SUMMARY:Performance Portability Across Diverse Computer Architectures
DESCRIPTION:Workshop\n\nPerformance Portability Across Diverse Computer Ar
 chitectures\n\nDeakin, McIntosh-Smith, Price, Poenaru, Atkinson...\n\nPrev
 ious studies into performance portability have typically analysed a single
  application (and its various implementations) in isolation. In this study
 , we explore the wider landscape of performance portability by considering
  a number of applications from across the space of dwarfs, written in mult
 iple parallel programming models, and across a diverse set of architecture
 s. We apply rigorous performance portability metrics, as defined by Pennyc
 ook et al [Pennycook2016]. We believe this is the broadest and most rigoro
 us performance portability study to date, representing a far reaching expl
 oration of the state of performance portability that is achievable today. 
 We will present a summary of the performance portability of each applicati
 on and programming model across our diverge range of twelve computer archi
 tectures, including six different server CPUs from five different vendors,
  five different GPUs from two different vendors, and one vector architectu
 re. We will conclude with an analysis of the performance portability of ke
 y programming models in general, across different application spaces as we
 ll across differing architectures, allowing us to comment on more general 
 performance portability principles.\n\nTag: Workshop Reg Pass, Parallel Pr
