<!-- source_link=lib/cluster.js -->

A single instance of Node.js runs in a single thread. To take advantage of
multi-core systems, the user will sometimes want to launch a cluster of Node.js
processes to handle the load.
Clusters of Node.js processes can be used to run multiple instances of Node.js
that can distribute workloads among their application threads. When process
isolation is not needed, use the [`worker_threads`][] module instead, which
allows running multiple application threads within a single Node.js instance.

The cluster module allows easy creation of child processes that all share
server ports.
