Implementing heap-object behavior prediction dfficiently and dffectively

摘要

Heap-allocated objects play an important role in many modern programs. Various results have shown the overall performance of these programs can be improved by increasing the reference locality of heap- allocated objects. In this paper we describe an approach that improves the virtual memory performance of allocation-intensive C programs by predicting the reference behavior and lifetime of heap objects as they are allocated. We further describe an implementation of our prediction algorithm and evaluate its performance on real programs.
