Charm++ parallel programming system

Hi,

I've been able to use tracemode projections successfully with my code. I get the results over all the time steps in my code, but as a next step I wanted to gather traces around selective time steps. I've naively placed calls to traceBegin() and traceEnd() inside an SDAG portion of my code, but I get the following compiler error:

STDIN:73:25-34: error: unknown SDAG construct or malformed entry method declaration.
You may have forgotten to terminate a previous entry method declaration with a semicolon or forgotten to mark a block of sequential SDAG code as 'serial'
  if(outer_iter==0) traceBegin();

The pseudo code of what I'm trying to do here is below. This is the body of code in my main ci file:

    entry void move_all_distributed() {

     for(outer_iter = 0; outer_iter < maxiterations; outer_iter++) {

        serial "init_start_outer_loop" {

        //----Call some entry methods---------

        //----Set start and end of selective tracing----------------------//
        if(outer_iter==0) traceBegin();
        if(outer_iter==10) traceEnd();

        //-----Call some more entry methods--------

 

        }

    }

I'd be grateful if you could help me with the right way to call traceBegin and traceEnd.

Thanks,

Hemanth.
