In your paper, the experiments compare the generated code against code hand-written against the same API. Those experiments demonstrate that your optimizing compiler generates code that matches what experts can write - a very good and necessary comparison.<p>But I&#x27;m also curious about the parallelization costs, and other costs incurred by the programming model. The best way to explore those costs are to compare against an optimized sequential version that solves the same problem. Do you have any experiments which do that?
