SUMMARY:On Applying Performance Portability Metrics
DESCRIPTION:Workshop\n\nOn Applying Performance Portability Metrics\n\nDan
 iel, Panetta\n\nAs we prepare for further technological advancement in sup
 ercomputing, the diversity of hardware architectures and parallel programm
 ing languages has increased to new levels. At the same time, extracting pe
 rformance from so many architectures is even more difficult. In this conte
 xt, the appearance of portable languages capable of generating executable 
 code for multiple architectures has become a recurrent research target. We
  port a set of seven parallel benchmarks from SPEC ACCEL suite and a wave 
 propagation code to one such portable language: the Kokkos C++ programming
  library. Using the original OpenACC versions of the eight codes, we apply
  a known performance portability metric on the OpenACC and Kokkos versions
  of those codes across a variety of hardware platforms and problem sizes. 
 We observe that the portability metric is sensitive to the problem size. T
 o remedy this deficiency, we propose a novel metric for performance portab
 ility, apply the proposed metric to the eight codes and discuss the result
 s.\n\nTag: Workshop Reg Pass, Parallel Programming Languages, Libraries, a
