Worker-checker - A framework for run-time parallelization on multiprocessors

Run-time parallelization is a technique for solving problems whose data access patterns are diicult to analyze at compile time. In this paper we propose a worker-checker framework to classify existing run-time parallelization schemes. From the framework, several new approaches to run-time parallelization can be identiied. The implementation of one such scheme, called the overlapped worker-then-checker, is then examined and its performance is studied. Performance results show that the new scheme outperforms previous approaches.
