Eliminating Syncrhonization Overhead in Automatically Prallelized Programs Using Dynamic Feedback

摘要

This article presents dynamic feedback, a technique that enables computations to adapt dynamically to different execution environments. A compiler that uses dynamic feedback produces several different versions of the same source code; each version uses a different optimization policy. The generated code alternately performs sampling phases and production phases. Each sampling phase measures he overhead of each version in the current environ- ment.
