Abstract
Methods and systems for performing garbage collection include issuing a memory fence that indicates that a number of tasks in a garbage collection deque, belonging to a first garbage collection thread, has decreased by more than one. A length of the garbage collection deque, after the memory fence is issued, is determined to be greater than zero. Multiple tasks are popped from the garbage collection deque responsive to the determination that the length of the garbage collection deque is greater than zero. Garbage collection is performed on the popped tasks.
