SUMMARY:Revisiting a Metric for Performance Portability
DESCRIPTION:Workshop\n\nRevisiting a Metric for Performance Portability\n\
 nPennycook, Sewall\n\nOur previously proposed metric for performance porta
 bility has been successful in spurring the development of tools and encour
 aging fair and meaningful evaluations of applications and programming fram
 eworks.  However, several practitioners have critiqued its formulation and
  questioned its interpretation.\n\nIn this presentation, we revisit and c
 larify our criteria for a useful performance portability metric, and prese
 nt a derivation of our metric from first principles to inform its interpre
 tation in a variety of scenarios. We explore the implications of this deri
 vation for practitioners, providing clear guidance for when it is appropri
 ate to use our metric and when alternative metrics are more suitable.\n\nT
