Abstract
A method and system of carrying out garbage collection in a computer system. Specifically, the method and system utilize low contention grey object sets for concurrent marking garbage collection. A garbage collector traces memory objects and identifies memory objects according to a three-color abstraction, identifying a memory object with a certain color if that memory object itself has been encountered by the garbage collector, but some of the objects to which the memory object refers have not yet been encountered. A packet manager organizes memory objects identified with the certain color into packets, provides services to obtain empty or partially full packets, and obtain full or partially full packets, and verifies whether a packet of the certain color is being accessed by one of the threads of the garbage collector.
