Charm++ parallel programming system

[Jonathan Lifflander <jliffl2 AT illinois.edu>]

Hey,

When you are using parameter marshalling (I'm assuming that "Input" is
not a message), the first parameter you send becomes the reference
number that is matched to "iter".

So you should add an integer as the first parameter, like this:

entry void runForever() {
  for (iter = 0; iter < nIters; ++iter) {
    // Match to only accept inputs for the current iteration
    when iterationWork[iter](int ref, Input in) {
      // Do something
    }
  }
};

When you send a to this, you can send the reference number that you
want to match. For instance, if you want a reference number of 10, you
could make the following call:

proxy. iterationWork(10, Input(...));

I'm attaching some slides used in a class that was taught at UIUC,
which include examples of how to use reference numbers and more
explanation.
