Abstract
Apparatus, methods, systems and computer program products are disclosed describing processes that optimize generational garbage collection techniques in a card-marked heap. The invention localizes nodes in an older generation that have a pointer to a newer generation. This node localization increases the density of such nodes in the cards marked as having these nodes and thus reduces the number of marked cards that need to be examined for nodes having pointers to the newer generation.
