Identifiers are assigned to each thread. Flags in conjunction with the thread identifiers are used to determine the continuity of the lock with a thread. However, in the event continuity of the lock with the thread ceases, a compare-and-swap operation is executed to reset the lock with the same thread or another thread. Similarly, in the event there has been a collision between two or more threads requesting the lock, a compare-and-swap operation is executed to assign the lock to one of the requesting threads. Accordingly, prolonged ownership of a lock operation by a thread is encouraged to mitigate use of atomic operations in granting of the lock to a non-owning thread."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for speeding up mutual exclusion","description":"In a multiprocessor computer system, a lock operation is maintained with a thread using non-atomic instructions.
