title: initializing akka actor systems with same name
body: <p>I am new to akka actor system. I am a bit confused about how a actor system is named. if I write</p>
  
  <pre><code>ActorSystem _system1 = ActorSystem.create("multi");
  ActorSystem _system2 = ActorSystem.create("multi");
  ActorSystem _system3 = ActorSystem.create("multi");
  </code></pre>
  
  <p>what is gonna happen in the background? Will there be 3 different instances of the actor system in the JVM? if yes, then how do I access the actors belonging to these actor systems over remoting?</p>
