In the previous API methods, only the wait() and end() methods are blocking operations that can block the main application indefinitely. Therefore, if you declare multiple graphs at the top level, you need to interleave the APIs suitably to execute the graphs in parallel, as shown.

#include "project.h"
simpleGraph g1, g2, g3;

int main(void) {
  g1.init(); g2.init(); g3.init();<num-iter>);<num-iter>);<num-iter>);
  g1.end(); g2.end(); g3.end();
  return 0;
Note: Each graph should be started (run) only after it has been initialized (init). Also, to get parallel execution, all the graphs must be started (run) before any graph is waited upon for termination (end).
