A slotted read-write lock is a lock data structure associated with a shared memory area, wherein the slotted read-write lock indicates whether any thread has a read-lock and/or a write-lock for the shared memory area. Multiple threads may concurrently have the read-lock but only one thread can have the write-lock at any given time. The slotted read-write lock comprises multiple slots, each associated with a single thread. To acquire the slotted read-write lock for reading, a thread assigned to a slot performs a store operation to the slot and then attempts to determine that no other thread holds the slotted read-write lock for writing. To acquire the slotted read-write lock for writing, a thread assigned to a slot sets its write-bit and then attempts to determine that the write-lock is not held."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Concurrency control using slotted read-write locks","description":"A system and method for concurrency control may use slotted read-write locks.
