HPX Smart Executors

no code implementations5 Nov 2017 Zahra Khatami, Lukas Troska, Hartmut Kaiser, J. Ramanujam, Adrian Serio

Moreover, we advocate a novel method by introducing HPX smart executors for determining the execution policy, chunk size, and prefetching distance of an HPX loop to achieve higher possible performance by feeding static information captured during compilation and runtime-based dynamic information to our learning model.
