Multithreading on Multiprocessor

I am trying to run a multithreaded program on an SGI Origin 2000 running IRIX 6.5. The program does not appear to be utilizing multiple processors. Other programs show parallel execution, so it appesars that I have the system configured properly. Here is the code that starts the threads:
/**
*/
public void initiate() {
Iterator procs = processor_map.values().iterator();
LocalOptProcessor curr_proc = null;
int i = 0;
while ( procs.hasNext() ) {
curr_proc = (LocalOptProcessor)procs.next();
Thread th = new Thread(curr_proc, "Proc"+i);
th.start();
threads[i] = th;
i++;
}
}
If anyone can offer any suggetions as to why this does not work, I would greatly appreciate it. Thanks.
...Mike

Please tell first what's "processor_map" and "LocalOptProcessor ". How do you implement them??
