ABSTRACT:
One embodiment of the present invention provides a system that facilitates keeping track of memory usage of tasks in a shared heap without performing a full garbage-collection operation. The system operates by determining a memory usage by each task in a young generation of the shared heap. Once the memory usage for each task has been determined, the system then adds the memory usage for each task in the young generation of the shared heap to a global memory usage for each task (obtained during a preceding full garbage-collection operation) to produce an actual memory usage for each task.
