• On the performance and energy efficiency of the PGAS programming model on multicore architectures 

      Lagraviere, Jeremie Alexandre Emilien; Langguth, Johannes; Sourouri, Mohammed; Ha, Hoai Phuong; Cai, Xing (Chapter; Conference object; Peer reviewed, 2016)
      Using large-scale multicore systems to get the maximum performance and energy efficiency with manageable programmability is a major challenge. The partitioned global address space (PGAS) programming model enhances ...
    • The READEX formalism for automatic tuning for energy efficiency 

      Schuchart, Joseph; Gerndt, Michael; Kjeldsberg, Per Gunnar; Lysaght, Michael; Horák, David; Říha, Lubomír; Gocht, Andreas; Sourouri, Mohammed; Kumaraswamy, Madhura; Chowdhury, Anamika; Jahre, Magnus; Diethelm, Kai; Bouizi, Othman; Mian, Umbreen Sabir; Kružík, Jakub; Sojka, Radim; Beseda, Martin; Kannan, Venkatesh; Bendifallah, Zakaria; Hackenberg, Daniel; Nagel, Wolfgang E. (Journal article; Peer reviewed, 2017)
      Energy efficiency is an important aspect of future exascale systems, mainly due to rising energy cost. Although High performance computing (HPC) applications are compute centric, they still exhibit varying computational ...
    • Towards Fine-Grained Dynamic Tuning of HPC Applications on Modern Multi-Core Architectures 

      Sourouri, Mohammed; Raknes, Espen Birger; Reissmann, Nico; Langguth, Johannes; Hackenberg, Daniel; Schöne, Robert; Kjeldsberg, Per Gunnar (Chapter, 2017)
      There is a consensus that exascale systems should operate within a power envelope of 20MW. Consequently, energy conservation is still considered as the most crucial constraint if such systems are to be realized. So far, ...
