In the context of programming, particularly with the Node.js cluster module, "cluster fork" refers to the action of creating a new child process (worker) from a master process. This new process, or "worker", runs a separate instance of the application code, potentially on a different CPU core, allowing for improved performance and scalability. Link
The cluster fork is a programming language. I initially thought there is a tool called cluster fork but I think the meaning as a programming language is better.
