Charm++ parallel programming system

[Haowei Huang <huangh AT in.tum.de>]

Hi phil,

     I want to create a point-to-point communication between two chares each of which is an element of a chare array. For example,
     chare A {
         ....
         void requestMsg{
              messageToB = local information;
              arrayB[i].getValue(Msg1*messageToB);
         }
         
         void comsumingMsg(Msg2*msgFromB){
           
             //dealing with msgFromB;
       
         }
     }

     chare B {
           
          void getValue(Msg1*message){

                arrayA[j].comsumingMsg(Msg2*messageToA);

         }
    }

     However, I always get such runtime error "Reason: Message being re-sent. Aborting... "  Do you have any idea about it? As far as I know ,this is one of four ways to create point-to-point with return value. How does Charm++ guarantee this communication happens atomically except for using [sync] entry methods? Thank you so much.
