 2)

Arguments

n

Number of workers to use; defaults to 2 because this is the maximum allowed by CRAN.

Value

A cached cluster of workers.

Examples

default_cluster()
#> 2 session cluster [..]
