Abstract

In this paper, we present an adaptive dynamic parallelization scheme which integrates the inspector/executor scheme and the speculation scheme to enhance the capability of a parallelizing compiler and reduce the overhead of dynamic parallelization. Under our scheme, a parallelizing compiler can adaptively apply the inspector/executor scheme or the speculation scheme to a candidate loop that cannot be parallelized statically. We also introduce several techniques which enable dynamic parallelization of certain programs, including SPICE, TRACK and DYFESM in the Perfect Benchmark suite. The experimental results show that our adaptive scheme and techniques are quite effective.
