fps help

I am running 'psubmit' demo program on one machine. i a try to measure
fps like this:

int main(){

...
for (frame = 0; ; frame++)
        {
                if (opt.clearFlag)
                        glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
                glBarrierExecCR_ptr( MASTER_BARRIER );
                glPushMatrix();
                
                drawMyScene(frame, opt.rank);
                
                glPopMatrix();
                glBarrierExecCR_ptr( MASTER_BARRIER );
                if (opt.swapFlag) {
                        // really swap 
                        crSwapBuffers_ptr( window, 0 );
                }
                else {
                        // don't really swap, just mark end of frame 
                        crSwapBuffers_ptr( window, CR_SUPPRESS_SWAP_BIT );
                }

                getFPS();
        }
...
}
