ABSTRACT:
The invention relates to a method for performing generational garbage collection on a heap comprising a plurality of generations. The method involves dividing a young generation of the heap into a first young generation and a second young generation, evacuating the first young generation concurrently with allocating the second young generation, and evacuating the second young generation concurrently with allocating the first young generation and subsequent to fully evacuating the first young generation.
