Abstract: A multithreaded layered-code processing method includes: passing through the layered code to discover each layer of the layered code, acquiring a lock when a layer is discovered, determining whether to spawn a thread to process the discovered layer, and, if it is so determined, spawning a thread to process the discovered layer. The method may further include: releasing the lock once the new thread is either spawned or aborted, and, if spawned, proceeding with execution of the thread concurrently with other threads. Other embodiments include a processor for carrying out the method and a computer-readable medium having stored thereon instructions to cause a computer to execute the method.
