Abstract: A memory heap is allocated to a contiguous range of memory. One end of the heap is designated as a small object area. The other end of the heap is designated as a large object area. When the two object areas grow, the small object area grows inward within the heap toward the large object area, and the large object area grows inward within the heap toward the small object area.

Abstract: A method, system and computer program product for reducing garbage collection pause time. According to example embodiments, a garbage collection cycle is initiated on a set of objects that have been dynamically allocated in a memory. An identification is made of new persistent objects and reachable non-persistent objects while ignoring old persistent objects that have been identified as persistent in previous garbage collection cycles. The new persistent objects are associated as members of a set of persistent objects that includes the old persistent objects. The persistence information for the set of persistent objects is preserved for use during subsequent garbage collection cycles. All reachable non-persistent objects and all persistent objects in the set of persistent objects are marked for memory reclamation phase processing.

Abstract: Managing multiple object areas in a memory heap, comprises allocating a memory heap as a contiguous range of memory, allocating a small object area within the memory heap having an initial start at a first end of the memory heap and allocating a large object area within the memory heap having an initial start at a second end of the memory heap opposite the first end such that the small object area and the large object area grow in opposite directions inward within the memory heap. Further, allocations are performed into the memory heap based upon a predetermined allocation policy such that the large object area is reserved for the allocation of large objects.
