Abstract

The appearance of multi/many-core processors created a gap between the parallel hardware and sequential software. Furthermore, this gap keeps increasing, since the community cannot find an appealing solution for parallelizing applications. We propose Tareador as a mean for fighting this problem. Tareador is a tool that helps a programmer explore various parallelization strategies and find the one that exposes the highest potential parallelism. Tareador dynamically instruments a sequential application, automatically detects data-dependencies between sections of execution, and evaluates the potential parallelism of different parallelization strategies. Furthermore, Tareador includes the automatic search mechanism that explores parallelization strategies and leads to the optimal one. Finally, we blueprint how Tareador could be used together with the parallel programming model and the parallelization workflow in order to facilitate parallelization of applications.
