PAT: a postmortem object access pattern analysis and visualization tool

Applying a cache coherence protocol capable of adapting to memory access patterns is a viable approach to improving the performance of software distributed shared memory. In this paper, we present an approach of postmortem memory access pattern analysis and visualization, which has been applied to our design of a global object space for a distributed Java Virtual Machine. The tool not only can enhance our understanding of the access patterns inherent in an application but can also help us to evaluate the effectiveness of an adaptive protocol used in the design of the global object space.
