Understanding Recursive Divide-and-Conquer Dynamic Programs in Fork-Join and Data-Flow Execution Models

On shared-memory multicore machines, classic two-way recursive divide-and-conquer algorithms are implemented using common fork-join based parallel programming paradigms such as Intel Cilk+ or OpenMP. However, in such parallel paradigms, the use of joins for synchronization may lead to artificial dependencies among function calls which are not implied by the underlying DP recurrence. These artifici...
