Charm++ parallel programming system

[Christian Perez <christian.perez AT inria.fr>]

Hello,

I'd like to know how to block a thread. Here is a simple version of what 
I'd like to do:

Chare A:
  m1() {
    do some computation
    invoke method m2 on chare B
    wait for the completion of method m2
    do something else
  }

I've tried to use some callback mechanism but the problem is that
I can not split m1 in two :(

So, is there a wait to suspend the execution (and also how to resume it) ?

Thank you!
