small question about cluster. SCHED_RR

[p3x-robot]

ciao, could tell me what the round robin cluster scheduling?
if a process uses cpu 100% load in a fork worker, does it count about it or is something completely scheduling? so it will use another process when it overloaded?

From the docs:

The first one (and the default one on all platforms except Windows), is the round-robin approach, where the master process listens on a port, accepts new connections and distributes them across the workers in a round-robin fashion, with some built-in smarts to avoid overloading a worker process.

Does that answer your question?

I'm not sure there's much C++ for cluster, it's mostly js in lib/internal/cluster.
