Charm++ parallel programming system

Hi All,

I have the following issue with the load balancing.

In the code below in myClass2 constructor, if usesAtSync = CmiTrue, the load 
balancer blocks (ResumeFromSync is never called on myClass1). If in myClass2, 
usesAtSync is not set to CmiTrue, myClass1:ResumeFromSync() is called and the 
program successfully exits.

Is there something I am doing wrong? In my code, I have two (and in future 
will have more) arrays, and only one of them I would like to migrate via 
AtSync mode (not periodic).

The source file of complete test program is here 
http://darkstar.astro.northwestern.edu/charm/lbtest.tar.gz

Thanks for help!

Cheers,
 Evghenii



Main::Main()
{
 .... 

  arrayProxy1 = CProxy_myClass1::ckNew(128);
  arrayProxy2 = CProxy_myClass2::ckNew(128);

  thisProxy.doSimulation()  /* this is threaded method */
}

void Main::doSimulation()
{
  arrayProxy1.startLB(CkCallbackResumeThread()));
  CkExit();
}

void myClass1::startLB(CkCallback&cb)
{
   mainCb = cb;  
   AtSync();
}

void myClass1::ResumeFromSync()
{
   contribute(mainCb);
}

myClass1::myClass1()
{
  usesAtSync = CmiTrue;
}

myClass2::myClass2()
{
#if 1
  usesAtSync = CmiTrue;
#endif
}
