Execute IgniteRunnable in all Ignite nodes?

[Lokesh Sharma]

During some events I want to run a piece of code at all nodes of Ignite. Is
it possible? I know, its possible to run a Runnable in exactly any one of
the nodes using

  exec.submit(new IgniteRunnable() {
    @Override public void run() {
      System.out.println(">>> Printing '" + word + "' on this node
from grid job.");
    }
  });


So, I was wondering if there's something like "exec.runAll" that would run
the IgniteRunnable in all instances?
