I correct:

Using one global lockfree queue, it gave a negative scalability of  -2.7x

Using mutiple lockfree local queues with work-stealing
and using the execute() method , it gave 2.5x scalability

And using multiple lockfree local queues with work-stealing
and using my new Exec() method , it can go up to 3.8x scalability.
