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, 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 ... -
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, ...
