<p><b>Abstract</b>—In the paper "Static Rate-Optimal Scheduling of Iterative Data-Flow Programs via Optimum Unfolding", the authors stated a perfect-rate property on unfolded data-flow graphs (DFGs). This will be disproven in the following by a simple counter example.</p>
Data-flow graphs, data-flow programs, perfect-rate.
