SUMMARY:Evaluating the Impact of Proposed OpenMP 5.0 Features on Performan
 ce, Portability, and Productivity
DESCRIPTION:Simon J. Pennycook, Jason D. Sewall, and Jeff R. Hammond (Inte
 l Corporation)\n\nWe investigate how specialization mechanisms proposed fo
 r OpenMP 5.0 -- specifically, the metadirective and declare variant direct
 ives -- may be deployed in a real-life code, using the miniMD benchmark fr
 om the Mantevo suite.\n\nAdditionally, we develop an OpenMP 4.5 implementa
 tion of miniMD that achieves a performance portability of 59.35% across co
 ntemporary CPU and GPU hardware,  discuss the processes of porting and ena
 bling this code, and show that the use of specialization would enable our 
 code to be expressed in a significantly more compact form, with implicatio
 ns for productivity.\n\nTag: Heterogeneous Systems, Performance\n\nRegistr
 ation Category: Workshop Reg Pass\n\nSession Chair: Rob Neely (Lawrence Li
 vermore National Laboratory)\n\n
