Each gen_server is, indeed, a single process. What you can do, however, is spawn multiple gen_servers under a single supervisor. You can do this by creating a <b>one_for_one</b> or <b>one_for_all</b> supervisor with multiple child specifications, or a <b>simple_one_for_one</b> supervisor and then make multiple calls to <b>supervisor:start_child(Supervisor_name, Args)</b>.<div><br></div><div>Either of these methods will give you multiple gen_server processes under a supervision tree, it just depends on exactly what you want to do.
