  • Concurrent garbage collection with minimal graph traversal
    Patent number: 11221947
    Abstract: Systems and techniques for garbage collection are disclosed for concurrently performing a garbage collection cycle in a single traversal of a garbage collection heap while application threads are running. The garbage collection cycle includes marking a first memory object as live. The garbage collection cycle also includes determining that a forwarding pointer of the first memory object points to the first memory object. The garbage collection cycle further includes evacuating the first memory object to a free region based on the determining. The garbage collection cycle additionally includes evacuating a second memory object in the same single traversal of the garbage collection heap in which the first memory object is being marked live.
