I have to add that we told Jakub to first have a proof of concept of the integration of HPX. And he should not focus too much on optimization in the first phase. I assume we have to play around with execution policy and chunk size as for BLAZE to get better performance. First, HPX was much slower as openmp with default settings and after adjusting it was comparable to openmp.
