Abstract:

Dynamic optimization is one of the most important techniques for computing system virtualization. Based on the analysis of some existing dynamic optimization systems, such as DynamoRIO and Jrpm, this paper concludes the problems and challenges of traditional dynamic optimization mechanisms on multicore platforms first. Then, it proposes a dynamic optimization framework for multithreads based on multicore platforms, analyzes its structure and working principles, and proves its feasibility by experiments.

Key words: multithreads;multicore;dynamic optimization
