Abstract

ynamic optimization presents opportunities for finding run-time bottlenecks and deploying optimizations in statically compiled programs. In this paper, we discuss our current implementation of our hardware sampling based dynamic optimization framework and applying our dynamic optimization system to various SPEC2000 benchmarks compiled with the ORC compiler at optimization level O2 and executed on an Itanium-2 machine. We use our optimization system to apply memory prefetching optimizations, improving the performance of multiple benchmark programs.
