SUMMARY:Effective Performance Portability
DESCRIPTION:Workshop\nHeterogeneous Systems, Performance, Workshop Reg Pas
 s\n\nEffective Performance Portability\n\nHarrell, Kitson, Bird, Pennycook
 , Sewall...\n\nExascale computing brings with it diverse machine architect
 ures and programming approaches which challenge application developers. Ap
 plications need to perform well on a wide range of architectures while sim
 ultaneously minimizing development and maintenance overheads. In order to 
 alleviate these costs, developers have begun leveraging portability framew
 orks to maximize both the code shared between platforms and the performanc
 e of the application. We explore the effectiveness of several such framewo
 rks through applying them to small production codes. Throughout the proces
 s, we apply a logging tool to gather data on the development process. We u
 se this information to develop metrics of application development producti
 vity, which can be used to holistically assess how productively a performa
 nce-portable application was developed.
